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.

Product Usage
The MC34161P is a precision voltage detector and voltage monitoring integrated circuit (IC). It is used in various applications where voltage levels need to be monitored and specific actions are to be triggered when the voltage falls outside preset thresholds. Some typical circuits that use the MC34161P include:
Power Supply Monitoring Circuits: These circuits monitor the output voltages of power supplies. The MC34161P can detect undervoltage and overvoltage conditions, allowing for protective actions like shutting down the power supply or triggering an alarm.
Battery Monitoring Circuits: It is used in battery-operated devices to ensure the battery voltage remains within safe operating limits. If the battery voltage drops too low, the MC34161P can signal for a battery recharge or device shutdown.
Microcontroller Supervisory Circuits: The MC34161P can be used to monitor the supply voltage of microcontrollers. If the voltage drops below a critical level, it can reset the microcontroller or hold it in a reset state to prevent erratic operation.
Overvoltage Protection Circuits: This type of circuit monitors voltage levels and can disconnect critical components if the voltage exceeds a maximum threshold, protecting the components from damage.
Analog Signal Monitoring: The MC34161P can be used to monitor analog signal levels in various systems, ensuring that the signal remains within desired boundaries.
Industrial Control Systems: These systems often require reliable voltage monitoring to ensure accuracy and safety. The MC34161P can provide the necessary monitoring capabilities.
By integrating the MC34161P in these circuits, designers can ensure that voltage levels are accurately monitored and appropriate actions are taken to maintain system stability and protect components.
