Introduction

MC33164DM-3R2G is a type of Power Management Integrated Circuit (PMIC) Supervisors manufactured by ON Semiconductor. It is designed for use in a wide range of applications, such as automotive, extended-temperature industrial and communications applications. A key feature of the MC33164DM-3R2G is its supervisory functions which provide users with a wide range of monitoring and controlling options to ensure reliability and safety. This article will discuss the application field and working principle of the MC33164DM-3R2G.

Application Field

The MC33164DM-3R2G PMIC Supervisors is specifically designed for automotive and industrial applications. This PMIC is ideal for use in Telematics and Infotainment systems, Automotive HVAC systems and Parking Brake Control systems. It is also suitable for use in Industrial Automation and Intelligent Metering, in addition to Thermostats and Timer Controls. The MC33164DM-3R2G is also well suited for applications that require monitoring and automated control of multiple power domains in a single package. It is ideal for use in systems where a single integrated circuit can reduce the chip count and save costs. This PMIC is also suited for use in high-side and low-side switching applications, which can be used to drive loads from a wide input voltage range. This feature makes the MC33164DM-3R2G particularly well suited for automotive and industrial applications, which tend to require the ability to switch between different sources of power or different levels of power supply.

Working Principle

The MC33164DM-3R2G PMIC Supervisors is designed to allow users to monitor and control multiple power domains in a single package. It comprises of two independent power management channels, which can be used to monitor and control a wide range of voltages, current and features. The first channel supports multiple input and output voltage monitoring with the ability to switch between different sources of power or different levels of power supply. This channel also includes reset logic, which can provide a latching or retriggerable reset signal when the input voltage falls below the programmed voltage threshold. The reset signal can be used to reset the system once a certain limit is set and met. The second channel includes an adjustable over- and undervoltage protection, as well as an overtemperature protection system. This channel can be used to establish the desired protection profile for the device, depending on the user’s specific application. This channel also provides protection against overcurrent, short-circuit, ground fault and ESD. In addition to monitoring and controlling multiple power domains, the MC33164DM-3R2G PMIC Supervisors also provides a wide range of monitoring, controlling and fault protection features. The device comes with an integrated watchdog timer, which can be used to detect system hangs, as well as to trigger system reset during emergency situations. Furthermore, the device is equipped with a watchdog pre-triggering feature, which allows the user to set an additional level of threshold voltage protection before resetting the system. The MC33164DM-3R2G PMIC Supervisors also features a comprehensive diagnostic system. This system can be used to identify faults, such as under- and overvoltage, overcurrent and overtemperature, as well as other parameters such as power-off supply and low battery. In addition, the MC33164DM-3R2G also features an energy saving mode, allowing the system to operate with lower power consumption and increased efficiency.

Conclusion

The MC33164DM-3R2G PMIC Supervisors from ON Semiconductor is an ideal solution for a wide range of applications in the automotive and industrial sectors. It provides users with a comprehensive set of monitoring and controlling options, as well as a range of protection and fault detection mechanisms. With its wide range of features and multiple power domains, the MC33164DM-3R2G is a great option for ensuring system reliability and safety in a variety of applications.
