DESCRIPTION

NAME DRV8312 DRV8332

Overtemperature warning signal, open-drain, active-low. An internal pull-up resistor

OTW 21 2 O to VREG (3.3 V) is provided on output. Level compliance for 5-V logic can be

obtained by adding external pull-up resistor to 5 V

OUT_A 28 33 O Output, half-bridge A

OUT_B 31 30 O Output, half-bridge B

OUT_C 39 22 O Output, half-bridge C

PVDD_A 26,27 34 P Power supply input for half-bridge A requires close decoupling capacitor to ground.

PVDD_B 32 29 P Power supply input for half-bridge B requires close decoupling capacitor to gound.

PVDD_C 40,41 21 P Power supply input for half-bridge C requires close decoupling capacitor to ground.

PWM_A 17 4 I Input signal for half-bridge A

PWM_B 15 6 I Input signal for half-bridge B

PWM_C 5 16 I Input signal for half-bridge C

RESET_A 16 5 I Reset signal for half-bridge A, active-low

RESET_B 7 15 I Reset signal for half-bridge B, active-low

RESET_C 6 15 I Reset signal for half-bridge C, active-low

Fault signal, open-drain, active-low. An internal pull-up resistor to VREG (3.3 V) is

FAULT 18 3 O provided on output. Level compliance for 5-V logic can be obtained by adding

external pull-up resistor to 5 V

Power supply for digital voltage regulator requires capacitor to ground for

VDD 2 17 P

decoupling.

VREG 11 10 P Digital regulator supply filter pin requires 0.1-μF capacitor to AGND.

Solder the exposed thermal pad at the bottom of the DRV8312DDW package to the

THERMAL PAD -- N/A T landing pad on the PCB. Connect the landing pad through vias to large ground

plate for better thermal dissipation.

Mount heatsink with thermal interface to the heat slug on the top of the

HEAT SLUG N/A -- T

DRV8332DKD package to improve thermal dissipation.
