MIC845 Datasheet (Micrel Semiconductor) - Micro-Power Comparator/ Battery Monitor

MIC845, Micro-Power Comparator/ Battery Monitor

The MIC845 is a precision micro-power voltage comparator with an on-chip 2.55V reference voltage source.

Intended for voltage monitoring 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 voltag

MIC845 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
