Power Management Integrated Circuits (PMICs) are a group of integrated circuits which maintain power levels and provide power control functions. Their main purpose is to monitor and maintain power levels in electronic systems. Supervisors, a type of PMIC, are designed to detect and correct power management problems. The MIC2790H-04VD6-TR is one such supervisor.

The MIC2790H-04VD6-TR is a low-voltage supervisor from Microchip Technology. It offers an adjustable voltage threshold, low power consumption and small package size. The MIC2790H-04VD6-TR is designed for and provides protection to 3V and 4V CMOS logic circuits. It monitors power supply voltages in these systems and will report faults or errors if needed. It is available in SC-70 and SOT-23-5 packages.

The MIC2790H-04VD6-TR is suitable as a power supply supervisor in a wide range of applications including microcontrollers, gate drivers and motor drivers. It can also be used in automotive, industrial and consumer applications. It is especially suitable for those applications which require high accuracy and tight tolerance voltage monitoring.

The MIC2790H-04VD6-TR offers an adjustable voltage threshold range from 0.8V to 3.75V. It also features a minimum 200mV hysteresis voltage, low 3uA supply current, and 17ms response to an overvoltage/undervoltage input signal change. It also has an active-low open-drain reset output and an active-low push-pull reset output.

The MIC2790H-04VD6-TR\'s working principle is relatively simple. It measures the voltage at each of its monitored power supply pins. If the measured voltage falls outside of the ACPI specification for the device, then the MIC2790H-04VD6-TR issues an assert at its reset output, signaling that the power supply has gone outside of spec. The MIC2790H-04VD6-TR also provides an active-low push-pull reset output and a low-power active-low open-drain reset output.

Once the power supply is within the ACS specification limits, the MIC2790H-04VD6-TR deasserts the reset output. Furthermore, it features a specified 200mV hysteresis voltage which prevents the reset output from bouncing due to noise or other voltage fluctuation.

In summary, the MIC2790H-04VD6-TR is a low-voltage supervisor designed for 3V and 4V CMOS logic circuits. It can be used in many applications, including microcontrollers, gate drivers and motor drivers, as well as in automotive, industrial and consumer applications. The MIC2790H-04VD6-TR measures the voltage at each of its monitored power supply pins and issues an assert signal if the voltage is outside of the ACPI specification. It also provides an active-lowOpen-drain reset output and a low-power active-low push-pull reset output.
