Introduction

BD5239G-TR is a PMIC (power management integrated circuit) supervisor designed to monitor an external power supply and provide power reset signals and overtime protection. It monitors the AC or DC power supply and provides reset signals to other PMICs and system components when the external power is lost or goes outside the operating range.

Features

BD5239G-TR provides protection and monitoring capabilities to ensure safe operation of external power sources. It features an adjustable over-temperature protection threshold and over-current and over-voltage protection. It also features a programmable power-on reset time and a highly accurate, 2% over-temperature reset margin. All of these features allow for the power supply and other components to be quickly reset, which helps reduce system downtime.

Application Field

BD5239G-TR is designed for use in a variety of applications and products, including consumer electronics, industrial systems, automotive electronics and medical devices. Its monitoring and reset capabilities help ensure safety, performance and stability in these systems. It is also well-suited for use in high-power and high-current systems, where its over-temperature, over-voltage and over-current protection capabilities are particularly beneficial.

Working Principle

BD5239G-TR works by monitoring and managing the power supply. When the external power supply reaches or exceeds a programmable over-voltage threshold, the chip will latch and generate a reset signal. The over-temperature protection feature also helps to protect the system from extreme temperatures. When the temperature in the area or system reaches the over-temperature threshold, the chip will latch and provide a reset signal.The chip also has an adjustable power-on reset time. This allows the system to be reset if the external power source has been lost, or if the external power source is out of range. This helps to ensure that the system remains safe, stable and operational.

Conclusion

BD5239G-TR is a PMIC supervisor designed to provide protection and monitoring capabilities to ensure the safe operation of power supply. Its features make it suitable for use in a variety of applications, such as consumer electronics, industrial systems, automotive electronics and medical devices. Its power monitoring and reset capabilities also help to reduce system downtime.
