MAX817LCPA - Brand New Maxim Integrated Supervisors
-
Description
The MAX817LCPA is a microprocessor (µP) supervisor circuit designed for use in +5V-powered systems. It simplifies power-supply monitoring, battery control, and chip-enable gating in µP systems by reducing the number of components required. It has low supply current (11µA typical) and small package size, making it ideal for portable applications. Other supervisory functions include active-low reset, backup battery switchover, watchdog input, battery freshness seal, and chip-enable gating. It can also ignore fast transients on VCC.
