MAX8804W

19-0785; Rev 1; 10/07 KIT ATION EVALU E L B A AVAIL High-Voltage, Dual-Input, USB/AC Adapter Chargers in 2mm x 3mm TDFN General Description Features ♦ Complete Chargers for Single-Cell Li+ Battery ♦ Dual-Input, 30V AC Adapter/16V USB ♦ No External FET, Blocking Diode, or Sense Resistor Required ♦ Automatic USB/AC Adapter Input Selection ♦ Easy Programmable Fast-Charge Current and Top-Off Threshold ♦ Proprietary Die Temperature Regulation Control ♦ ±5% Fast-Charge Current-Limit Accuracy ♦ Battery Pack Detection Input (MAX8804W) ♦ Power-Present and Charger-Status Outputs ♦ No Prequalification Charge (MAX8804Y) ♦ Tiny 2mm x 3mm Thermally Enhanced TDFN Package ♦ USB Charging Protected by US Patent #6,507,172 MAX8804W/MAX8804Y/MAX8804Z The MAX8804W/MAX8804Y/MAX8804Z intelligent, dual-input, stand-alone, constant-current, constant-voltage (CCCV), thermally regulated linear chargers are designed for a single-cell lithium-ion (Li+) battery. They integrate the current-sense circuit, MOS pass element, thermal-regulation circuitry, and overvoltage protection (OVP), and eliminate the reverse-blocking Schottky diode to create a simple and small charging solution for handheld equipment. www.DataSheet4U.com The MAX8804W/MAX8804Z function as stand-alone chargers to control the charging sequence from the prequalification state through fast-charge, top-off charge, and full-charge indication. The MAX8804Y eliminates the prequalification state to allow startup into a load without a battery. ...
