7.1 Overview

The DRV8351-SEP family of devices are gate drivers for three-phase motor drive applications. These devices decrease system component count, saves PCB space and cost by integrating three independent half-bridge gate drivers and optional bootstrap diodes.

DRV8351-SEP supports external N-channel high-side and low-side power MOSFETs and can drive 750mA source, 1.5A sink peak currents with a total combined 30mA average output current. The DRV8351-SEP family of devices are available in 0.65mm pitch TSSOP surface-mount packages. The TSSOP body size is 6.5 × 4.4mm (0.65mm pin pitch) for the 20-pin package.
