PMIC, or power management integrated circuits, are a type of integrated circuit that control the power input and output in an electronic device.

One particular type of PMIC is supervisors, which control the powerup, reset, enable, and suspend functions of an electronic device. A common example of a supervisor is the MIC6315-31D2UY-TR.

Application Field

The MIC6315-31D2UY-TR supervisor is most commonly used in low-power, portable applications such as mobile phones, personal digital assistants, and notebook computers. It is a single-channel, 3 to 36V supervisor with fixed delay and digitally adjustable reset thresholds, providing accurate reset control when used with a digital delay control.

The low power operation of the MIC6315-31D2UY-TR makes it well suited for use with battery applications where battery drain is a concern. Its wide voltage range and low input current makes it an ideal choice for applications where space and power are limited.

Working Principle

The MIC6315-31D2UY-TR is a 3 to 36V single-channel supervisor that monitors power input and, upon detection of low power or loss of power, will generate an appropriately timed reset. The delay time of the reset signal is adjustable via a simple analog voltage control, allowing for a wide range of reset timings.

The MIC6315-31D2UY-TR derives its power input from the VDD supply and can support input voltage levels of 3.3 to 36V. The low input current of the IC and the low quiescent current make it an effective choice for battery or other low power applications. Additionally, the IC is designed to be tolerant to supply voltage transients and has protection from overvoltage and reverse polarity.

The MIC6315-31D2UY-TR utilizes a series of logic pins for control and status. These pins provide a logic signal to the microcontroller or logic circuit indicating the status of the power to the IC. Additionally, these pins can be used to configure reset thresholds and latch off detections.

The reset signal is generated by a timer circuit utilizing an RC network. This timer circuit can be configured to generate a reset immediately, once or twice, or on detection of an input line change. The MIC6315-31D2UY-TR also supports a watchdog timeout reset, allowing the microcontroller or logic circuit to reset the IC whenever desired.

Conclusion

The MIC6315-31D2UY-TR is an ideal supervisor for low-power, portable applications. The wide voltage range and low input current make it well suited for batter-powered solutions. Additionally, the adjustable reset timings and protections from overvoltage and reverse polarity make it an ideal choice for a range of portable applications.
