Power management integrated circuits (PMICs) are highly versatile components used to enable and coordinate the operation of a device’s various parts. PMICs allow various power supply functions to be optimized for device performance. Among PMICs, supervisors are a type of circuit block designed to protect an electronic device from power-related issues. This article focuses on the S-80922CLMC-G6ST2U supervisor circuit and its application field, as well as its working principle, in order to illustrate how this supervisor IC provides power supply protection for electronic devices.

The S-80922CLMC-G6ST2U supervisor is a simple supervisor IC designed to provide voltage and current protection for devices that use 3.3V to 6V supply voltage. It includes an internal voltage regulator, an adjustable-precision voltage monitor, an adjustable-delay reset output circuit, and an adjustable-delay power-off delay. This IC is suitable for applications such as handheld computing devices, digital cameras, portable consumer electronics and telecommunication devices.

When the supply voltage falls below the trip point, the S-80922CLMC-G6ST2U IC will start a power supply reset (PSR) process, resetting the power supply in order to ensure protection for the system. The IC also provides a RESET output to the system to notify it of the condition. The RESET output can have a programmable delay time, keeping the output low for the fixed period of time before being released. This delay time can be adjusted to meet the specific requirements of the system.

In addition, the S-80922CLMC-G6ST2U IC features an adjustable power-off delay. This delay allows the system to control the timing of the power-off process, so that the system can finish its tasks before the power is shut off. This is important for mission-critical applications. It also helps to improve the system reliability, since if power is cut off too quickly, sensitive data may be lost.

The S-80922CLMC-G6ST2U IC is designed to provide safe, reliable power management for handheld computing devices and other portable consumer electronics. Its reset output, combined with the adjustable delay timer and power-off delay features, can prevent potential damage caused by power-related issues. Furthermore, its precision voltage monitoring also provides excellent system stability. This makes the S-80922CLMC-G6ST2U an ideal choice for ensuring the safety and performance of electronic devices.
