Micrel
General Description
The MIC2755 is composed of multiple comparators, a reset pulse generator, and logic. It is designed for monitoring the battery supply of portable digital systems, including PDAs and pagers.
FEATUREs
• Optimized for PDAs, pagers and other hand-held devices.
• Detects multiple battery states:
- battery OK
- low battery
- dead battery
• Adjustable voltage thresholds
• High accuracy ±2% voltage thresholds
• Reset generation at power-on (700ms min.)
• Debounced manual reset function
• Internal logic prevents chatter if battery voltage fluctuates
• Extremely low 2µA typical supply current
• I/Os can be pulled above VDD (7V absolute maximum)
• Immune to brief power supply transients
• Low cost
• 8-pin MSOP
