A supervisor IC, also known as a supervisory circuit, is an IC that monitors a variety of parameters in a system, to ensure that the components of the system remain within specific operating parameters and prevent system crash or damage. BD5234G-TR is a supervisor IC designed by ROHM that offers good reliability, accuracy, and stability for system health monitoring. In this article, we will discuss the application field and working principle of the BD5234G-TR supervisor IC, in order to shed light on its further potential use cases.

Application Field

The BD5234G-TR supervisor IC is primarily designed for battery-powered devices and is suitable for use in applications such as smart meters, battery-powered portable medical devices, home healthcare equipment, and industrial IoT devices. It can also be used in automotive systems where system health monitoring and accuracy are required.

The BD5234G-TR offers an array of features in a single package, making it suitable for use in a wide range of applications. It offers a wide range of operating voltage, from 3.0V to 5.5V, and features a high-accuracy voltage detector, low-power voltage detection mode, and an optional power-off reset function. It is capable of detecting up to two supply voltages, with a detection voltage range of 1.6V to 5.5V. In addition, it features an I2C interface, allowing for easy integration with existing systems.

Working Principle

The BD5234G-TR supervisor IC utilizes a resistor-capacitor (RC) circuit to detect voltages for its power supply monitoring functions. When the system power is applied, the circuit is charged to the input voltage. When the system power is disconnected, the capacitor begins to discharge, and when the voltage across the capacitor drops to a set threshold (e.g. 1.6V), the supervisor IC sends a signal to the system to shut down.

The BD5234G-TR supervisor IC also offers a low-power voltage detection mode, which uses a low-power RC circuit to monitor voltages between 3.0V and 5.5V. In this mode, the voltage detection threshold is adjustable and can be set between 1.4V and 5.5V. This low-power voltage detection mode can be used to monitor low-voltage applications, such as 3.3V or 5V systems, without the need for a significant energy draw.

The BD5234G-TR supervisor IC also features an optional power-off reset (POR) function, which gives the system the ability to detect and reset itself in the event of a system crash. The POR function is triggered when the voltage is detected to have dropped below a specific threshold, at which point the IC will reset the system and allow it to reboot. This can be used to ensure that the system can recover from a crash without user intervention. It can also be used to quickly reboot a system without manually powering off the system.

Conclusion

The BD5234G-TR supervisor IC is a versatile and reliable IC designed for system health monitoring and offer many features in a single package. It is suitable for both battery-powered and low-voltage systems, as well as automotive applications. It utilizes a RC circuit for voltage detection, and offers an adjustable power-off reset function to allow for quick system reboot. With its array of features and reliability, the BD5234G-TR supervisor IC is a great choice for system health monitoring and deriving optimal performance.
