Power management integrated circuits (PMICs) are integrated circuits used in electronics systems to maximize system battery life. In particular, PMICs control power supply and regulation of power. Supervisors are a subclass of PMIC that focus specifically on monitoring status, providing system reset, and alerting when unwanted conditions occur. The MAX6463UK42+T supervisor is one example of a PMIC supervisor.

The MAX6463UK42+T supervisor is designed for embedded microcontroller systems and pulse-width-modulated (PWM) applications used in consumer, automotive, industrial and other consumer electronics applications requiring an extremely low supply current of 0.85uA. The device is designed to provide system reset and monitoring functions when constructed with an external reset threshold. Additionally, the device integrates a watchdog timer with an adjustable reset timeout. The reset threshold and watchdog timer settings can be programmed in the device with a simple two-wire command interface.

The MAX6463UK42+T supervisor contains a reset generator and supply voltage monitor, adjustable watchdog timer and interface circuitry that can detect a PWM-modulated signal on any of the three inputs. The watchdog timer can be set to generate a reset pulse with a timeout of up to 125ms, while the reset threshold can be set to generate a reset pulse when the supply voltage falls below a programmable minimum level. The device can be programmed with a simple two-wire I2C interface.

The most common application field for the MAX6463UK42+T supervisor is consumer, automotive, industrial and other consumer electronics applications that require an extremely low supply current. The device can be used to monitor the supply voltage in consumer electronics, and can be used to protect microcontroller systems from over-voltage damage in automotive applications. The device can also be used to provide reset and watchdog timer functions in a variety of consumer, industrial and other consumer electronics applications.

The working principle of the MAX6463UK42+T supervisor is relatively simple. When a change occurs in the power signal, the device will detect the change and activate its reset generator. The reset signal will then be sent to the system controller which will be reset if necessary. Additionally, the device incorporates a watchdog timer which can detect the amount of time that the system controller has not sent a signal and will then send a reset signal if it has been too long. The device can also detect an over voltage and activate a reset signal.

In summary, the MAX6463UK42+T supervisor is an extremely low power PMIC supervisor designed for embedded microcontroller systems and PWM applications used in consumer, automotive, industrial and other consumer electronics applications. The device provides system reset and monitoring functions, and integrates a watchdog timer with an adjustable reset timeout. The device can be programmed with a simple two-wire I2C interface, and can detect changes in the power signal and activate its reset generator.
