ZT2306A Datasheet | ZillTek

DESCRIPTION FEATURES The ZT2306/A provides plete Li+ charger - Input over-voltage protection protection against input over-voltage, input - Input over-current protection over-current, and battery over-voltage. When - Battery over-voltage protection any of the monitored parameters are over the - High immunity of false triggering threshold, the IC removes the power from the - High accuracy protection threshold charging system by turning off an internal - A built-in P-MOSFET switch. All protections also have deglitch time - Thermal shutdown protection against false triggering due to voltage spikes or - Ro HS pliant and 100% Lead (Pb) Free current transients. The ZT2306/A integrates a P-MOSFET with the APPLICATIONS body diode reverse protection to replace the - Cell phones external P-MOSFET and Schottky diode for charger function of cell phone’s PMIC. When the CHRIN voltage drops below VBAT+20m V, l the internal power select circuit will reverse ia the body diode’s terminal to prevent a reverse current flowing from the battery back to t CHRIN pin. k The ZT2306/A is available in the TDFN 2x2-8L n (EP) and SOT23-6L packages, and it is Ro HS e pliant and 100% lead (Pb) free. ill T ide ORDERING INFORMATION PART PACKAGE Ro HS Ship, Quantity f ZT2306D TDFN 2x2-8L Yes Tape and Reel ZT2306AD TDFN 2x2-8L Yes Tape and Real Z n ZT2306S SOT23-6L Yes Tape and Real ZT2306AS SOT23-6L Yes Tape and Real Pins Configuration Co Typical Application Circuit DS-01; Nov. 20, 2009 -1- Copyright © Zill Tek Technology Corp. 5F, No.2, Industry E. 9th Rd., Science-Based Industrial Park, Hsinchu 30075 Taiwan Tel: (886) 3577 7509; Fax: (886) 3577 7390 Email: sales@zilltek.
