MIC2778 Description
The MIC2778 is a voltage monitor uniquely designed to detect two separate voltage thresholds bined 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.
MIC2778 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
MIC2778 Applications
- Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices
