Power management integrated circuit (PMIC) devices are electronic components that manage the power supplied to electrical circuits. Specifically, supervisory PMIC devices provide a signaling mechanism for electronic devices, alerting them of events occurring within a system. The S-80144BNPF-JG5TFG is one such PMIC - Supervisor device. This paper will discuss the application field and working principles of the S-80144BNPF-JG5TFG and outline the key features that make it an ideal solution for power regulation and clock synchronization.

Application Field

The S-80144BNPF-JG5TFG is a supervisor device specifically designed to regulate discrete power rails statuses in computing and communications systems. It\'s primary application field is in notebook and server systems. Other applications include traffic control, medical instrumentation, and industrial automation. The S-80144BNPF-JG5TFG is well-suited for power-sensitive, highly integrated systems where fast start-up times are essential and accurate power control is essential.

Working Principles

The S-80144BNPF-JG5TFG is a highly integrated power management supervisor device, consisting of an on-board voltage reference, monitoring comparator, reset output, status outputs and open-drain interrupt output. It manages power rails, detects power rail failures, and synchronizes clock signals.

The on-board voltage reference and monitoring comparator are used to monitor the power rail voltage and set the voltage threshold value. Once the power rail voltage falls below the threshold value, the monitoring comparator triggers a reset output and the S-80144BNPF-JG5TFG will initiate a power-down sequence.

The S-80144BNPF-JG5TFG is designed for minimization of false alarms and timing criticality. The reset output is adjustable from 1 millisecond to 5 seconds to ensure an accurate and timely reset. A status output is also included to alert the user of the device’s status. An open-drain interrupt output is provided for low-level power monitoring.

Key Features

The S-80144BNPF-JG5TFG is a low power supervisor device with many features that make it ideal for power regulation and clock synchronization. These features include:

• Low operating current – as low as 0.21µA
• High accuracy voltage reference – 0.7%
• Fast response time – as low as 15µs
• Programmable reset threshold – 0.8V to 6.4V
• Programmable reset delay – 1ms to 5sec
• Open-drain interrupt output – low level power detection

The S-80144BNPF-JG5TFG is designed for easy integration for existing system designs. It supports a variety of input and output signal standards, including SEL and reset types, and is provided in a small, 8 pin package.

Conclusion

The S-80144BNPF-JG5TFG is an ideal solution for power regulation and clock synchronization in notebook and server systems, as well as other application fields such as traffic control and industrial automation. The device’s integrated voltage reference and monitoring comparator provide accuracy and stability, while the adjustable reset threshold and delay minimize false alarms and timing criticality. With its wide range of input and output signal standards, the S-80144BNPF-JG5TFG provides an easy integration into existing system designs, making it the ideal choice for power and clock synchronization.
