ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VCC = full range, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C and VCC = 3V.) (Note 1)
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.
Terminal Voltage (with respect to GND)
VCC ...........................................................................-0.3V to +6V
RESET, RESET (push-pull) .........................-0.3V to (VCC + 0.3V)
RESET (open drain)..................................................-0.3V to +6V
Input Current (VCC) .............................................................20mA
Output Current (RESET, RESET).........................................20mA
Rate of Rise (VCC) ...........................................................100V/s
Continuous Power Dissipation (TA = +70°C)
3-Pin SC70 (derate 2.7mW/°C above +70°C) ...............174mW
3-Pin SOT23 (derate 4mW/°C above +70°C)................320mW
Operating Temperature Range ...........................-40°C to +85°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
Note 1: Overtemperature limits are guaranteed by design and not production tested.
