7.1 Overview
The DRV8303 is a 6-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 and two current shunt amplifiers. The DRV8303
provides overcurrent, over-temperature, and undervoltage protection. Fault conditions are indicated through the
nFAULT and nOCTW pins in addition to the SPI registers.
Adjustable dead time control and peak gate drive current allows for finely tuning the switching of the external
MOSFETs. Internal hand shaking is usedd to prevent through current.
V_DS sensing of the external MOSFETs allows for the DRV8303 to detect overcurrent conditions and respond
appropriately. Individual MOSFET overcurrent conditions are reported through the SPI status registers.
