MIC2778 Overview
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.
Key Features
- Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices
- Independently adjustable high- and low-voltage thresholds
- Internal logic prevents battery-voltage-fluctuation chatter
- High ± 2% voltage threshold accuracy; 1% available
- Built in 140ms (minimum) delay deglitches output
- Extremely low 1µA typical supply current
- For applications not requiring built-in delay, see MIC833
- Immune to brief power supply transients
- 5-lead SOT-23 package
