The MC34161/MC33161 are universal voltage monitors
intended for use in a wide variety of voltage sensing
applications. These devices offer the circuit designer
an economical solution for positive and negative voltage
detection. The circuit consists of two comparator channels
each with hysteresis, a unique Mode Select Input for channel
programming,a pinned out 2.54V reference,and two open collector
outputs capable of sinking in excess of 10mA. Each comparator
channel can be configured as either inverting or noninverting
by the Mode Select Input. This allows over, under, and window
detection of positive and negative voltages. The minimum supply
voltage needed for these devices to be fully functional is 2.0V
for positive voltage sensing and 4.0 V for negative voltage sensing.
Applications include direct monitoring of positive and negative
voltages used in appliance, automotive, consumer, and industrial
equipment.
