Supervisors

Supervisors Power management integrated circuit (PMIC) are electronic components used to monitor and control system power. They are commonly used in microcontroller-based systems to ensure proper system startup, operation, and shutdown.

Supervisors PMICs provide several functions to ensure reliable power management, including:

Power-on Reset (POR): Generates a reset signal when the power supply voltage reaches a stable level, ensuring proper system startup.

Brownout Detect (BOD): Monitors the power supply voltage and generates a reset signal if the voltage falls below a specified threshold.

Watchdog Timer (WDT): Monitors the operation of system software and generates a reset signal if the software does not respond within a set time.

Overvoltage Protection: Protects the system from damage by shutting down the power supply if the voltage exceeds safe limits.

Undervoltage Lockout (UVLO): Prevents system operation when the power supply voltage is too low, which could cause damage or data corruption.

Supervisors PMICs are critical to ensuring the proper and reliable operation of electronic systems. Manufacturers that produce supervisors PMICs include Maxim Integrated, Analog Devices, Texas Instruments, and ON Semiconductor.
