Pin Functions

PIN I/O(1) DESCRIPTION
NAME NO.
BBSW 28 P Internal buck-boost converter switch pin. Connect an inductor from this point to source
DRAIN 1-11 P Power transistor drain
FAULT 32 O Fault output, push-pull, active low
IN 31 I CMOS-compatible non-inverting gate drive input
LDO5V 25 P 5-V LDO output for external digital isolator.
LPM 29 I Enables low-power-mode by connecting the pin to source
SOURCE 12-16, 18-24 P Power transistor source, die-attach pad, thermal sink, signal ground reference
RDRV 30 I Drive strength selection pin. Connect a resistor from this pin to ground to set the turn-on drive strength to control slew rate,
VDD 27 P 12-V power input, relative to source. Supplies 5-V rail and gate drive supply.
VNEG 26 P Negative supply output, bypass to source with 2.2-µF capacitor
NC 17 Not connected, connect to source or leave floating.
PAD P Thermal Pad, tie to source with multiple vias.
I = Input, O = Output, P = Power
