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 active high or active low output;
the open-drain output stage is only configured active
high.
Supply current is extremely low (typically 1μA),
making it ideal for portable applications.
MIC845 is supplied in Micrel’s Teeny 5-lead SC-
70 package.
Data sheets and support documentation can be
found on Micrel’s web site at www.micrel.com.
