Product Summary
The MAX822SUS-T is a microprocessor supervisory. The MAX822SUS-T provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits. The MAX822SUS-T also provide a power-on reset timeout delay that is pin selectable to 1ms (max), 20ms (min), or 100ms (min). Applications are (1)Bar-Code Scanners; (2)Computers; (3)Controllers; (4)Intelligent Instruments; (5)Critical μP and μC Power Monitoring; (6)Portable/Battery-Powered Equipment.
Parametrics
