Boost diodes are provided for high side gat e bo ost drive.
Function
Single control power supply due to Internal bootstrap circuit for high side pre-driver circuit

Notes:
1. When the internal protection circuit operates, a Fault signal is turned ON (When the Fault terminal is low level, Fault signal is ON
state : output form is open DRAIN) but the Fault signal does not latch.After protection operation ends,it returns automatically within
about 6ms to 12ms and resumes operation beginning condition. So, after Fault signal detection, set all input signals to OFF (Low)
at once.However, the operation of pre-drive power supply low voltage protection (UVLO:with hysteresis about 0.2V) is as follows.
Upper side:
The gate is turned off and will return to regular operation when recovering to the normal voltage, but the latch will continue till the
input signal will turn ‘low’.
Lower side:
The gate is turned off and will automatically reset when recovering to normal voltage. It does not depend on input signal voltage.
2. When assembling the IPM on the heat sink with M3 type screw, tightening torque range is 0.6 Nm to 0.9 Nm.
3. The pre-drive low voltage protection is the feature to protect devices when the pre-driver supply voltage falls due to an operating
malfunction.
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be
indicated by the Electrical Characteristics if operated under different conditions.

Input / Output Timing Diagram

Notes
*1 : Diagram shows the prevention of shoot-through via control logic. More dead time to account for switching delay needs to be
added externally.
*2 : When VDD decreases all gate output signals will go low and cut off all of 6 IGBT outputs. When VDD rises the operation will
resume immediately.
*3 : When the upper side gate voltage at VB1, VB2 and VB3 drops only, the corresponding upper side output is turned off. The
outputs return to normal operation immediately after the upper side gate voltage rises.
*4 : In case of over current detection, all IGBT’s are turned off and the FAULT output is asserted. Normal operation resumes in 6 to
12ms after the over current condition is removed.

Usage Precaution
1. This IPM includes bootstrap diode and resistors. Therefore, by adding a capacitor “CB”, a high side drive voltage is generated;
each phase requires an individual bootstrap capacitor. The recommended value of CB is in the range of 1 to 47μF, h o we v e r th i s
value needs to be verified prior to production. If selecting the capacitance more than 47μF (±20%), connect a resistor (about
20Ω) in series between each 3-phase upper side power supply terminals (VB1,2,3) and each bootstrap capacitor.
When not using the bootstrap circuit, each upper side pre-drive power supply requires an external independent power supply.
2. It is essential that wirning length between terminals in the snubber circuit be kept as short as possible to reduce the effect of
surge voltages. Recommended value of “CS” is in the range of 0.1 to 10μF.
3. “ISO” (pin22) is terminal for current monitor. When the pull-down resistor is used, please select it more than 5.6kΩ
4. “FLTEN” (pin21) is open DRAIN output terminal (Active Low). Pull up resistor is recommended more than 5.6kΩ.
5. Inside the IPM, a thermistor used as the temperature monitor for internal subatrate is connected between VSS terminal and VTH
terminal, therefore, an external pull up resistor connected between the TH terminal and an external power supply should be used.
The temperature monitor example application is as follows, please refer the Fig.10 and below.
6. The over-current protection feature is not intended to protect in exceptional fault condition. An external fuse is recommended for
safety.
7. When “N” and “VSS” terminal are short-circuited on the outside, level that over-current protection (ISD) might be changed from
designed value as IPM. Please check it in your set (“N” terminal and “VSS” terminal are connected in IPM).
8. When input pulse width is less than 1.0μs, an output may not react to the pulse. (Both ON signal and OFF signal)
This data shows the example of the application circuit, does not guarantee a design as the mass production set.
Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended
Operating Ranges limits may affect device reliability.

CB capacitor value calculation for bootstrap circuit
Calculate conditions
Cap acitance calculation formula
Thus, the following formula are true
VBS x CB - QG - IDMAX * TONMAX = UVLO * CB
therefore,
CB = (QG + IDMAX * TONMAX) / (VBS - UVLO)
The relationship between TONMAX and CB becomes as follows. CB is recommended to be approximately 3 times the value calculated
above. The recommended value of CB is in the range of 1 to 47μF, however, this value needs to be verified prior to production.
