MOTOROLA ANALOG IC DEVICE DATA
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.
