Introduction

The S-80839CLNB-B6YT2U is an ultra-low power voltage supervisor, belonging to the family of PMIC (Power Management Integrated Circuits). The device integrates two voltage detection circuits and a power-on reset circuit in a single monolithic IC, making it one of the most cost-effective solutions for chip reset and reset recovery, system power-up, and power failure detection.

Application Field

The S-80839CLNB-B6YT2U is typically used for chip reset, system power-up, memory reset, reset recovery, and alarm operation on board systems. It provides a very stable and reliable reset/control operation that is suitable for a wide variety of applications, such as personal computers and peripheral equipment, communication terminals, automotive applications, industrial control systems, and consumer electronics.The device can be used in various industrial applications, including the management of automation systems, safety control of industrial production lines, fail-safe monitoring of static machines and control systems, and remote monitoring of motors. It can also be used as a protective device in medical equipment, office automation, and telecommunications products.

Working Principle

The S-80839CLNB-B6YT2U voltage supervisor is a low-voltage monitoring device that monitors an applied voltage input and provides an output reset signal when the voltage falls below the internally pre-set threshold. It has a power-on reset (POR) feature that detects and recovers from system power-up and power failure scenarios, and two dedicated detection circuits (INA and INB) that can detect an external voltage of up to 6V for enhanced protection. The INA and INB inputs are both connected to ground when the corresponding voltage level is lower than the set threshold voltage. If either of these inputs is above the set threshold, the output is driven to a high level, signaling a logical low at the output. The reset signal lasts as long as the detected voltage remains above the threshold. The S-80839CLNB-B6YT2U also features an adjustable delay timer that determines the maximum time of reset output. The delay time is programmable with an external RC network, providing flexibility in preventing false outputs due to system transients.

Conclusion

The S-80839CLNB-B6YT2U voltage supervisor is an ideal solution for reset and reset recovery, system power-up, and power failure detection, and has wide application in personal computers and peripheral equipment, communication terminals, industrial control systems, consumer electronics, and automotive systems. It provides low power consumption, reliable reset/control output, adjustable delay timer, and a wide detection voltage range of 0.7V to 6V, making it an ideal device for a wide variety of reset and control needs.
