Power Management Integrated Circuits (PMICs) are specialized semiconductors that control and optimize a system\'s power resources. Supervisors are PMICs that monitor power supply voltages and generate system-level reset signals under extreme conditions. In this article, we\'ll discuss the application field and working principle of the MIC810TYC3-TR, a system-level Supervisory IC.

Uses of MIC810TYC3-TR

The MIC810TYC3-TR, designed and manufactured by Micrel, Inc., is a low-frequency supervisor with an adjustable, system-level reset window. This device is ideal for use with processors and microcontrollers, such as the Microchip PIC16F87xA family, or with low-power, 3V or low-power 5V application designs.

The MIC810TYC3-TR is a distinctively robust Supervisory IC, combining features such as on-chip voltage reference and optional push button reset input. Additionally, a low-calibration input resistance, together with low-hysteresis (±3mV) reset-detection window and accurate time delay guarantees high reliability.

This device also features one critical output (RESET) with a reset assertion voltage of 1.6V typical, allowing for an accurate reset on a single supply. The MIC810TYC3-TR is designed to provide high-frequency reset interrupts and also support selectable redirection of the reset signal to an alternate pin, making it perfect for designs with a limited number of pins.

Other features of this Supervisory IC include a short-duration open drain performance, programmable reset delay, interrupt on System Reset (IRQ) output, and an external capacitor-programmable reset timeout.

Working Principle

The MIC810TYC3-TR provides a low-noise reset output signal which is generated when the system voltage falls below a predetermined threshold. To accurately detect small changes in input voltage, the MIC810TYC3-TR has an internal voltage reference. This reference voltage is compared with the voltage of the monitored power supply rail, when the monitored voltage falls below the reference, a reset signal is triggered.

The MIC810TYC3-TR features a programmable reset-delay timing and a reset timeout function. The delay timing is generally determined by the value of an external capacitor and the output signal is generated only after the delay. The reset timeout is enabled if an external capacitor is connected and the reset signal will be generated when the reset timeout period has expired.

In addition to the programmable delay and reset timeout capability, the MIC810TYC3-TR also provides an optional push button reset signal. This signal can be used to manually reset the device and is applied with a steady 1.6V output.

The MIC810TYC3-TR is designed to provide up to 200mA of current drive, which is sufficient to pull either the input low or high. For the reset output, a low-impedance output drive of 1.6V is required, ensuring that the reset signal is generated at the correct level.

Conclusion

The MIC810TYC3-TR is a system-level Supervisory IC designed by Micrel, Inc. It is capable of monitoring power supply voltages and generating a system-level reset signal under extreme conditions. This device is an ideal option for processor and microcontroller designs that require robust, low-frequency Supervisory circuitry. In addition to system-level reset functions, the MIC810TYC3-TR also provides a programmable reset delay and reset timeout, as well as an optional push button reset input.
