MC34161DR2

The MC34161DR2 is a versatile multi-voltage supervisor IC manufactured by On Semiconductor. Designed for a wide range of voltage sensing applications, it offers two comparator channels with hysteresis and a unique mode select input for channel programming. This device provides economical solutions for both positive and negative voltage detection.

Key electrical characteristics include a pinned-out 2.54 V reference with current limit protection and open collector outputs capable of sinking in excess of 10 mA. The minimum supply voltage required for full functionality is 2.0 V for positive voltage sensing and 4.0 V for negative voltage sensing. The input voltage range for comparators is -1.0 V to +40 V, with a maximum output voltage of 40 V.

This supervisor is suitable for over, under, and window voltage detection. Each comparator channel can be configured as either inverting or non-inverting via the mode select input. The MC34161DR2 is supplied in an 8-SOIC package and is designed for surface mount applications. Its operating temperature range is 0°C to 70°C (TA).

Applications for the MC34161DR2 include direct monitoring of positive and negative voltages in appliance, automotive, consumer, and industrial equipment. Its flexibility and robust design make it a reliable choice for critical voltage monitoring tasks.
