A power management integrated circuit (PMIC) supervises, depicts and controls the flow of power between the power source and the electrical applications or system loads. PMICs generally offer a few specific power management functions such as power conversion, power supply management and power sequencing. The MIC2793LH-04VMT-T5 is an example of a PMIC supervisor.

The MIC2793LH-04VMT-T5 is a low-voltage, low-power, single-channel power supervisor with an accurate, adjustable undervoltage threshold and active-high reset output. This supervisor is designed to detect voltages below an adjustable trip point and to produce an active-high reset pulse when the voltage falls below the threshold. The MIC2793LH-04VMT-T5 is capable of providing flexibility and reliability for power management applications.

Application Field

The MIC2793LH-04VMT-T5 is used in a wide variety of portable applications such as industrial devices, car telematics, consumer devices, battery management systems and telecommunications systems. The device offers high accuracy, low power consumption and a small package size, making it ideal for power solutions with restricted power consumption.

Working Principle

The MIC2793LH-04VMT-T5 monitors an input voltage, which issues a reset pulse if the voltage falls below an adjustable trip point voltage. The adjustable trip point voltage can be set using an external resistor. The output reset pulse is active high and includes an internal pull-up so no external pull-up resistor is required. The device offers fast response times, excellent accuracy and noise immunity. It also provides an output disable pin which can be used to immediately disconnect the active-high reset output.

The MIC2793LH-04VMT-T5 is specifically designed to have fast power-up time and low quiescent current. The power-up delay of the device is dependent on the typical monitoring accuracy of the adjustable threshold, the delay time of the reset output and the active-high voltage level after reset. It is also designed for fast power-down time, which ensures that the output is disabled when the input voltage drops below the set threshold voltage.

The MIC2793LH-04VMT-T5 is a robust and efficient power supervisor, offering protection in a wide variety of applications. It provides multiple levels of protection against voltage fluctuations and offers a low power-up delay, resulting in a quick recovery from reset pulses. This device also features a fast power-down time, which ensures that the output is disabled when the input voltage drops below the set threshold voltage. This high-performance PMIC supervisor is an ideal choice for power management solutions.
