Note 1: Devices are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design

and characterization.

Note 2: VIN refers to the input for the IC. For the MAX8804V/MAX8804W/MAX8804Y/MAX8804Z, VIN is VDC with VUSB = 0V or VUSB

with VDC = 0V.

Note 3: Guaranteed by undervoltage and overvoltage threshold testing. For charge completion, the input voltage must be greater

than 4.28V.

Note 4: This hysteresis is for all charge current except 95mA. In the case of 95mA charge current, voltage-mode to current-mode

detection gives indication of charge mode.
