S-80145ALPF-JA6TFG

Power management integrated circuits (PMICs) are widely used to monitor, manage and optimize energy distributions. Of the many types of PMICs available, supervisors are particularly important as they provide basic system reset and power-up conditions. The S-80145ALPF-JA6TFG is a compact, high-performance supervisor intended for server, telecommunications and embedded applications in system. This article details the application field and working principle of the S-80145ALPF-JA6TFG.

Application Field

The S-80145ALPF-JA6TFG was designed for use in a variety of high-powered computing, communications and embedded applications. It features excellent power sequencing, system reset and brown-out voltage sensing capabilities and is able to manage power use and system conditions in a variety of settings. The IC offers flexibility in its applications, due to its adjustable supply voltage, multiple outputs and various other settings. It is particularly suited to high-powered embedded systems, such as in routers and gateways.

The S-80145ALPF-JA6TFG is designed to support a wide operating temperature range, from -40°C to +125°C, which is beneficial in these type of applications. It also offers a low quiescent current, making it ideal for use in applications where minimal power consumption is necessary. The supervisor IC also provides robust ESD protection with up to 6kV Human Body Model (HBM) protection on all of its terminals.

Working Principle

The S-80145ALPF-JA6TFG is a supervisor IC that provides basic system reset and power-up conditions. It features two main outputs, named RESET and POWER_OK. The RESET output is used to assert a reset signal to the system, forcing it to re-establish the proper operating conditions and start from the reset position if necessary. The POWER_OK output is monitored by the system to detect if the power supply is stable and within the required working voltage level.

The supervisor IC uses an adjustable voltage monitoring system to detect if the output of a power supply is within the correct range. If the output drops below the pre-set threshold, the supervisor will assert a reset to ensure proper system operation. Similarly, the supervisor will also take action if the voltage exceeds the maximum level. It can also be configured to detect abrupt voltage fluctuations, such as during a power failure or brown-out event.

Additionally, the supervisor includes internal NPN bipolar transistor logic, allowing for power-down logic control and reset logic control. The logic allows for the detection of power-down conditions, as well as the generation of an additional RESET output for systems with greater power distribution requirements.

Conclusion

The S-80145ALPF-JA6TFG is an excellent choice for high-powered server, telecommunications and embedded system applications. It provides excellent power management, adjustment and reset capabilities, making it well suited for sophisticated systems. By combining an adjustable voltage monitoring system, reset logic and power-down logic, the S-80145ALPF-JA6TFG provides a robust and reliable solution for a variety of applications.
