What this three-phase driver brings to the board
The Texas Instruments DRV8332DKD is a three-phase power MOSFET driver designed for PWM-controlled DC motors and general-purpose inductive loads. It integrates three half-bridge outputs rated at 52.5 V maximum load voltage, with 8 A continuous and 13 A peak current per channel. The internal bootstrap circuit and status-flag output reduce external component count, while built-in fault protection — current limiting, over-temperature, short-circuit, and undervoltage lockout (UVLO) — lets you skip adding a separate supervisor IC on the motor-drive rail.
Package and mounting — field-fit check
Housed in a 36-lead HSSOP with an exposed thermal pad (11.00 mm body width), this is a surface-mount part. The thermal pad is the primary heat path — the board needs a via array under the pad to pull heat into the inner copper planes. No lab, no bench: if you are swapping this on site, preheat the board from the bottom to avoid cold joints on the pad. The supplier device package is 36-HSSOP, and the part ships in Tube form.
Lifecycle and sourcing posture
The DRV8332DKD carries an Active lifecycle status with ROHS3 compliance. No last-time-buy risk for current production.
