PMIC (Power Management Integrated Circuit) supervisors are used in many industrial applications to maintain the stability of power delivery and keep the various electrical system components within their optimum specifications. The BD5248G-TR supervisor is a power integrated circuit (IC) device made by Renesas Electronics, specifically designed for 3.3V systems that require accurate detection of supply voltage and reset functions for power monitoring.

The main application field for the BD5248G-TR supervisor is in systems that require power monitoring and regulation and require a reset function in case of a power failure. It can be used in embedded systems, microcontrollers, and other applications that require power and reset monitoring functions. Some of the specific applications include computers, mobile phones, other consumer electronics, and electronic test equipment.

The BD5248G-TR is designed to detect tri-state voltage levels in both rising and falling edges with a high accuracy. Its detection accuracy is 0.5% highly accurate and can detect voltages in the range of 0.5V to 5.5V. On package, there are 4 power reset pins, 1 voltage supervisor reset pin, and 2 LED driver pins. The LED drivers provide the capability to debug the power monitoring directly onsite.

The BD5248G-TR is also designed with a built-in reset function, where the reset pin is reset in two stages. The reset pin will remain deasserted as soon as a power failure is detected. This prevents the system from restarting due to a sudden power failure. The power-on reset also works as an emergency reset for the circuit, protecting it from power consumption damage caused by an initial mistake in the programming.

The BD5248G-TR is a very power-efficient device and it consumes very low current consumption at just 0.5A. This makes it ideal for battery-powered applications or systems that are required to remain in a standby state. This feature also makes the IC very reliable in case of sudden power off or power-on conditions, as the IC can easily maintain the power conditions in a very short time.

The working principle of the BD5248G-TR supervisor is fairly self explanatory. The power supply to the device is connected to four power reset pins, which detect the input voltage of the device. If the voltage is above the threshold voltage, then the power reset pin will be reset and the internal protection circuit will activate the reset signal. The reset signal will be sent to the voltage supervisor reset pin, which will then send a reset signal to external circuit devices to maintain the system’s stability.

In addition, the two LED driver pins are connected to the power reset pins and can be used to debug the power monitoring directly onsite. This makes it very easy to diagnose any problems associated with the power reset pins.

Overall, the BD5248G-TR supervisor is a very useful power management device that can be used in a variety of applications and is designed to provide reliable and accurate power monitoring and reset functions. It is an economical solution for many power monitoring and reset functions when compared to other PMIC supervisors. The device is small in size, highly power efficient, and provides a high level of accuracy in detecting power failures and resetting the external circuit devices.
