Introduction

The XC6124A233MG-G is a low drop-out supervisory, undervoltage monitoring IC, typically used to protect system power and reset microcontrollers or other digital circuits from a low-voltage condition. It comes in a tiny SOT-23 package, making it suitable for use in small handheld equipment.

Application Field

The XC6124A233MG-G is designed for use in a variety of applications, including: - Portable instrumentation- Battery-operated products- Point-of-sale systems- Automotive control systems- Wireless communication systems- Fax machines- PDAs

Working Principle

The XC6124A233MG-G can detect any voltage below the preset threshold and generate an active-low reset signal. The reset signal will be released once the voltage rises above the default threshold. The device also features a built-in delay timer, adjustable via an external resistor, which can be used to slow down the reset signal, giving the system a chance to stabilize. The IC employs a current-source design, enabling high accuracy over a wide temperature range. The high impedance MOSFET input and the low current consumption allows the IC to operate with high precision while consuming only a minimum amount of power. The wide input voltage range (from 1.8V to 6V) gives the IC a lot of flexibility, allowing it to be used in a variety of applications. The XC6124A233MG-G is fully ESD protected, making it suitable for use in harsh, electrically noisy environments. The SO-23 package takes up a minimum amount of space and is EMI/RFI shielded, making it ideal for use in portable equipment.

Conclusion

The XC6124A233MG-G is a low drop-out supervisory, undervoltage monitoring IC, designed for use in a variety of applications, from portable instrumentation to automotive control systems. It is able to detect any voltage below the preset threshold and generate an active-low reset signal, with the option of adding a delay timer via an external resistor. The SO-23 package is EMI/RFI shielded and the IC is ESD protected, making it suitable for use in harsh environments.
