RT9728A - 1.3A Power Switch

Description

The RT9728A is a cost-effective, low-voltage, single P-MOSFET high-side power switch IC for USB applications with a programmable current limit feature.

Features

  • a low switch-on resistance (typically 120m) and a low supply current (typically 120A). The RT9728A offers a programmable current-limit threshold ranging from 75mA to 1.3A (typical) via an external resistor, With a ±10% current limit accuracy across all current limit settings. In addition, a flag output is available to indicate fault conditions to the local USB controller. Furthermore, the IC also integrates an embedded delay function to prevent misoperation due to high inrush current. The RT97.
