DC Charging
The MAX8804V/MAX8804W/MAX8804Y/MAX8804Z are
designed to charge a single-cell Li+ battery from a DC
source voltage between 4.15V and 7V and withstand
up to 30V maximum input voltage. The charge current
and top-off threshold are programmed with the SET
input.
*POK = LOW WHEN V IN > V OVP
USB Charging
The MAX8804V/MAX8804W/MAX8804Y/MAX8804Z
contain a USB input that allows operation from a USB port
with voltages between 4.15V and 7V and can withstand
up to 16V maximum input voltage. Pulsing SET allows
programming a 95mA, 380mA, or 475mA maximum
charging current when using the USB input.
