The DRV8340-Q1 device is an integrated gate driver for three-phase applications. The device provides three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The dedicated Source and Drain pins enable the independent MOSFET control for solenoid application. The DRV8340-Q1 generates the correct gate drive voltages using an integrated charge pump sufficient 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 DRV8340-Q1 can operate from a single power supply and supports a wide input supply range of 5.5 to 60 V for the gate driver.
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.
A low-power sleep mode is provided to achieve low quiescent current. Internal protection functions are provided for undervoltage lockout, charge pump fault, MOSFET overcurrent, MOSFET short circuit, phase-node short to supply and ground, gate driver fault, and overtemperature. Fault conditions are indicated on the nFAULT pin with details through the device registers for the SPI device variant.
