GENERAL DESCRIPTION

The WT6621 is a dual integrated power switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements. With independent enable and error flag functions, the WT6621 can ease control the supplied power conditions of USB down stream; each switch channel can supplies up to 500mA to downstream devices; the switch low on-resistance meets USB voltage drop requirements; fault current is limited to typically 750mA, and a flag output is available to indicate fault conditions to the local USB controller. Additional features include thermal shutdown to prevent switch failure from high-current loads, undervoltage lockout (UVLO) to ensure there is a valid input voltage present, and 3.3V and 5V logic compatible enable inputs.

FEATURES

◆ Compliant to USB specifications

◆ Max. Continuous load current: 500mA

◆ 140m? maximum on-resistance per channel.

◆ 110uA typical on-state supply current

◆ 1uA typical off-state supply current

◆ Enable input is compatible with both 3V and 5V Logic

◆ Logic Over current output

◆ Undervoltage lockout

◆ Short Circuit Protection

◆ Thermal Shutdown

◆ Active-high or active-low enable versions

◆ 12KV output, 6KV input ESD protection.

◆ Packages: 8pin SOIC and 8pin DIP

Applications

◆ USB host and Self-power hubs

◆ USB bus-powered hub

◆ General purpose power switch applications
