PMIC, or power management integrated circuits, are a range of integrated circuits used to manage and regulate power used in electronic devices. They are used to monitor and control power supply voltages, reduce voltage ripple, rectify AC current, and reduce thermal losses generated by power supply circuits. Supervisors, specifically, are used for system power sequencing, power fail detection and reset, and protecting device configurations from corruption. Supervisors are often used in systems that require reliable and safe power sequencing, as well as in systems that need to recover from a power failure.

MAX6734KASVD3+T is a PMIC-Supervisor that is used in systems requiring reliable and safe power sequencing, power fail detection and reset, as well as providing system protection from voltage transient as well as restoring or keeping device functionally or memory even after a power failure. It is intended for use in automotive, industrial, and consumer applications.

The MAX6734KASVD3+T consists of three main components: an integrated voltage detection (IVD) comparator, an internal microprocessor (μP) reset, and an internal power fail comparator

The IVD comparator monitors the power supply or battery supply voltage. It is capable of detecting IVD voltage levels in two different ways. The first is by monitoring the output power supply or battery voltage, and the second is by monitoring the output voltage of the internal voltage regulator (VR). Both methods enable the device to protect the system from damage caused by undervoltage and overvoltage conditions.

The internal microprocessor reset monitors the internal reset line in order to detect any reset conditions due to power failure or other errors. The μP reset is also equipped with a watchdog timer to detect any system crashes and perform a system reset.

The internal power fail comparator monitors the power supply and battery voltage. The comparator is designed to detect any decrease in the supply voltage and trigger a reset in order to prevent system damages caused by power failures.

In order to ensure reliable power sequencing, the MAX6734KASVD3+T includes a clock source and two power supply sequencing pins. The clock source is used for accurate power supply sequencing, and the two power supply sequencing pins are connected to the power source by two output pins. This enables the device to accurately control when power needs to be supplied or shut off and keeps the system from being damaged due to overvoltage or undervoltage conditions.

The MAX6734KASVD3+T is designed to provide system protection and reset functions under a wide range of temperatures. It is capable of operating at temperatures up to +125°C, and is tested and verified to be able to function under these conditions.

The MAX6734KASVD3+T is a reliable and safe power management IC that is perfect for applications requiring reliable power sequencing, power fail detection and reset, and protection from voltage failure conditions. It is designed to work at extreme temperatures, and provides system protection and reset functions.
