RT9701GBL

Overview

The RT9701GBL is a single-channel power distribution switch manufactured by Richtek Technology Corporation, designed for Universal Series Bus (USB) applications. It integrates a high-side N-channel NMOSFET with a typical on-resistance of 100mΩ and utilizes a built-in charge pump to eliminate parasitic body diode reverse current flow when powered off. The device supports an input voltage range of 2.2V to 6V and guarantees a continuous current of 1.1A with a 1.5A current limit. Key electrical parameters include a low quiescent supply current of 23µA and operation within a standard temperature range.

Feature Summary

Integrated charge pump drives the N-channel NMOSFET to prevent reversed current flow across the switch when powered off
Low quiescent supply current minimizes power consumption in battery-powered portable equipment
Built-in thermal protection safeguards against overheating during fault conditions

Applications

Self-powered USB peripheral devices
Bus-powered USB hub ports
Battery-operated portable electronic equipment
Universal Serial Bus power distribution circuits

Procurement Notes

Verify the specific suffix GBL against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets UL approval requirements if used in certified end-products. Confirm availability status as older revisions may have different packaging or lead times compared to current production units.

Selection Notes

Select this component for applications requiring low board space and minimal static power draw. The integrated charge pump feature distinguishes it from switches lacking reverse current blocking. Consider the 1.1A continuous current rating and 1.5A limit when designing for peak load scenarios. The wide input voltage range accommodates various USB power standards.

Part Context

The RT9701 series belongs to Richtek's family of 100mΩ power distribution switches. Variants such as RT9701B and RT9701BPB share similar functional descriptions but may differ in package options or specific electrical tolerances. The RT9701GBL specifically denotes the SOT-25 package configuration optimized for space-constrained designs.
