Description

CHY103 is a USB mobile device charger interface IC which implements

the Qualcomm’s Quick Charge 3.0 specification for adaptive voltage

battery charging. It incorporates all necessary functions to add Quick

Charge 3.0 capability to circuits incorporating Power Integrations’

switcher ICs such as InnoSwitch, TinySwitch, TOPSwitch and other

charger solutions employing traditional secondary-side feedback

schemes.

CHY103 supports the full output voltage range of Quick Charge 3.0,

including 200 mV micro-stepped voltage levels from 3.6 V to 12 V

(Class A) and up to 20 V (Class B). CHY103 provides a suite of system

level protection features protecting the power supply and connected

Powered Device (PD) from excessive output voltages, secondary-side

thermal overload, and faulty power delivery while adapter is unplugged.

Additionally it allows the PD to remotely shutdown the power supply

through USB data lines. The shutdown type can be configured as

either hysteretic or latching.

CHY103 automatically detects whether a connected PD is Quick Charge

3.0 or Quick Charge 2.0 capable before enabling output voltage

adjustment. If a PD that is not compliant to Quick Charge 2.0 or 3.0 is

detected, the CHY103 disables output voltage adjustment to ensure

safe operation with legacy 5 V only USB PDs.
