Features

Description

Compliant to USB Specifications

Two Independent Switches

GM2526 is a dual high-side integrated power switch with in-

dependent enable and flag functions, designed for self-

powered and bus-powered Universal Serial Bus (USB) ap-

plications. GM2526 requires few external components.

Input from 3V to 5.5V

Min. Continuous Load Current 500mA per port

Max. ON-Resistance 140mW

Max. Short Circuit Current Limit 1.25A

Individual Open-Drain Fault Flag Pins

ON-State Supply Current 110µA (typ.)

OFF-State Supply Current 0.75µA (typ.)

Thermal Shutdown

Each of the two switch channels supply up to 500mA as

required by USB downstream devices. Each switch’s low

on-resistance meets USB voltage drop requirements. Fault

current is 750mA (typical). A flag output indicates fault

conditions to the local USB controller. The soft-start feature

prevents the transient voltage drop on the upstream port

that can occur when the switch is enabled in bus-powered

applications. Thermal shutdown protection prevents switch

failure from high-current loads. Undervoltage lockout

(UVLO) hold GM2526 off unless there is a correct input

voltage. GM2526 has 3.3V and 5V logic-compatible Enable

inputs.

Undervoltage Lockout (UVLO) Typically 2.4V

1ms Turn-ON (soft-start) and Fast Turn-OFF
