Introduction

The X5083V8 is a supervisor IC from ON Semiconductor. The IC is designed for a wide range of power supply and reset applications, with multiple voltages, timing and operation configuration options. The X5083V8 features self-programming, no-connect operation and precise monitoring with ultra-low power consumption. The X5083V8 is a reliable, cost-effective solution for critical Power Management and Reset applications in automotive, industrial and many other application domains.

Application Field

The X5083V8 is suitable for applications with several different supply voltage levels and different reset configuration settings. Possible applications range from EPLL and PLL frequency control, graphics chips reset and clock synchronization, to sensor activation, RTCs and WD settings. The IC can be easily configured to function as either an adjustable voltage monitor, a simple reset supervisor or a watchdog supervisor, for various system power-up, sequencing and reset management functions.

The X5083V8 has several built-in features which make it suitable for mission-critical and safety-related applications. The IC features fault protection circuitry that monitors for open circuit or short circuit situations, and prevents excessive temperature or current from damaging the system. Additionally, the X5083V8 can be readily configured to enable several power-saving strategies such as low power sleep modes or "Run-Time" mode operation for further reduction of current consumption.

Working Principle

The major functional blocks of the X5083V8 can be seen in the simplified application diagram below. The IC consists of all the necessary components needed to autonomously monitor, reset and control system voltages.

The voltage monitor is the core of the X5083V8 and provides comparison of the system voltage against a user-configurable threshold value. The status of the monitor output can be used as an input for reset, alert, or to initiate power-saving sleep modes.

The reset circuit is programmable with user-selected timeout combinations and offers "reset out" and "latched reset out" signals for system power sequencing and control. The reset out output can be configured in software to funktion as an additional voltage monitor, or an adjustable voltage monitor.

The watchdog timer circuit on the X5083V8 is also programmable and offers time-out sequences for today\'s safety-critical applications. The WD can also be used as a backup for the reset circuit, monitoring a “working” condition of the system to ensure normal operation.

Finally, the X5083V8 includes on-chip circuitry to protect against short circuit and open circuit conditions, as well as providing ESD protection to the power supply voltage pins.

Conclusion

The X5083V8 is an integrated Power Management and Reset IC suitable for a variety of mission-critical and safety-related applications. The IC comprises multiple monitoring, reset and power-saving features as well as fault protection circuitry. It offers a reliable, cost-effective solution for system Power Management and Reset applications with adjustable voltage thresholds and multiple timeout configurations.
