Introduction

S-80140BLMC-JEZT2U is a high-performance PMIC supervisor from the SPX family, designed for the latest process nodes. It is a two-output, dual-voltage supervisor integrated with comprehensive fault protection and a range of flexible control and reset timing options. It offers power management, voltage regulation, reset generation, and system scaling functions to protect against faults due to power supply, communication interface, and system issues.

Application Fields

The S-80140BLMC-JEZT2U is designed to meet the increasingly complex demands of electronic system designs. It is suitable for use in a wide variety of applications, such as in industrial, automotive, and medical applications. Examples of applications in which the supervisor can be used include:

• Multi-Core Embedded Systems and Artificial Intelligence (AI)
• Servers and Workstations
• Smartphones and Tablets
• Industrial Automation
• Medical Devices
• Internet of Things (IoT)

Working Principle

The S-80140BLMC-JEZT2U can be used to monitor two independent input signals (e.g. power supply rail voltage, system clock, watchdog timer etc.). When either of the input signals deviates from the configured range (e.g. a power rail voltage drops below its normal operating voltage, or a clock frequency is too fast or too slow) then the supervisor will automatically generate a reset or interrupt signal to the system. When the system recovers, the supervisor will automatically reset and continue normal operations.

In addition to monitoring power supply rails, the supervisor can also be used to generate reset signals if the watchdog timer (WTD) has expired. The WTD is normally used to detect system hangs or infinite loops and can be programmed to generate a reset signal after a certain time period.[The S-80140BLMC-JEZT2U also has a dual-voltage core, allowing for voltage scaling for improved power efficiency. This feature is especially useful for AI and server applications, where power efficiency is a key factor.

Conclusion

The S-80140BLMC-JEZT2U is a high-performance PMIC supervisor from the SPX family, designed for the latest node sizes and applications. It offers comprehensive fault protection and a range of flexible control and reset timing options for power management, voltage regulation, reset generation, and system scaling functions. The S-80140BLMC-JEZT2U is suitable for use in a wide variety of applications, such as in industrial, automotive, and medical applications.
