MAX6466UK29+T is a highly reliable, low-cost supervisor integrated circuit designed to monitor power supplies, as well as alert host microcontrollers/microprocessors when one or more voltages are out of spec. When a voltage is out of spec, the supervisor main output (MOUT) is driven low, informing the host of the event.

MAX6466UK29+T is categorized as a Supervisory IC (PMIC - Supervisors), which are broadly defined devices used to safely manage power system operations by monitoring power supply voltages, microcontroller/microprocessor operation, system startup/shutdown, brownout conditions, and other variables. PMIC devices are used in high-reliability systems, such as medical devices and automotive applications, to protect against hazardous malfunctions.

The MAX6466UK29+T has a variety of application fields. It can be used to provide automatic reset signaling in (1) automotive systems, (2) data communications, (3) networking systems, (4) industrial and IoT applications, (5) LED displays and lighting, (6) computer peripherals, and (7) consumer electronics. This device is designed to protect against overvoltages, brownouts, and power supply sequencing issues, ensuring reliable system operation.

The working prinicple behind the MAX6466UK29+T is fairly straightforward. The supervisor monitors two or four input supplies of up to 18V, and has one main output (MOUT) pin. When all of the supply voltages are above the rising or falling threshold value, the MOUT pin is driven high. If any of the supply voltages go below the falling or rising threshold, the MOUT pin is driven low, informing the host of the event.

The device also includes an external reset time-out (EXT), which resets the MOUT pin if a valid power-on reset (POR) signal is not detected. The supervisor uses an internal slow-start-up circuit and has hysteresis thresholds to prevent unintentional reset during power supply sequencing or brownout conditions.

The MAX6466UK29+T also features a master reset output (MRESET) that provides a true hardware reset to the system in the event of a critical power supply failure. The MRESET output has a built-in pull-up resistor and toggle flip-flop to ensure a proper level for reset. The reset output is independent of the MOUT pin, and is reset to high when the power supply voltages are valid.

The MAX6466UK29+T is a reliable, highly configurable, and low-cost power management solution that can be used in a wide variety of applications. With its accurate supply voltage monitoring, reset capabilities, and low-standby current consumption, it is an essential building block in most high-reliability systems.
