Power management integrated circuits (PMICs) are semiconductor devices used to control and regulate the power supplies of various electronic components such as microprocessors and application-specific integrated circuits (ASICs). Within the PMIC family, supervisors are a type of integrated circuit (IC) that monitors the voltages and current supplied to target components. Regarding PMIC supervisors, the ADM1232ARWZ-REEL is a chip designed to sense, regulate, and monitor the output voltage of power management systems.

Specifically, the ADM1232ARWZ-REEL is a programmable AC/DC and DC/DC supervisor IC that can be used to provide overvoltage and undervoltage protection to a variety of system components. It is designed to support a wide input voltage (VIN) range of 3.0V to 38V allowing a broad range of applications. The main application of the ADM1232ARWZ-REEL is in low-power and high-current power supplies for industrial, automotive, and consumer applications.

The chip contains an adjustable reset circuit which provides an active-low reset signal to the host controller under various fault conditions. The reset circuit is triggered by an overvoltage or undervoltage condition on the output of the voltage regulator. In addition, the chip also contains an adjustable watchdog timer which triggers the reset signal when the programmed interval is expired. The interval is set during manufacturing and can be adjusted in accordance with the system requirements.

The ADM1232ARWZ-REEL provides overvoltage protection and programmable undervoltage lockout (UVLO) using an internal comparator. The chip also contains an adjustable low dropout (LDO) voltage detector which is used to detect low voltage conditions and a programmable delay circuit which is used to control the start-up of a power supply. In addition, the chip contains a programmable power-good (PG) indicator which can be used to indicate the health of a system.

The chip has an operating temperature range of -40°C to +125°C and is available in a range of package options including a surface-mount SOT-23 package and a leadless chip carrier (LCC) package. It is also compliant to UL, TUV, and AEC Q100 which makes it suitable for use in a variety of industrial, automotive, and consumer applications.

To summarize, the ADM1232ARWZ-REEL is an adjustable AC/DC and DC/DC supervisor IC designed to provide overvoltage and undervoltage protection to a variety of system components. It contains an adjustable reset circuit, an adjustable watchdog timer, an adjustable low dropout voltage detector, a programmable delay circuit, and a programmable power-good (PG) indicator. The chip is compliant to UL, TUV, and AEC Q100 and is available in a range of package options. It is suitable for use in low-power and high-current power supplies for industrial, automotive, and consumer applications.
