The BD4732G-TR is an active low voltage supervisor integrated circuit (IC). It is an important part of power management in electronic systems, providing reliable circuit supervision and precise protection to the system from potential damage that could be caused by voltage surplus or deficiency. Used mainly in the automotive and communication systems, this supervisor IC can save development time, increase system stability, and ultimately enhance the user experience.

This product mainly consists of two parts: the Voltage Detector and the Voltage Limiter. The Voltage Detector monitors the power supply voltage, using the on-chip adjustable monitoring voltage, divided from the VCC voltage. When the monitored voltage is below the active-low reset threshold, the reset signal is pulled low and reset the system. The voltage limiter circuit detects the possibility of overvoltage leak, and virtually reduces the power supply voltage when the voltages in the circuits of VCC, SCLK and SSEL etc. become too high. The pair of outputs of VCCO and VLIMO can respectively control the switch circuit and the buck converter. A discontinuous oscillator (DPO) is also included to enable oscillation frequency adjustment.

Application field

The application field of the BD4732G-TR mainly includes power management in automotive systems. This IC is especially designed for engine control units and other embedded systems. It is built for detecting low output voltage and high output voltage, which could cause damage to the system or shut down the system unexpectedly. The BD4732G-TR is also used in communication systems such as Bluetooth, Wi-Fi, and GPS, to ensure a reliable power supply.

Working Principle

The BD4732G-TR working principle mainly consists of two parts. The first part is the voltage detection, which operates as low voltage detection. The product is designed to detect a fall of the power supply voltage below a given value, referred to as the Reset Threshold Voltage. Adjusting the RT pin of the IC can adjust the threshold voltage. When the voltage falls below the threshold, the reset output of the IC will become low, resetting the system. The second part is the voltage limiter, which functions as the overvoltage leak protection by adjusting the voltage output associated with VCCO, SCLK, and SSEL.

When these two parts operate simultaneously, the IC is able to monitor and protect the system reliably. When an overvoltage leak presents, the IC tries to reduce the voltage output by diverting the current away from the circuit, thus preventing short circuits and damage. For example, the IC attempts to reduce the voltage output of VCCO connected to the push-pull switch circuit when an overvoltage leak is detected, which in turn helps protect the system from potential overvoltage damage.

The adjustable oscillator provided by the IC further extends the need of power management. The adjustable oscillator can adjust the oscillation frequency of the reset output, and can be used to specify system needs such as the minimum reset output width and reset delay.

In conclusion, the BD4732G-TR is a valuable IC for power management in automotive and communication systems. With its integrated voltage detector and voltage limiter, it can detect potential low output voltage and high output voltage, ensuring reliable power supply and protection to the system.
