The MAX823SEXK+T is a microprocessor supervisory circuit with watchdog timer and manual reset in 5 pin SC-70 package. This microprocessor's (μP's) reset input starts the μP in a known state and μP supervisory circuit assert a reset to prevent code execution errors during power-up, power-down and brownout conditions. It is specifically designed to ignore fast transients on VCC and significantly improve system reliability, accuracy compared to separate ICs or discrete components.
Supply voltage range is 1.2V to 5.5V
Operating temperature range from -40°C to 85°C
Precision monitoring of +2.5V, +3V, +3.3V and +5V power supplies
Reset threshold voltage is 2.93V
Watchdog input and manual reset input
Fully specified over temperature
Power on reset is 200ms
Reset (complimentary) valid to VCC = 1V
Power supply transient immunity
No external components for watchdog or reset function
