MAX6858UK16D3+T PMIC Supervisors devices are widely used in many applications to provide power management and protection. The device offers superior protection and management capabilities, including the capability to detect and monitor the supply voltage, detect faults, reset or inhibit continuity over the supply range, and detect overvoltage. It also features self-resetting misfiring protection, adjustable softstart, adjustable brownout detection, adjustable overcurrent protection and temperature monitoring.

The MAX6858UK16D3+T provide cold-start delay and programmable rising-/falling-edge rearmable delayed latched output with open-drain or push-pull output for up to two system reset or power-on reset signals. The rising-/falling-edge delay time is programmable and its reset information includes watchdog timeouts, voltage faults, and overcurrent related faults. Additionally, the MAX6858UK16D3+T provides an open-drain output that indicates that either a system reset or a power-on reset has occurred.

The MAX6858UK16D3+T includes a 16-bit internal register that is used to control the device. The internal register provides the capability to configure the reset thresholds, voltage monitoring, reset types, as well as other device settings, such as SEQUENCING, POR, and TEST IO. This internal register can be configured using a serial interface or via I2C. The serial interface allows the device to be programmed either at power-on or during system operation, while the I2C interface allows the device to be written during system operation.

The working principle of the MAX6858UK16D3+T is based on the fact that it acts as a controller that monitors the supply voltages and redirects power from one source to another, as well as detects and reacts to various types of faults. The device can detect voltage levels, reset or inhibit continuity across its supply range, detect overvoltage and provide a delayed output signal in the event of a fault. Additionally, the device can detect and reset the system after the detection of a watchdog timeout, voltage fault, overcurrent fault, and other types of faults.

The MAX6858UK16D3+T can be used in a variety of applications, including embedded systems, industrial control systems, security systems, home automation, and HVAC (heating, ventilating, and air conditioning) systems. It is suitable for applications that require reliable power supply protection, voltage monitoring and voltage sequencing. The device is also suitable for applications that require fast response times for reset signals, as well as the capability to detect and monitor the supply voltage during system power-up or power-down.

In summary, the MAX6858UK16D3+T PMIC Supervisor is a device that provides superior protection and power management capabilities. It is suitable for a wide range of applications and offers features such as voltage monitoring, voltage sequencing, watchdog timeout detection, overvoltage detection, overcurrent protection, and temperature monitoring. The device is fully programmable via a serial interface or I2C which enables flexibility to tailor the device to specific applications. The device is also capable of resetting the system in the event of a fault, ensuring reliable protection of the system.
