It is suitable for applications such as over voltage and over current protection, battery protection, and system power supply reset. This article will discuss the applications and working principles of the MC33164DM.

MC33164DM Application Fields

The MC33164DM is a supervisor that is suitable for applications such as over voltage and over current protection, battery protection, and system power supply reset. This part is specifically designed to fit applications that require low-voltage operation, low quiescent current, and accuracy. It is available in a small SOT-23 package and comes with a wide voltage range and low typical quiescent current of only 130 nA. It can also withstand rapid input voltage excursions and has an adjustable reset threshold. The wide input voltage range of the device (2.0 to 5.5 V) allows the device to be used in a wide variety of applications, ranging from battery operated applications to low voltage systems.

MC33164DM Working Principle

The MC33164DM features an input that is configured to compare the input voltage with a reference and trigger the reset output when the input voltage is outside of the set boundaries. In normal operation, when the input voltage is within the band, the reset output is in a high impedance state, indicating that the supervisor is operating normally. When the input voltage is outside of the acceptable band, the reset output switches to a low state, thus notifying the system that an over voltage or over current state has been reached. The device also features a band gap reference and a hysteresis programmable by a resistor. The accuracy of the device is ensured by the use of a bandgap reference, which provides a more stable reference voltage across temperature and supply variations.

Conclusion

In conclusion, the MC33164DM is a supervisor that is suitable for applications such as over voltage and over current protection, battery protection, and system power supply reset. It is available in a small SOT-23 package and comes with a wide voltage range and low typical quiescent current of only 130 nA. It is designed to offer high accuracy, low quiescent current, and low voltage operation and is a great choice for applications that require these features. Its working principle is based on an input that is configured to compare the input voltage with a reference and trigger the reset output when the input voltage is outside of the set boundaries.
