MC33164DM-5R2G Supervisors, by definition, are integrated circuits responsible for monitoring and managing the power supply of various products, protecting it from over and under voltage situations, as well as other electrical hazards. The MC33164DM-5R2G is a Supervisors and Voltage Monitor type device from ON Semiconductor with an integrated threshold voltage detector, and comes in an economical 8-pin SOIC package. It is highly efficient and robust against voltages, and designed for low-power applications.

The MC33164DM-5R2G is mainly used in automotive systems, power-management systems, and also in electrical and electronic equipment for controlling, monitoring and protecting the power supply. Its main function is to detect and monitor certain thresholds in the power supply to ensure that the supply voltage is within the permissible range. It is incorporated into many systems like electric motors, batteries and solar systems as it can withstand extreme temperatures and also provides temperature compensation to improve accuracy.

This Supervisors and Voltage Monitor type device from ON Semiconductor has integrated a threshold voltage detector, powered by a 3V to 6V supply voltage, and ranges from a -45V to +55V absolute maximum rating. It has a high-accuracy and wide input voltage range of 0V to 10V, and contains an internal voltage reference of +2.5V. The external resistor can be used to adjust this voltage reference for higher accuracy.

Its integrated threshold detect circuit functions as a comparator, which can be programmed to detect a specific Reference Voltage (RV). This RV is programmed through an external series resistor and by a resistive divider. The MC33164DM-5R2G is also capable of detecting any positive or negative over/under voltage, when the voltage exceeds the user-determined reference voltage.

The internal hysteresis circuit helps in producing accurate trip-points by preventing any false triggering. In addition, this Supervisors and Voltage Monitor type device incorporates a serial data interface and a status output pin, to indicate the status of the ‘power-on’ or ‘power-off’ conditions. The hysteresis and trip-point values can be programmed through the serial data input, making it very convenient for any application.

The MC33164DM-5R2G also provides a programmable timer, which is used to time-out any voltage faults and maintain the power-state of the system, after the fault is cleared. This timer is also programmable through the serial data interface, and can be set to time-out from less than 1ms to up to 800ms.

In addition to its capabilities of detecting over/under voltage and controlling power-state, the MC33164DM-5R2G also helps in reducing the input supply power consumption, by controlling the ‘wake up’ and ‘sleep’ modes. This helps in saving power and improving the overall efficiency of the system.

The MC33164DM-5R2G is a highly efficient and reliable Supervisor and Voltage Monitor type device, and comes in an industry-standard 8-pin SOIC package. It is suitable for automotive and power-management systems, and also for any system involving controlling, monitoring and protecting the power supply. This Supervisors and Voltage Monitor type device is a great addition to space-limited applications, and helps in increasing the overall performance and efficiency of the system.
