7.1 Overview
The DRV8302 is a 8-V to 60-V, gate driver IC for three phase motor drive applications. This device reduces
external component count by integrating three half-bridge drivers, two current shunt amplifiers, and a switching
buck converter. The DRV8302 provides overcurrent, overtemperature, and undervoltage protection. Fault
conditions are indicated through the nFAULT and nOCTW pins.
Adjustable dead time control allows for finely tuning the switching of the external MOSFETs. Internal hand
shaking is used to prevent shoot-through current. VDS sensing of the external MOSFETs allows for the
DRV8302 to detect overcurrent conditions and respond appropriately. The VDS trip point can be set through a
hardware pin.
The highly configurable buck converter can support a wide range of output options. This allows the DRV8302 to
provide a power supply rail for the controller and lower voltage components.
