MIC845 Micro-Power Comparator / Battery Monitor General Description 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 voltages with its high input impedance CMOS input.
The MIC845 incorporates a voltage reference and comparator with fixed internal hysteresis.
When the 2.
55V internal threshold is crossed, the output switches polarity.
MIC845 is available with a push-pull or open-drain output stage.
The push-pull output stage is configured for both acti...
