DRV8301QDCAQ1 Semiconductors Power Management ICs Motor Controllers Drivers

The DRV8301-Q1 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, two current shunt amplifiers, and a switching buck converter. The DRV8301-Q1 provides overcurrent, overtemperature, 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 used to prevent flow of current. VDS sensing of the external MOSFETs allows for the DRV8301-Q1 to detect overcurrent conditions and respond appropriately. Individual MOSFET overcurrent conditions are reported through the SPI status registers. The highly configurable buck converter can support a wide range of output options. This allows the DRV8301-Q1 to provide a power supply rail for the controller and lower voltage components.
