RT9721B Product details

Description

The RT9721A/B are low voltage, single N-MOSFET highside power switches, optimized for self-powered and buspowered Universal Serial Bus (USB) applications.

Features

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) to ensure that the device remains off unless there is a valid input voltage present. The maximum current is limited to typically 750mA in dual ports in accordance with the USB power requirements, lower quiescent current as 50uA making this device ideal for portable battery-operated equipment. The RT9721A is designed without outpu.
