65-V max 3-phase smart gate driver with buck regulator
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-sideN-channel power MOSFETs. The DRV832x generates the correct gate drive voltages using an integratedcharge pump for the high-side MOSFETs and a linear regulator for the low-side MOSFETs. The SmartGate Drive architecture supports peak gate drive currents up to 1-A source and 2-A. The DRV832x canoperate from a single power supply and supports a wide input supply range of 6 to 60 V for the gatedriver and 4 to 60 V for the optional buck regulator.
The 6x, 3x, 1x, and independent input PWM modes allow for simple interfacing tocontroller circuits. The configuration settings for the gate driver and device are highlyconfigurable through the SPI or hardware (H/W) interface. The DRV8323 and DRV8323R devicesintegrate three low-side current sense amplifiers that allow bidirectional current sensing on allthree phases of the drive stage. The DRV8320R and DRV8323R devices integrate a 600-mA buckregulator.
A low-power sleep mode is provided to achieve low quiescent current draw by shutting downmost of the internal circuitry. Internal protection functions are provided for undervoltagelockout, charge pump fault, MOSFET overcurrent, MOSFET short circuit, gate driver fault, andovertemperature. Fault conditions are indicated on the nFAULT pin with details through the deviceregisters for SPI device variants.
