PIN TYPE DESCRIPTION
NAME NO.
DRV8161
20-pin		 DRV8162, DRV8162L
20-pin
DT/MODE 1 1 I Selects input pin interface logic and gate drive dead time setting. Connect a resistor between DT and GND to adjust dead time between 20 ns to 1000 ns, and select a PWM mode.
INLH/IN 2 2 I Gate driver control input. Gate driver control depends on DT/MODE pin setting.
INL/EN 3 3 I Gate driver control input. Gate driver control depends on DT/MODE pin setting.
NC — 4 N/A No Connect. Leave open.
nDRVOFF — 5 I Gate driver shutdown control. Pulling nDRVOFF low turns off high-side and low-side external MOSFETs by putting the gate drivers into the pull-down state.
nFAULT/nDRVOFF 4 — I/OD Shared fault indicator pin and gate driver shutdown pin. Connect this pin to an external pull-up resistor to the controller supply or a controller output pin. This pin is pulled logic low during a fault condition. To active gate drive shutdown, pull the pin low by external logic.
nFAULT — 6 OD Fault indicator output. This pin is pulled logic low during a fault condition and requires an external pull-up resistor to controller I/O supply, 3.3V to 5.0V.
VDSLVL 5 7 I VDS monitor threshold setting. This pin is a multilevel input pin set by an external resistor.
CSAREF 6 — PWR Current sense amplifier reference. Connect a capacitor between the CSAREF and GND pins.
SO 7 — O Current sense amplifier output.
CSAGAIN 8 — I Gain settings for current sense amplifier. This pin is a multilevel input pin set by an external resistor.
IDRIVE1 9 8 I Gate drive source and sink current setting. This pin is a multilevel input pin set by an external resistor.
NC 9, 16 No Connect. Leave open.
GVDD 10 10 PWR Gate driver power supply input. Connect a capacitor between the GVDD and GND pins.
IDRIVE2 11 11 I Gate drive source and sink current setting. This pin is a multilevel input pin set by an external resistor.
GND 12 12 PWR Device ground.
GVDD_LS — 13 PWR Low-side gate driver power supply input (DRV8162 and DRV8162L only). Connect a capacitor between the GVDD_LS and GND pins.
SN 13 — I Current sense amplifier input. Connect to the low-side of the current shunt resistor.
SP 14 — I Current shunt amplifier input. Connect to the low-side power MOSFET source and high-side of the current shunt resistor.
SL 15 14 I Low-side source pin. Connect to the low-side power MOSFET source. This pin is an input for the VDS monitor and the output for the low-side gate driver sink.
GL 16 15 O Low-side gate driver output. Connect to the gate of the low-side power MOSFET.
GH 17 17 O High-side gate driver output. Connect to the gate of the high-side power MOSFET.
SH 18 18 I High-side source pin. Connect to the high-side power MOSFET source. This pin is an input for the VDS monitor and the output for the high-side gate driver sink.
BST 19 19 O Bootstrap output pin. Connect a capacitor between BST and SH.
VDRAIN 20 20 PWR High-side MOSFET drain sense input for VDS monitor and charge pump reference. Connect to the high-side MOSFET drain.
THERMAL PAD PWR Leave open, or tied to GND
