Strap Battery PolySwitch Strap Battery Resettable Devices Raychem Circuit Protection, pioneer of polymeric PTC resettable devices, has developed several material platforms specifically tailored to help protect battery applications. Each of these material platforms offers different performance 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. 4 Benefits: Features: Applications: * Many material platforms and device form factors give engineers more design flexibility * Compatible with high-volume electronics assembly * Assists in meeting regulatory requirements * Low resistance devices increase battery operating time * Broad range of resettable devices available * Current ratings from 0.7A to 7.3A * Voltage ratings from 12V to 30V * Agency recognition, UL, CSA, TUV * Fast time-to-trip * Low resistance * * * * * * Mobile phone battery packs Cordless phone battery packs Mobile radio packs Computer battery packs Camcorder battery packs PDA battery packs Devices in this section are grouped by: Activation Temperature, Device Series, Hold Current Raychem Circuit Protection Devices PolySwitch Strap Battery Resettable Devices 259 Selection Guide for Strap Battery Devices 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 accommodate the circuit. Devices in this section are grouped by typical activation temperature; therefore, your operating current requirement may be found in more than one grouping. 4 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 interrupt 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 (I MAX). Ensure that VMAX and I MAX are greater than or equal to the circuits 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. 260 PolySwitch Strap Battery Resettable Devices Raychem Circuit Protection Devices Strap Battery Selection Guide for Strap Battery Devices Figures B19-24 show the typical time-to-trip at 20C 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 resistance-versus-temperature characteristics of various PolySwitch strap device series differ by use of different material platforms. Figure B2 shows the thermal cut-off behavior for each strap battery series device. Actual device performance 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 protection (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 temperatures are within the operating temperature range of -40C to 85C (except for VLR series, which is -40C to 70C). 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. Figure B1.

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. Latest Information * Please visit us at www.circuitprotection.com or contact your local representative for the latest information. * The information in this Databook may contain some preliminary information. Raychem Circuit Protection, a divsion of Tyco Electronics, reserves the right to change any of the specifications without notice. In addition, Tyco Electronics reserves the right to make changes--without notification to Buyer--to materials or processing that do not affect compliance with any applicable specification. Raychem Circuit Protection Devices PolySwitch Strap Battery Resettable Devices 283 4 WARNING: * Operation beyond the maximum ratings or improper use may result in device damage and possible electrical 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 recommendated 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. 4 284 PolySwitch Strap Battery Resettable Devices Raychem Circuit Protection Devices
