RT9721B switches equivalent, 500ma high-side power switches.
include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) t.
The RT9721A/B series provides a charge pump circuitry to drive the internal MOSFET switch; the switch's low RDS(ON), 80.
The RT9721A/B are low voltage, single N-MOSFET highside power switches, optimized for self-powered and buspowered Universal Serial Bus (USB) applications. The RT9721A/B series provides a charge pump circuitry to drive the internal MOSFET switch; the .
