ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VCC = +4.75V to +5.5V for MAX81_L, VCC = +4.5V to +5.5V for MAX81_M, VBATT = 2.8V, TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25°C.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: The input voltage limits on PFI and WDI may be exceeded (up to 12V VIN) if the current into these pins is limited to less
than 10mA.
