The S-80842CLY-B2-U is a member of SEIKO Devices Corporation’s family of PMIC Supervisors. The device provides one central supervisor solution or circuit monitoring system for industrial, consumer, and automotive applications. The device features multiple optional features, including push-pull output, active-low reset output, programmable reset generation delay time, 2 active-low reset output, selectable reset time-out, input logic selectable, and a maximum interval of 32ms between two reset pulses.

The S-80842CLY-B2-U is widely used for providing an extended reset circuit for equipment that requires an adjustable reset time-out. It is also an ideal solution for microprocessor-based applications that need reliable system reset for overvoltage protection, thermal protection, or circuit monitoring. The S-80842CLY-B2-U includes an active low reset output, enabling it to be used for closed loop temperature control. The device also offers two active-low inputs, allowing it to be used for circuits that require both assert and de-assert function.

The S-80842CLY-B2-U can detect a single or multiple power supply conditions, such as high or low. The device features an adjustable reset generation delay time and adjustable reset time-out. This is essential for applications that need to monitor the voltage integrity of a wide range of power supply conditions. The device supports input logic selection and the appropriate reset generation delay time can be programmed by the user.

The working principle of the S-80842CLY-B2-U is as follows: The device monitors the input voltage and if it remains above the set threshold for more than the set reset time-out, it generates a reset pulse which is applied to the reset output. If the voltage returns to normal before the set time-out, the reset pulse is cancelled and the device resumes normal operation. The device monitors the voltage and reports voltage abnormalities via the reset output.

The S-80842CLY-B2-U offers a variety of selectable reset time-outs, including 0S, 10S, 20S, and 32S max. This enables it to be used in a variety of applications that require a wide range of power supply conditions. The device is designed to be a highly reliable and cost-effective solution for system reset, overvoltage protection, thermal protection, and circuit monitoring.

To conclude, the S-80842CLY-B2-U is a PMIC supervisor designed for industrial, consumer, and automotive applications. It provides an adjustable reset time-out, making it ideal for microprocessor-based systems. It can detect a single or multiple power supply conditions, and features an adjustable reset generation delay time and active-low reset output for closed loop temperature control. Additionally, the device offers two active-low inputs for circuits requiring both assert and de-assert functions. With its wide range of selectable reset time-outs, the device is an excellent, cost-effective solution for system reset, overvoltage protection, thermal protection, and circuit monitoring.
