The BD5325FVE-TR is classified as a supervisor IC module within the power management integrated circuit (PMIC) family. It is a versatile device used for a variety of applications, primarily in consumer electronics, automotive and industrial applications. The device offers CP-OFF power on/off control for system reset, voltage monitoring/switching, over-current limit, brown-out detection and temperature detection.

The BD5325FVE-TR application field includes consumer electronics, automotive, and industrial applications where system voltage monitoring, voltage switching, CP-OFF control, over-current limit, brown-out detection, and temperature detection functions are required. It is commonly used in mobile phones and other portable hand-held devices, LED displays, and power supplies.

The working principle of the BD5325FVE-TR is based on a highly integrated system power detection and control circuit. The device integrates a Voltage Regulation (VR) chip and a voltage monitor, which can measure the output voltage of the system in multiple ranges. It also includes a Power ON Reset (POR) controller, a CPU supervisor and a unique over-temperature protection circuit.

The Voltage Regulation (VR) chip included in the device supports a wide input range and is capable of regulating an output voltage as low as 1.2V. The power ON Reset (POR) controller is used to maintain the system’s power on and off states, as well as the reset state. It triggers a reset signal if the output voltage goes below the lower limit. The CPU supervisor is responsible for monitoring the supply voltage level and giving a warning if the supply voltage is beyond the set limits.

The device also has an over-temperature protection circuit which protects the system from high temperatures. It triggers a warning signal when the temperature rises beyond the over-temp threshold. The unique feature of this device is that it is equipped with multiple current sensing channels for over-current protection.

In conclusion, the BD5325FVE-TR is a highly integrated system voltage monitor and control IC module from the PMIC family. With features such as overcurrent protection and temperature protection, this device offers superior performance in multiple applications. It is ideal for use in consumer electronics, automotive and industrial applications where system voltage monitoring, CP-OFF control, over-current limit, brown-out detection, and temperature detection functions are required.
