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.
