XC6124 series is a line of supervisory circuits by Svsan. It provides precision voltage and time monitoring of the supply voltage and external supply voltage for reset. The devices are available in 5-pin SOT-25 package, with precise detection voltage ranges and precise reset timing. Supervisory circuits provide system designers with improved accuracy and reliability, while occupying less board space.

The XC6124A733MR-G is a 5-pin SOT-25 supervisory circuit that is typically used to monitor 3.3 V, 2.5 V and 1.8 V system power supply voltages in computer systems, communications equipment, industrial control systems and other electronic equipment. It is an ultra-low power CMOS device that is both accurate and reliable. It is designed for single supply voltage applications.

Applications for XC6124A733MR-G:

• Monitoring system power supply in computers, communications equipment, industrial control systems and other electronic equipment.
• Voltage debounce for system power sequence reset.
• Providing a precise reset pulse for microprocessor systems.
• Providing system reset in low power applications.

The XC6124A733MR-G operates with a single supply voltage and provides a reset output at a precise threshold voltage. It also provides an externally adjustable reset threshold voltage and a low offset voltage between the reset threshold and release threshold. The reset output remains active if the power supply voltage is below the reset threshold. To prevent false reset due to power supply droops, the reset must be triggered again when the voltage goes below the reset threshold. To prevent false reset due to noise, the reset must be held low for a specific amount of time.

The XC6124A733MR-G includes a low power consumption internal oscillator with selectable time constants. It also provides an output reset active time of 2.64 ms min, an active time of 33.1 ms max and an active time of 153 ms max. The reset output is active for a pre-set time after the power supply voltage is detected to be below the reset threshold.

The XC6124A733MR-G operates from a single +3.3V power supply and features low power consumption (5uA max supply current). It is available in the SOT-25 package and the SOT-23 package.

In conclusion, the XC6124A733MR-G is a 5-pin SOT-25 supervisory circuit that is typically used to monitor 3.3 V, 2.5 V, and 1.8 V system power supply voltages in computer systems, communications equipment, industrial control systems, and other electronic equipment. It includes an internally adjustable reset threshold voltage, a low-offset voltage between the reset threshold and release threshold, a low power consumption internal oscillator with selectable time constants, and a reset output active time. It is an ultra-low power CMOS device that is both accurate and reliable and is designed for single supply voltage applications.
