The MAX794ESE+ is a 3V/3.3V microprocessor supervisory circuit in 16 pin NSOIC package. The microprocessor (μP) supervisory circuit will monitor and control the activities of +3V/+3.3V μPs by providing backup-battery switchover. The backup-battery voltage can exceed VCC and permit the use of 3.6V lithium batteries in systems using 3V to 3.3V for VCC. This device is used in embedded controllers, intelligent controllers, battery powered computers.
Supply voltage range is 1.1V to 5.5V
Operating temperature range from -40°C to 85°C
Adjustable reset trip precision supply voltage monitor
Chip enable gating and manual reset input
Reset assertion to VCC = 1V
Battery freshness seal
Uncommitted voltage monitor for power-fail or low-battery warning
Independent watchdog timer (1.6s timeout)
Active-high, push-pull / active low, open-drain reset type with reset threshold of 1.25V
onboard gating of chip-enable signals, 200ms propagation delay
