5.1 Recommendations
•HIN and LIN are active-high logic input signals, each having an integrated 500 kΩ (typ.)
pull-down resistor. Wire each input as short as possible and use RC filters (R1, C1) on
each to prevent input signal oscillation. The filters should have a time constant of
approximately 100 ns and must be placed as close as possible to the IPM input pins.
•Use a bypass capacitor Cvcc (aluminum or tantalum) to reduce the transient circuit
demand on the power supply and a decoupling capacitor C2 (from 100 to 220 nF,
ceramic with low ESR), placed as close as possible to each Vcc pin and in parallel to
the bypass capacitor, to reduce high frequency switching noise distributed on the
power supply lines.
•To prevent circuit malfunction, place an RC filter (RSF, CSF) with a time constant (RSF
x CSF) of 1µs as close as possible to the CIN pin.
•The SD is an input/output pin (open drain type if used as output). An integrated NTC
thermistor is connected internally between the SD pin and GND. The pull-up resistor
RSD causes the voltage VSD-GND to decrease as the temperature increases. To
always maintain the voltage above the high-level logic threshold, use a 1 kΩ or 2.2 kΩ
pull-up resistor for a 3.3 V or 5 V MCU power supply, respectively. Size the filter on SD
appropriately to obtain the desired re-start time after a fault event, and locate it as close
as possible to the SD pin .
•Filter high-frequency disturbances by placing the decoupling capacitor C3 (from 100 to
220 nF, ceramic with low ESR) in parallel with each Cboot.
•Prevent overvoltage with Zener diodes DZ1 between the V
CC
pins and GND and in
parallel with each Cboot.
•Locate the decoupling capacitor C4 (from 100 to 220 nF, ceramic with low ESR) in
parallel with the electrolytic capacitor Cvdc to prevent surge destruction. Place
capacitors C4 (especially) and Cvdc as close as possible to the IPM.
•By integrating an application-specific type HVIC inside the module, direct coupling to
the MCU terminals without an opto-coupler is possible.
•Use low inductance shunt resistors for phase leg current sensing.
•The wiring between N pins, the shunt resistor and PWR_GND should be as short as
possible.
•Connect SGN_GND to PWR_GND at only one point (near the shunt resistor terminal),
to avoid any malfunction due to power ground fluctuation.
