♠ DRV832x 6 to 60-V Three-Phase Smart Gate Driver
The DRV832x family of devices is an integrated gate driver for three-phase applications. The devices provide three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The DRV832x generates the correct gate drive voltages using an integrated charge pump for the high-side MOSFETs and a linear regulator for the low-side MOSFETs. The Smart Gate Drive architecture supports peak gate drive currents up to 1-A source and 2-A. The DRV832x can operate from a single power supply and supports a wide input supply range of 6 to 60 V for the gate driver and 4 to 60 V for the optional buck regulator.
The 6x, 3x, 1x, and independent input PWM modes allow for simple interfacing to controller circuits. The configuration settings for the gate driver and device are highly configurable through the SPI or hardware (H/W) interface. The DRV8323 and DRV8323R devices integrate three low-side current sense amplifiers that allow bidirectional current sensing on all three phases of the drive stage. The DRV8320R and DRV8323R devices integrate a 600-mA buck regulator.
A low-power sleep mode is provided to achieve low quiescent current draw by shutting down most of the internal circuitry. Internal protection functions are provided for undervoltage lockout, charge pump fault, MOSFET overcurrent, MOSFET short circuit, gate driver fault, and overtemperature. Fault conditions are indicated on the nFAULT pin with details through the device registers for SPI device variants.
