Maxim Integrated 

I2C RTC/Supervisor with Trickle Charger

and 512 Bytes EEPROM

ABSOLUTE MAXIMUM RATINGS

Voltage Range on VCC Pin Relative to Ground .....-0.3V to +6.0V

Voltage Range on Inputs Relative

to Ground ...............................................-0.3V to (VCC + 0.3V)

Operating Temperature Range

(noncondensing) .............................................-40°C to +85°C

Storage Temperature Range .............................-55°C to +125°C

Soldering Temperature...........................Refer to the IPC/JEDEC

J-STD-020 Specification.

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.
