Universal Voltage Monitors
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 2.54 V reference, and two open collector
outputs capable of sinking in excess of 10 mA. 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 2.0 V 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.
