The MC33064P-005 is a low voltage supervisor designed to use with low voltage microcontrollers, microprocessors, digital signal processors, and other related integrated circuits. It is designed to provide reliable and accurate detection of low voltage thresholds, providing microprocessor reset and voltage monitor functions. This article explains the application field and working principle of the MC33064P-005.The MC33064P-005 is a low voltage supervisor device, available in a 3-pin SOT23 package. It is specifically designed for use in systems in which the supply voltage (VCC) is below 3.0V, or in cases where it is desired to monitor multiple supply voltages (V1 and V2) at the same time, up to 3.6V. To ensure that the VCC and V1 and V2 remain within their specified voltage levels, the MC33064P-005 offers an integrated monitoring circuit with an accurate trip point. Its output pin (RESET) can be used to reset the microprocessor or other integrated circuits when VCC and/or V1 or V2 drops below its preset level.

The device also provides an open-drain active-high reset output and can also be used to set a low voltage threshold for microprocessor and other circuit operations. The MC33064P-005 is equipped with an adjustable low voltage reset threshold to enable a wide variety of applications. The trip point can be adjusted between 2.95V and 3.37V with an external resistor, and a wide selection of resistor values is available, from 4.7KΩ to 598KΩ. This allows for greater flexibility and allows the MC33064P-005 to be tailored to specific applications.

The main application areas of the MC33064P-005 are in portable electronic equipment and consumer electronics such as cell phones, PDAs, digital cameras and cordless telephones. It is designed to protect against system malfunctions due to low voltage conditions, providing a reliable reset and voltage monitoring solution. It requires minimal external components and is suitable for auto-zeroing and other power-up reset functions. Also, the MC33064P-005 can be used to accurately monitor and detect multiple supply voltages at the same time (V1 and V2).

The working principle of the MC33064P-005 is relatively straightforward. When the supply voltage (VCC) or one of the monitored voltages (V1 and/or V2) drop below the preset trip point voltage, the MC33064P-005 will activate its reset pin (RESET), which will then activate or reset the microprocessor or other integrated circuits. The trip point is adjustable using an external resistor, allowing for a wide range of applications. Once the supply (VCC) is high enough to meet the trip point voltage, the MC33064P-005 will deactivate the reset pin and allow the system to function normally.

In conclusion, the MC33064P-005 is a low voltage supervisor designed to use with low voltage microcontrollers, microprocessors, digital signal processors, and other related integrated circuits. It is designed to provide reliable and accurate detection of low voltage thresholds, providing microprocessor reset and voltage monitor functions. Its main application is in portable electronic equipment and consumer electronics, such as cell phones, PDAs, digital cameras and cordless telephones. Its working principle is based on its adjustable low voltage reset threshold, which enables it to accurately monitor and detect multiple supply voltages at the same time. The MC33064P-005 is a reliable, accurate and cost-effective solution for low voltage protection.
