Voltage Monitor with Adjustable Hysteresis Preliminary Information
General Description
The MIC2778 is a voltage monitor—uniquely designed to detect two separate voltage thresholds—combined with a delay generator and logic.
It is designed for monitoring the battery supply of portable digital systems, particularly PDAs, pagers, and cellular telephones.
High- and low-voltage thresholds can be adjusted independently, allowing for wide hysteresis.
Voltage detection thresholds are accurate to 2%.
If the battery voltage falls below the low-voltage threshold, the output (RST) is asserted and latched, preventing system operation until the battery is replaced or recharged.
