PMIC (Power Management Integrated Circuits) are used to manage energy in today’s high tech gadgets. Supervisors are one of the most essential building blocks of the power system in these devices. XC6118N33AGR-G is one of the supervisors that has various applications and works in different ways.

Overview

XC6118N33AGR-G is a single-channel supervisory circuit with a watchdog timer and a reset output. It provides safety against overvoltage, undervoltage, or excessive current. It is also capable of detecting overheating in devices. It monitors the device during power-up and power-down, and reset to prevent system malfunctions. This circuit is an ideal choice for applications that use high efficiency regulators, battery operated devices, and portable electronics.

Features

• Detects overvoltage, undervoltage, and excessive current
• Wide operating voltage range (2.5V to 5.5V)
• Small package size (3.3mmx3.3mm)
• Low operating current (2 A)
• High accuracy detection (±1.6% overvoltage and undervoltage, +/-2% current)
• Robustness to noise
• Reset output logic

Application

XC6118N33AGR-G is widely used in consumer electronics such as digital cameras, cell phones, portable audio players and other embedded systems. It can also be used for medical, automotive and industrial applications that require high accuracy voltage supervision.

Working Principle

XC6118N33AGR-G detects excessive current, overvoltage, and undervoltage events and generates a reset signal. It uses low current and a tight detection voltage accuracy to ensure a power safe design. The watchdog timer of the circuit is programmable and generates an alert when it detects an abnormal condition.

The circuit uses an internal comparator and an input voltage divider to detect over/under voltage conditions. It also has an internal current amplifier to detect excessive current. The detected signals are compared to internal reference voltages, and if they exceed the specified limit, a reset signal will be triggered. This ensures the circuit’s correct operation even if there is a fault in the system.

Conclusion

XC6118N33AGR-G is a single-channel supervisory circuit with a watchdog timer and a reset output. It is ideal for applications that require high accuracy voltage supervision. It can be used for a wide range of applications such as digital cameras, cell phones, and portable audio players. It is also suitable for medical, automotive and industrial applications.
