DRV8343SPHPRQ1 Description

The DRV8343SPHPRQ1 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 DRV8343SPHPRQ1 generates the correct gate drive voltages using an integrated charge pump sufficient for the high-side MOSFETs and alinear 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 DRV8343-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.
