Description

The MC34161/MC33161 are universal voltage monitors intended for use in a wide variety of voltage sensing applications. MC34161/MC33161 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 MC34161/MC33161 to be fully functional is 2.0 V for positive voltage sensing and 4.0 V for negative voltage sensing.
