ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VCC = 1.2V to 5.5V, TA = -40°C to +85°C, unless otherwise specified. Typical values are at VCC = 2.5V, TA = +25°C.) (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.
VCC, Open-Drain RESET to GND ..........................-0.3V to +6.0V
MR, Push-Pull RESET, RESET,
WDI, CT, I.C............................................-0.3V to (VCC + 0.3V)
Input Current, Output Current (all pins)............................±20mA
Continuous Power Dissipation (TA = +70°C)
5-Pin SOT23 (derate 7.1mW/°C above +70°C)............571mW
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature .....................................................+150°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
