ONSEMI MC33161DG Voltage Monitor

The MC33161 is a versatile voltage monitoring device designed for a wide range of voltage sensing applications in industrial and automotive environments. It features two comparator channels with hysteresis, a Mode Select input for configuring over, under, and window detection of positive and negative voltages, and a pinned out 2.54 V reference with short circuit protection. The device operates fully at as low as 2.0 V for positive sensing and 4.0 V for negative sensing. Its open collector outputs provide enhanced flexibility for system integration, making it ideal for fault detection, power management, and automation systems.
