Introduction

X4163V8I-2.7 is one of the power management integrated circuits (PMIC) from Maxim Integrated. It is a dual reset supervisor that can be used in a wide range of applications, from microcontrollers to large system on chips (SoC). The device offers a 1ms reset, auto-clearing of the reset latch, and is RoHS compliant. This article will discuss the application fields and working principle of the X4163V8I-2.7.

Application Fields

The X4163V8I-2.7 is primarily designed as a watchdog timer supervisor and a general purpose reset supervisor. It can be used in different application fields.For high-end microcontroller applications, the X4163V8I-2.7 provides an accurate 1 ms reset pulse that can be used to safely reset the device and ensure a fast start-up. It can be used to guard against and reset system instability issues due to software malfunctions. The device also contains a temperature monitoring function, which is important in safety-critical applications.In industrial automation and embedded applications, the X4163V8I-2.7 can be used to safely and reliably monitor a critical system. The device can detect and latch system over-temperature events and provide a reliable reset pulse for recovery.The device can also be used in consumer electronic applications. It allows for automatic system resetting to prevent system crashes and to protect against dangerous system interactions.

Working Principle

The working principle of the X4163V8I-2.7 is based on a dual reset supervisor design. The device monitors the power supply inputs and outputs, as well as its temperature, to detect any irregularities or unsafe conditions.When an unsafe condition is detected, the device signals an alarm and its reset line goes low. This will reset the system and prevent any further unsafe conditions. When the condition is resolved, the device will clear the reset latch and return to the normal state.The device also has a watchdog input that can be used to monitor system activity. If the application fails to respond to the watchdog input within a specified period of time, the device will reset the system.In addition, the X4163V8I-2.7 contains both a VCC-dependent automatic reset (AR) and a temperature-dependent automatic reset (TR) for additional safety. It also offers robust input/output interface design.

Conclusion

The X4163V8I-2.7 is a dual reset supervisor that can be used in a wide range of applications, from microcontrollers to large system on chips (SoC). It can be used to guard against and reset system instability issues due to software malfunctions, and to detect and latch system over-temperature events. The device also contains a temperature monitoring function and a watchdog input that can be used to monitor system activity. It offers a 1ms reset, auto-clearing of the reset latch, robust input/output interface design, and is RoHS compliant.
