Introduction
The MIC1232MY is a member of the MIC Supervisors family from Microchip Technology. It is a supervisor powered by 5V or 3.3V supply and is designed for portable, low power applications that require robust, accurate, and low-cost system reset control. It has an operating voltage range of 2.25V, a quiescent current consumption of just 10nA, and a fast reset propagation delay of just 200µs. Additionally, this supervisor features adjustable reset thresholds and helps reduce system reset time by monitoring and controlling system power sequencing. In general, it is well-suited to meet the various power sequencing needs of system reliability and accuracy.

Application Field
The MIC1232MY is a versatile, low-power and low-cost supervisor solution. It can be used in many applications where system reset control is required, such as in portable digital and communication equipment, industrial control systems, and battery-powered devices. This supervisor is best suited for applications that require robust yet precise reset control. It is also well-suited for portable, power-sensitive systems as it has an extremely low quiescent current of just 10nA.

Working Principle
The MIC1232MY supervisor works by monitoring Vdd for any faults or low or high voltage conditions. When Vdd falls below the reset threshold voltage, an open-drain reset output is asserted. When Vdd returns to an appropriate level and is above the reset threshold voltage, the reset output is de-asserted. This supervisor is designed to minimize system reset time and ensure consistent system power sequencing. Additionally, its adjustable reset threshold leverages the benefit of Microchip’s patented Power Manager II architecture, allowing precise reset timing control.

Conclusion
The MIC1232MY is a low-power and low-cost supervisor solution that is well-suited for applications that require precise system reset control. It features an adjustable reset threshold, an ultra-low quiescent current of just 10nA, and a fast reset propagation delay of just 200µs. Additionally, its patented Power Manager II architecture helps reduce system reset time by accurately monitoring and controlling system power sequencing. In general, the MIC1232MY is a great solution for any system requiring reset control and power sequencing in a low-power and low-cost system.
