Description: Micro-Power Comparator/ Battery Monitor

Features

* Extremely low 1µA supply current (typical) 2.55V on chip reference ±2% voltage threshold accuracy Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices
* Open-drain output can be pulled up to 6V regardless of supply voltage

Applications

* the MIC845 can be used with an external resistor divider to detect a wide range of voltages, or without external resistors to directly monitor voltages with its high input impedance CMOS input. The MIC845 incorporates a voltage reference and comparator with fixed internal hysteresis. When the 2.55V
