3 Description

The BQ24392 is a dual single-pole single-throw

(SPST) USB 2.0 high-speed isolation switch with

charger detection capabilities for use with micro and

mini-USB ports. This USB switch allows mobile

phones, tablets, and other battery operated

electronics to be charged from different adapters with

minimal system software. The device’s charger

detection circuitry can support USB Battery Charging

Specification version 1.2 (BCv1.2) compliant,

Apple™, TomTom™, and other non-standard

chargers.

The BQ24392 device is powered through VBUS when

a charger is attached to the micro or mini-USB port

and has a 28-V tolerance to avoid the need for

external protection.
