MAX6770TAVD3+T

PMIC - Supervisors refer to the power management integrated circuits (PMICs) designed to alert the system processor when the power supply voltage exceeds or drops below pre-defined thresholds. The MAX6770TAVD3+T is a fully integrated PMIC - Supervisor which offers multiple protection functions to efficiently monitor and protect the system. It includes two threshold voltage detect circuits and one output RESET\ interrupt circuit, as well as extended temperature range and 45μs watchdog timer.

The MAX6770TAVD3+T not only relates to battery affairs with its integrated debounce logic, but also with its voltage detection feature. The voltage detection feature is a power management tool that monitors the system’s main supply voltage for under- or over-voltage conditions. It helps to ensure the system’s line power is within its specified voltage limits, which can prevent potential damage to the system due to under-voltage operation or over-voltage events.

The primary application field of the MAX6770TAVD3+T is the system voltage supply monitoring. It helps to prevent over or under voltage events, which can be caused by electrical spikes, electro-static discharges, AC power losses, etc. Additionally, it provides a means to alert the system processor when the main supply voltage dips outside of the pre-defined thresholds and take appropriate countermeasures to minimize system damages. It is also used for supply voltage monitoring in high end multicore embedded systems.

The basic working principle of the MAX6770TAVD3+T is quite simple. It monitors the system’s main supply voltage, and if it detects that the voltage has fallen or risen outside of the pre-defined thresholds, it will assert an output as an alert signal to alert the system processor to take action. This output signal can be any of a variety of signals, depending on the application, including an interrupt, a reset signal, or a non-maskable interrupt. The MAX6770TAVD3+T also has a 45μs watchdog timer, which if enabled can assert the reset signal when it times out.

The MAX6770TAVD3+T from Maxim Integrated is a fully integrated PMIC supervisor and voltage detection solution. It helps to protect the system from over and under voltage events, as well as monitor the system’s main supply voltage for under- or over-voltage conditions. It is perfect for use in embedded systems, and its output signals can be configured to alert the system processor when the main supply voltage rises or falls outside of the pre-defined thresholds.
