PMIC - Supervisors

The MAX795SESA+T is a specialized IC designed specifically for PMIC - Supervisors applications, and it is capable of regulating, driving and monitoring relevant devices. Manufactured by Maxim Integrated, MAX795SESA+T is equipped with an array of power supply features like under-voltage protection (UVP) and brown out detection (BOD). In this article, the working principle and application field of MAX795SESA+T are shown.

Working Principle of MAX795SESA+T

MAX795SESA+T has voltage supervisors with precision voltage thresholds and band-gap references. It monitors one or two power rails that are independently programmable with reset logging and window watchdog timer features included. The device features separate active-high and active-low reset outputs and power supply-monitors. The active-low reset “RESET#” signal resets microprocessors or DSPs, as well as other logic circuits, when the voltage falls below the factory-programmed reset-threshold voltage. It utilizes 4 analog comparators to monitor each of the two power supply lines. In the absence of the desired system supply voltage, the comparator’s outputs are SET and RESET# is asserted.

A window-comparator monitors two power-supply lines and keeps reset active if both of them fall below the power-supply select threshold, or if VDD falls above the upper power-supply-select threshold. If VDD falls below the lower power-supply-select threshold, the window-comparator’s output is set and a reset is forced. The open-drain RESET# output is asserted active-low while any of the analog comparator’s outputs is asserted. This makes it possible to monitor any microprocessor or digital logic circuits that require a reset pulse anytime VDD is not within the range of the factory-programmed operating and reset threshold. Moreover, MAX795SESA+T also has an extended temperature range feature to protect against thermal runaway and extreme temperature.

Application Field of MAX795SESA+T

MAX795SESA+T can be used in various areas, such as battery-powered applications, microprocessor power-sup- ply monitoring and portable electronic systems. It is ideal for use in microprocessors and DSPs. It’s extremely low power consumption and extended temperature range are suitable for applications that require extreme reliability and robustness. MAX795SESA+T is also used in portable medical and consumer devices where constant power is needed to ensure that all devices are working properly.

MAX795SESA+T is integrated into a wide range of devices, including automotive, consumer electronics, computer subsystems, power supplies, and more. In particular, MAX795SESA+T is ideal for integrated circuits used in automotive, consumer, mobile, and military applications. As a programmable device, it can be configured to monitor multiple voltages and provides the capability to set hystersis and trip thresholds for reset, power-up, power-down and watch-dog functions. It also features various features, like alert signal, power-on reset inrush current control, watchdog timeout signal and activity Monitor signal.

In conclusion, MAX795SESA+T is a specialized IC used for PMIC - Supervisors. It utilizes 4 analog comparators to monitor each of the two power supply lines and is capable of regulating, driving and monitoring relevant devices. It offers a great selection of features like under-voltage protection (UVP), brown out detection (BOD), reset logging, window watchdog timer, extended temperature range, and more, making it ideal for use in battery-powered applications, microprocessor power-supply monitoring and portable electronic systems.
