Hot-selling and scarce MAX6394US310D3+T High-Accuracy μP Reset Circuit SOT23-4 spot stock

Product Descriptions

The  MAX6394  low-power  CMOS  microprocessor  (μP) supervisory circuit is designed to monitor power supplies inμP and digital systems. It offers excellent circuit reliability by providing 1%accurate thresholds over temperature and by eliminating external components and adjustments. The MAX6394 also provides a debounced manual reset input. 

This device performs a single function: it asserts a reset signal whenever the V CC supply voltage falls  below a preset threshold or whenever manual reset is asserted. RESET remains asserted for an internally programmed interval (reset timeout period) after VCC has risen above the reset threshold or manual reset is deasserted. The MAX6394’s open-drain RESET output can be pulled up to a voltage higher than V CC.

The MAX6394 comes with factory-trimmed reset threshold voltages from  2.4V to 4.8V.  Preset timeout  periods  of0.7ms, 14ms, 105ms, and 826ms are also available. The device comes in a SOT143 package.
