BD4734G-TR Application Field and Working Principle

PMIC (Power Management Integrated Circuit) supervisors are designed to monitor the supply voltage to detect any unstable feedback. Among these supervisors is the BD4734G-TR, an IC commonly used in consumer electronics, automotive and some industrial applications. Its main applications include power-on reset and power-off reset functions.

The overall working principle of the BD4734G-TR supervisor is divided into two phases. The first phase is the power-on reset part where it receives the input voltage and supplies a reset signal to the system when there is any instability generated in the supply voltage. The second phase of operation is the power-off reset part where the supervisor detects the decrease in the supply voltage and sends out a reset signal to the system.

The power-on reset part of the BD4734G-TR supervisor can easily be integrated into any power-supply circuits and will prevent system reset due to excessive ripple noise or microcontroller malfunctions. It monitors the input voltage and sends a reset signal to the system when the voltage falls below the preset threshold. The reset signal has a specified timeout period which can be used to reset the system in cases of excessive noise. When the power-on reset is completed, the supervisor supplies a “Power-OK” signal to the system. This signal serves as an indication of stable output.

In the power-off reset stage, the supervisor monitors the input voltage for its decrease. In the case of sudden drop, the supervisor immediately sends a reset signal to the system which then halts the system. The BD4734G-TR supervisor has an adjustable time period that can be set to issue a reset signal constantly after the initial drop; this feature is used to reset the system constantly in the case of power loss.

In order to make the BD4734G-TR supervisor suitable for different applications, a few different voltage options are available. The supervisor can be used with a wide range of input voltage options varying from 1.1V to 5.5V. It has a very low standby power consumption of 1µA and a very low output operating voltage of 0.3V. The operating temperature range is from -40°C to 85°C.

The BD4734G-TR supervisor is an ideal choice for applications requiring a reliable power monitoring as it is a highly reliable and low cost IC. It has a low power consumption and adjustable thresholds and signals for use in different systems. The wide voltage range and wide operating temperature range make it suitable for various applications.
