General Description
The MAX8804V/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 overvolt-
age protection (OVP), and eliminate the reverse-block-
ing Schottky diode.
The MAX8804V/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. Proprietary thermal-regulation cir-
cuitry limits the die temperature when fast-charging or
while exposed to high ambient temperatures, allowing
maximum charging current without damaging the IC.
The MAX8804V/MAX8804W/MAX8804Y/MAX8804Z
achieve high flexibility by providing an adjustable DC/USB
fast-charge current through a simple single-wire interface

Ordering Information
(SET input). The chargers automatically select between
either a USB or AC adapter input source. The AC adapter
charge current is programmable from 400mA to 700mA in
50mA steps through a serial interface. The USB charge
current is programmable to 95mA, 380mA, or 475mA
through the same interface. Other features include an
active-low battery charging-status indicator ( CHG ), an
active-low power-OK indicator ( POK ), an active-low USB

MAX8804V/MAX8804W.
The MAX8804V has 120mA, 140mA, 180mA, and
200mA CHG top-off threshold settings, while the
MAX8804W/MAX8804Y/MAX8804Z have 70mA, 80mA,
90mA, and 100mA.
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
