MAX8804V/MAX8804W/MAX8804Y/MAX8804Z 19-0785 Rev 2 4/08 High-Voltage, Dual-Input, USB/AC Adapter Chargers in 2mm x 3mm TDFN General Description Features Complete Chargers for Single-Cell Li+ Battery The MAX8804V/MAX8804W/MAX8804Y/MAX8804Z intelligent, dual-input, stand-alone, constant-current, Dual-Input, 30V AC Adapter/16V USB constant-voltage (CCCV), thermally regulated linear No External FET, Blocking Diode, or Sense chargers are designed for a single-cell lithium-ion (Li+) Resistor Required battery. They integrate the current-sense circuit, MOS Automatic USB/AC Adapter Input Selection pass element, thermal-regulation circuitry, and overvolt- age protection (OVP), and eliminate the reverse-block- Easy Programmable Fast-Charge Current and ing Schottky diode. Top-Off Threshold Proprietary Die Temperature Regulation Control The MAX8804V/MAX8804W/MAX8804Z function as stand-alone chargers to control the charging sequence 5% Fast-Charge Current-Limit Accuracy from the prequalification state through fast-charge, top- Battery Pack Detection Input off charge, and full-charge indication. The MAX8804Y (MAX8804V/MAX8804W) eliminates the prequalification state to allow startup into a Power-Present and Charger-Status Outputs load without a battery. Proprietary thermal-regulation cir- No Prequalification Charge (MAX8804Y) cuitry limits the die temperature when fast-charging or while exposed to high ambient temperatures, allowing Tiny 2mm x 3mm Thermally Enhanced TDFN maximum charging current without damaging the IC. Package The MAX8804V/MAX8804W/MAX8804Y/MAX8804Z achieve high flexibility by providing an adjustable DC/USB Ordering Information fast-charge current through a simple single-wire interface (SET input). The chargers automatically select between PIN- TOP either a USB or AC adapter input source. The AC adapter PART PACKAGE MARK charge current is programmable from 400mA to 700mA in 50mA steps through a serial interface. The USB charge MAX8804VETA+ 8 TDFN-EP* AAQ current is programmable to 95mA, 380mA, or 475mA MAX8804WETA+ 8 TDFN-EP* AAP through the same interface. Other features include an MAX8804YETA+ 8 TDFN-EP* AAD active-low battery charging-status indicator (CHG), an MAX8804ZETA+ 8 TDFN-EP* AAC active-low power-OK indicator (POK), an active-low USB input detection output (USBPWR) on the MAX8804Y/ *EP = Exposed paddle.

The MAX8804V has 120mA, 140mA, 180mA, and 200mA CHG top-off threshold settings, while the Typical Application Circuit MAX8804W/MAX8804Y/MAX8804Z have 70mA, 80mA, 90mA, and 100mA. +3.3V The MAX8804V/MAX8804W/MAX8804Y/MAX8804Z accept a 4.15V to 30V DC source voltage or a 4.15V to 16V USB input voltage, but disable charging when AC either input voltage exceeds 7.5V to protect against DC ADAPTER unqualified or faulty input sources. The MAX8804V/ MAX8804V CHG 1F MAX8804W MAX8804W/MAX8804Y/MAX8804Z operate over the GND MAX8804Y POK extended temperature range (-40C to +85C) and are MAX8804Z available in a tiny 8-pin thermally enhanced 2mm x USB USB <USBPWR> PORT 3mm TDFN package.
