PolySwitch Strap Battery
Resettable Devices
Raychem Circuit Protection, pio-
neer of polymeric PTC resettable
devices, has developed several
material platforms specifically tai-
lored to help protect battery
applications. Each of these mate-
rial platforms offers different per-
formance characteristics,
allowing the engineer greater
design flexibility. Raychem Circuit
Protection’s battery protection
family includes SRP, LTP, LR4,
VTP, and VLR series, disc, and
special application strap devices.
Benefits:
• Many material platforms and
device form factors give engi-
neers more design flexibility
• Compatible with high-volume
electronics assembly
• Assists in meeting regulatory
requirements
• Low resistance devices
increase battery operating time
Features:
• Broad range of resettable
devices available
• Current ratings from 0.7A to
7.3A
• Voltage ratings from 12V to 30V
• Agency recognition, UL, CSA,
TÜV
• Fast time-to-trip
• Low resistance
Applications:
• Mobile phone battery packs
• Cordless phone battery packs
• Mobile radio packs
• Computer battery packs
• Camcorder battery packs
• PDA battery packs

Step 1. Determine the circuit’s operating parameters.
Fill in the following information about the circuit:
Maximum ambient operating temperature
Normal operating current
Maximum operating voltage
(i.e., VTP210G is 16V max.)
Maximum interrupt current
Step 2. Select the PolySwitch device that will accommodate the
circuit’s maximum ambient temperature and
normal operating current.
Look across the top of Table B2 to find the temperature that most
closely matches the circuit’s maximum operating temperature. Look
down the column to find the value equal to or greater than the circuit's
normal operating current. Now look to the far left of that row to find the
part number for the PolySwitch strap device that will best accommo-
date the circuit. Devices in this section are grouped by typical activa-
tion temperature; therefore, your operating current requirement may be
found in more than one grouping.
The thermal derating curves located in Figure B3 are the normalized
representations of the data in Table B2.
Step 3. Compare the selected device’s electrical ratings with the
circuit’s maximum operating voltage and maximum inter-
rupt current.
Look down the first column of Table B3 to find the part number you
selected in Step 2. Look to the right in that row to find the device’s
maximum operating voltage (VMAX) and maximum interrupt current
(IMAX). Ensure that VMAX and IMAX are greater than or equal to the cir-
cuits maximum operating voltage and maximum interrupt current.
Step 4. Determine time-to-trip.
Time-to-trip is the amount of time it takes for a device to switch to a
high-resistance state once a fault current has been applied across the
device. Identifying the PolySwitch device’s time-to-trip is important in
order to provide the desired protection capabilities. If the device you
choose trips too fast, undesired or nuisance tripping will occur. If the
device trips too slowly, the components being protected may be
damaged before the device switches to a high resistance state.

Figures B19-24 show the typical time-to-trip at 20°C for each of the
PolySwitch devices.
If the PolySwitch device time-to-trip is too fast or too slow for the circuit, go
back to Step 2 and choose an alternate device.
Step 5. Match Thermal Cut-Off to Cell Chemistry.
Thermal cut-off is the temperature at which a PolySwitch device will trip
when sourced with a specific current. Figure B1 demonstrates how the resis-
tance-versus-temperature characteristics of various PolySwitch strap device
series differ by use of different material platforms. Figure B2 shows the ther-
mal cut-off behavior for each strap battery series device. Actual device per-
formance can vary depending on the application environment, and users
should independently test and evaluate each product in their application.
Thermally sensitive cell chemistries such as Li-ion and NiMH typically use
devices with lower thermal cut-off, which can provide enhanced thermal pro-
tection (VLR and VTP series). Less sensitive chemistries, like NiCd, typically
use devices with higher thermal cut-off temperatures (LR4, SRP series).
Step 6. Verify ambient operating conditions.
Ensure that your application’s minimum and maximum ambient tempera-
tures are within the operating temperature range of -40°C to 85°C (except
for VLR series, which is -40°C to 70°C).
Step 7. Verify the PolySwitch device dimensions.
Using dimensions in Table B4, compare the dimensions of the PolySwitch
device you selected with the application’s space considerations.

Notes:
IH= Hold current: maximum current device will pass without interruption in 20°C still air unless otherwise specified.
IT= Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air unless otherwise specified.
VMAX = Maximum voltage device can withstand without damage at rated current.
IMAX = Maximum fault current device can withstand without damage at rated voltage.
PD= Power dissipated from device when in the tripped state in 20°C still air unless otherwise specified.
RMIN = Minimum resistance of device as supplied at 20°C unless otherwise specified.
RTYP = Typical resistance of device as supplied at 20°C unless otherwise specified.
RTripped Typ = Typical resistance, measured at 20°C unless otherwise specified, of device one hour after being tripped the first time.
RMAX = Maximum resistance of device as supplied at 20°C unless otherwise specified.
†= Product electrical characteristics determined at 25°C.
* = R1max value for this device is the maximum resistance of the device at 20°C one hour after reflow.

Installation Guidelines for the Strap Family
•Polymeric PTC devices operate by thermal expansion of the conductive polymer. If devices are placed under
pressure or installed in spaces that would prevent thermal expansion, they may not properly protect against
fault conditions. Designs must be selected in such a manner that adequate space is maintained over the life
of the product.
•Twisting, bending, or placing the PPTC device in tension will decrease the ability of the device to protect
against electrical faults. No residual force should remain on device after installation. Mechanical damage
to PPTC chip may affect device performance and should be avoided.
•Chemical contamination of PPTC devices should be avoided. Certain greases, solvents, hydraulic fluids,
fuels, industrial cleaning agents, volatile components of adhesives, silicones, and electrolytes can have an
adverse effect on device performance.
•PPTC strap devices are designed to be resistance welded to battery cells or to pack interconnect straps,
yet some precautions must be taken when doing so. In order for the PPTC device to exhibit its specified
performance, weld placement should be a minimum of 2mm from the edge of the PPTC chip, weld splatter
must not touch the PPTC chip, and welding conditions must not heat the PPTC device above its maximum
operating temperature.
•PPTC strap devices are not designed for applications where reflow onto flex circuits or rigid circuit boards
is required.
•The polyester tape on PolySwitch strap devices is intended for marking and indentification purposes only,
not for electrical insulation.

• Operation beyond the maximum ratings or improper use may result in device damage and possible elec-
trical arcing and flame.
• The devices are intended for protection against occasional overcurrent or overtemperature fault conditions
and should not be used when repeated fault conditions or prolonged trip events are anticipated.
• Contamination of the PPTC material with certain silicon based oils or some aggressive solvents can
adversely impact the performance of the devices.
• Device performance can be impacted negatively if devices are handled in a manner inconsistent with rec-
ommendated electronic, thermal, and mechanical procedures for electronic components.
• Operation in circuit with a large inductance can generate a circuit voltage (L di/dt) above the rated voltage
of the PolySwitch resettable device.
