The CAT150169SWI-GT3 is a PMIC supervisor ideal for AC/DC and pure DC voltage regulatoin system. It is also well suited for vertical applications such as modules in a battery system, automotive, home care and industrial equipment. CAT150169SWI-GT3 is built with efficiency, reliability and safety to meet the increasing demands of today\'s digital age. It has the ability to detect overvoltage, brown-out and reset conditions for single cell and multi-cell battery operated electronic equipment. It is also capable of keep track of battery status, voltage and temperature

CAT150169SWI-GT3 is also used in a wide range of consumer electronics such as radio frequency (RF) devices, mobile phones, tablets, digital televisions, set top boxes and gaming consoles. It provides high accuracy voltage measurement and monitoring of the system power supply. By improving the efficiency and reliability of the power supply it reduces system power consumption, resulting in higher performance device.

Working Principle

CAT150169SWI-GT3 is a simple triple voltage supervisor which is usually used as a supervisor/reset in many embedded systems and consumer electronics. The low-cost, ultra-reliable AC/DC supervisor integrates a low-side N-channel MOSFET, a voltage regulator and a voltage supervisor which provides voltage regulation on the Voltaic and the UPS Backup systems.

The device monitors voltages up to 8.5 V for positive and negative overvoltage conditions. The user can adjust the voltage window and the reset time with external resistor divider. On-chip N-channel MOSFET is used as an ON/OFF switch to enable/disable the output voltage from regulator. It provides superior noise immunity and ensures that the system voltage is safe and stable.

The device is also equipped with open drain reset output for signaling reset condition. The output is pulled low whenever reset condition is detected and it will remain low until reset condition is removed. It provides a cost-effective mean of resetting processor whenever there is brown-out or overvoltage conditions.

In addition, the integrated temperature sensor helps in monitoring the health of the operating system. It monitors the temperature of the CAT150169SWI-GT3 and any rise in temperature above permissible levels will cause the device to reset itself. This helps in preventing any damages due to an overheat situation.

CAT150169SWI-GT3 is a reliable and efficient PMIC supervisor suitable for distributed power system. It is designed to provide cost-effective and reliable voltage regulation solution for a variety of applications. Its easy to use configuration makes it an ideal choice for many embedded system applications.
