STM6779TWB6F

A PMIC supervisor is a chip that is designed to watch over the supply voltage and reset the system when the voltage falls outside a predetermined range. The STM6779TWB6F is an integrated linear voltage supervisor with a push-pull-reset active-low output. The IC features internal voltage regulation, power-on reset and voltage monitoring functions. It is designed to provide an accurate monitoring and control of system parameters.

The STM6779TWB6F is suitable for all kinds of industrial, commercial and consumer electronic applications. It is commonly used in smart phones, tablets, digital cameras, game consoles, TVs and Blu-ray players. It is also suitable for home appliances such as washing machines, air conditioners, refrigerators and kitchenware. In automotive, the IC is used to monitor and control fuel injection, windshield wiper motors and antilock braking systems.

The STM6779TWB6F has an internal voltage reference and comparator circuit, which can detect whether an input power supply voltage is within a predefined range. The supervisor monitors a 1.6V - 8.8V voltage range with a 0.5% accuracy level. The board can detect 5V and 12V power rails, as well as battery backup systems and solar cells. The IC supports cycles to detect power failure on a power rail, which is helpful for system power management.

The STM6779TWB6F also has special protection functions, including cycle-by-cycle over-voltage protection, under-voltage lockout protection, over-current and thermal protection. The IC also features low dropout voltage, low quiescent current and low output pin capacitance. The IC also supports active-low reset and active-high reset and offers multiple reset delay generators.

The STM6779TWB6F works in two modes: an active mode and a standby mode. The active mode continuously monitors the input voltage, while the standby mode powers down the system when the voltage falls outside the predetermined range. In the standby mode, the system is reset when the voltage is restored to normal. The internal delay time can be adjusted by an external resistor, so the system can determine how long the voltage is allowed to be outside the normal range before resetting.

The STM6779TWB6F is ideal for a variety of applications such as automotive, industrial, telecommunications, consumer electronics and the military. The IC is reliable, cost effective and power efficient. Its high accuracy, low power consumption, standby mode and reset indications provide extra protection and make it suitable for a wide range of applications.
