Power management integrated circuits (PMICs) are widely used in the modern electronics industry, offering significant benefits for engineers who, for example, must manage the complexities of power-sensitive designs, reduce the number of components needed, and improve reliability and performance.

Within the broad field of power management integrated circuits are “supervisors,” which are devices specifically designed to monitor and protect digital circuits from error or excessive power conditions and to support brown-out reset, or BOR, conditions.

Often, the application and working principles of the supervisors are implemented in Integrated Circuits (ICs). Of those, MAX6865UK36D4S+T is one such device.

MAX6865UK36D4S+T is a high-voltage, low-power supervisor IC with reset and watchdog features. It includes an internal voltage detector that monitors power supplies up to 12V, and it also features dual power-on reset (POR) and a watchdog timer to detect errors, whether occurring internally or externally.

The POR feature generates an internal timeout that is useful for setting up a board’s reset sequence. In the event of a brown-out, loss of power, or power supply overshoot, the POR asserts a reset to the processor, allowing the system to initialize properly.

The other reset feature of MAX6865UK36D4S+T is the watchdog timer. This non-maskable interrupt (NMI) monitors conditions in the system, such as machine cycles, instruction cycles, and critical variable changes, and can generate a reset if it detects any critical conditions.

It also offers a BOR trigger feature, which allows the MAX6865UK36D4S+T to detect even very low-voltage conditions, compared to a regular POR.

The main applications of MAX6865UK36D4S+T include battery-operated portable systems, point-of-sale (POS) terminals, and internet protocol (IP) set-top boxes. Additionally, it can be used in distributed telemetry, Ethernet switches, automotive systems, and LED driver systems.

MAX6865UK36D4S+T is an advanced IC for use in highly sensitive power applications. Its powerful combination of POR, BOR, and watchdog timer enables it to detect and protect the system from a wide range of errors, resulting in improved system reliability and performance.
