JSM6288Q

JSM6288Q is a JSMSEMI three-phase gate driver in a QFN-24 package, for brushless DC and PMSM motor drives: an 8 V to 20 V driver supply, a floating high-side channel rated to 225 V, and 1.5 A source / 1.8 A sink drive current, with built-in dead-time control and cross-conduction (shoot-through) protection — one driver IC between the motor-control MCU and all six MOSFETs of a three-phase bridge, for fans, pumps, appliances and power tools. The protection set is the selection point: dead-time insertion and interlock against both switches in a leg turning on together are handled in the driver, which removes a class of bridge-destruction faults that discrete gate drive leaves to firmware timing. Selection advice: qualify this part against JSMSEMI's own manual for the device (document JS-MOS-D-6288Q) — JSMSEMI documents its own figures for its codes, and same-function driver ICs from other makers differ in thresholds, dead-time and protection behaviour, so pin-compatible does not mean datasheet-identical. Check that the 225 V floating rating covers your DC bus with margin before committing the design. Parameters verified against JSMSEMI documentation.
