Product details

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

No lab, no bench: if you are swapping this on site, preheat the board from the bottom to avoid cold joints on the pad.

No last-time-buy risk for current production.

Frequently asked questions

What are the fault protection features of DRV8332DKD?

The DRV8332DKD integrates current limiting, over-temperature shutdown, short-circuit protection, and undervoltage lockout (UVLO). These protections operate without external sense resistors or comparators, simplifying the motor-drive BOM.

Does DRV8332DKD require an external bootstrap circuit?

No. The DRV8332DKD includes an internal bootstrap circuit, so you do not need external bootstrap diodes or capacitors for the high-side gate drive. The bootstrap flag output indicates when the bootstrap voltage is ready.

Is DRV8332DKD a suitable replacement for DRV8332?

The DRV8332DKD is the same base device as the DRV8332; the DKD suffix indicates the 36-HSSOP package variant with exposed pad. Check the package footprint compatibility — the 36-HSSOP is a surface-mount package, while some DRV8332 variants may come in a different package. The electrical ratings (52.5 V load, 8 A continuous, 13 A peak) are identical.
