Overview
EST.
5198 USB Charger Enhance IC GENERAL DESCRIPTION The EST.
5198 is designed for most of mainstream USB device to draw a charge current as much as possible from adapter.
The EST.
5198 can recognize and change the USB charging mode for the different USB device.
The IC set the USB interface signals (D+/D-) to the required condition and the handheld charging device will start to charge .
The IC support most of the worldwide charging specification like the USB BC specification, mainstream handheld charging specification.
FEATURE ■ Support most of mainstream USB device fast charging ■ Support the 1A/2A charging mode ■ SOT23-5 package PIN CONFIGURATION (Top View) REFERENCE APPLICATION CIRCUIT PIN DESCRIPTION Pin Symbol 1 MODE Type I 2 GND 3 VCC 4 D＋ 5 D－ B B Function Internal default pull high： Pull high: Apple 2A mode Pull low : Apple 1A mode Ground Power USB positive data USB negative data ABSOLUTE MAXIMUN RATINGS Supply Voltage PARAMETER VCC Input / Output Voltage MODE, D＋, D－ Operating Temperature Range Storage Temperature Range TO TS MIN -0.
