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 -0.3 -0.3 -20 -65 MAX 7 7 +85 150 UNITS V V oC oC www.esthome.com - 1 - Datasheet Rev. 1.0 EST.5198 USB Charger Enhance IC ELECTRICAL CHARACTERISTICS ( For VCC=5V and Tj=25 oC ) PARAMETER CONDITIONS MIN VCC Operating Range, Vcc 4.5 Operating current, Icc Vcc=5V MODE, D+, D- D+Output Impedance Vcc=5V 17.4 D-Output Impedance Vcc=5V 22.6 D+, D- 0 MODE pull high Impedance Vcc=5.5V Mode 0 TYP 300 10 MAX 5.5 25.8 37.6 Vcc, Vcc UNITS V uA KΩ KΩ V KΩ FUNCTION DESCRIPTION 1. The IC can set the proper USB interface signal to support USB port charging for most of the mainstream handheld device. 2. The IC will draw the charging current as much as the USB adapter could for the USB handheld device. That can reduce the charging time when use the IC as the charging kit. 3. SEL truth table SEL Function 0 Apple 1A mode 1 Apple 2A mode If select the 2A mode, please make sure the adapter power source can provide 5V/2A for the USB charging port. 4. The EST.5198 control the D+/ D- signals of the USB port to support the charging procedure and does not control the USB power (VBUS) operation. www.esthome.com - 2 - Datasheet Rev. 1.0 EST.5198 USB Charger Enhance IC PACKAGE DIMENSIONS SOT23-5 www.esthome.com - 3 - Datasheet Rev. 1.0 .
