ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

(VCC = VCC(MIN) to VCC(MAX), TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)

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.

VBATT, VCC to GND ...............................................-0.3V to +6.0V

All Other Pins to GND ................................-0.3V to (VCC + 0.3V)

All Other Pins to GND ............................-0.3V to (VBATT + 0.3V)

Input Currents

VCC ..................................................................................200mA

VBATT .................................................................................20mA

GND ....................................................................................20mA

All Other Pins ....................................................................±20mA

Output Currents

VOUT Continuous ..........................................................200mA
