Power management integrated circuits (PMICs) are essential in modern electronic devices, providing efficient and cost-effective solutions to manage electrical power and control circuit parameters. PMICs also provide an optimized solution to maximize battery runtime in portable devices. Supervisors are one subset of PMICs that provide system monitoring, fault detection, and protection functions, and the MAX6323BUT26-T is an example of such a supervisor.

The MAX6323BUT26-T is a voltage supervisor designed for system reset and power-on reset applications. Depending on the application, it can be used as a single reset supervisor or as a dual reset manager with two integrated circuits. The MAX6323BUT26-T features a high voltage input range from 1.8V to 6.2V, as well as a low voltage input range from 1.1V to 4V. It also includes a reset timer for delaying the reset output for desired time intervals or for providing sufficient time for the system to stabilize after device start-up or power-up.

In terms of system reset, the MAX6323BUT26-T can provide the reset pulse width of 2ms once the power is cut off from its input. This ensures that the system will be reset and disabled before the power is completely lost. This feature is also useful in preventing sudden power spikes that can cause system instability. Additionally, the MAX6323BUT26-T is designed to provide a reset pulse width of 1ms when the input voltage exceeds the general operating threshold voltage.

In terms of powering on the system, the MAX6323BUT26-T provides the reset output pulse width of 2ms after the supply voltage has stabilized. This feature prevents the system from running before the system supply voltage has had sufficient time to become stable. This is especially important for modern microprocessor-based systems that are vulnerable to sudden power spikes caused by power-on reset.

Apart from its reset features, the MAX6323BUT26-T also features an active-high RESETB pin that can be used to control the reset output. This pin can be used to disable the reset output or to trigger a reset event. Additionally, this pin can be used to disable the reset output in the event of a power-on reset. This is especially useful for microprocessor-based systems that require the system to be reset before the power-on reset is applied.

The MAX6323BUT26-T also features an integrated temperature sensor that can be used to monitor device temperature and detect thermal runaway. This feature is important for systems that rely on the device operating temperature for optimal performance. Additionally, this feature allows the device to be reset in the event of an over-temperature condition. This ensures that the system will not be subjected to high temperatures and reduce its lifetime.

In summary, the MAX6323BUT26-T is an integrated supervisor designed for reset and power-on reset applications. This IC offers an integrated reset timer, reset output pulse width control, active-high RESETB pin, and an integrated temperature sensor for system monitoring, fault detection, and protection. The MAX6323BUT26-T is a cost-effective solution for managing electrical power and control circuit parameters as well as maximizing battery runtime in portable devices.
