BD4858G-TR Integrated Circuits (ICs)

PMIC - Supervisors

BD4858G-TR is a recently developed integrated supervising solution specifically designed to detect faults in power supplies. It features a multi-channel open-collector output that can quickly detect low- and high-voltage conditions within a wide operating voltage range from 1.2 to 3.6V. This supervisor is built using a high-performance CMOS technology for improved reliability, accuracy, and cost-efficient operation.

Application Field

The BD4858G-TR supervisor is a flexible solution for modern power supplies and it is suitable for a wide range of applications, including system power supply fault detection, backlight circuit power failure detection, power malfunction detection, power supply failure detection, input voltage monitoring, and output voltage monitoring.

In addition, the BD4858G-TR supervisor can be employed in numerous PC and server systems, storage systems, automotive electronics, medical equipment, 3D printers, cell phone chargers, as well as other applications where a reliable power supply is essential.

Working Principle

The BD4858G-TR supervisor acts as a voltage monitor that can detect faults in power supplies. It is designed with a multi-channel open-collector output that is capable of determining the voltage level of the supplies or loads. When the input voltage exceeds or falls short of the preset voltage level, the output signal goes to its low state.

The BD4858G-TR supervisor comes with an internal hysteresis to enhance its detection accuracy and improve the overall stability of its output logic. It also includes an oversampling circuit to protect against noise interference. Furthermore, the supervisor has adjustable hysteresis for more precise voltage monitoring, as well as a detection delay circuit for delayed power-on.

Conclusion

The BD4858G-TR supervisor is a reliable and cost-effective voltage monitoring solution designed to detect power supply faults in a wide variety of applications. With its multi-channel open-collector outputs, adjustable hysteresis and built-in oversampling circuit, this supervisor simplifies the task of voltage monitoring and provides accurate, stable detection results. Additionally, it is backed by a robust design and reliable CMOS technology to ensure long-term performance and dependability.
