PMIC supervisors are powerful devices designed to provide power management solutions to a wide range of electronic systems. The MIC2755YMM is a supervisor device from Microchip Technology, and is suitable for applications that require precise regulation and control of power. It integrates three supervisory functions: reset monitoring/pre-settable power-on delay, system voltage detect, and watchdog timer.

The MIC2755YMM is a precise, low power, and feature-rich 4-pin device that is available in an Automotive qualified version. The device provides multiple functional protection, such as overvoltage, undervoltage and overcurrent protection, which enables an electrical system to remain safe in the event of any fault or interference.

The MIC2755YMM can be used in a variety of critical applications, including automotive, industrial, and consumer products. The device features a relatively low operating voltage of 1.8V to 5.5V, which makes it suitable for use in low-voltage systems. Additionally, the device comes with a 2.6V to 5.5V VDDinput range, which allows for efficient monitoring of system power rails with low voltage thresholds.

The reset delay and pre-settable power-on delay functions are the main features of the MIC2755YMM. The reset delay ensures that the device remains in reset until the voltage threshold is reached and supply voltage is stable. The pre-settable power-on delay is used to reduce power-up time of the system by controlling the timing of reset signals. The device also has a window watchdog timer that can be programmed for a selected time period. The watchdog timer forces the system to reset if the communication between the device and the system is not received in the predetermined time period.

The MIC2755YMM also has an integrated overvoltage detector, which monitors the system voltage and provides an alert or reset if the voltage exceeds the pre-programmed threshold. The undervoltage protection is used to keep the system from operating if the voltage falls below a pre-programmed threshold. The device also provides thermal shutdown protection and a programmable overcurrent threshold that can be used to shut down a system if the current into the device exceeds its set threshold.

The MIC2755YMM is suitable for use in a variety of high-performance applications. It is programmable, supports high-power requirements, and has a small footprint. The device also features an active low open drain output, which offers flexibility in reset operation. In addition, the device is fully ATE tested to meet high-quality standards.
