Introduction to X40010V8I-BT1

The X40010V8I-BT1 is part of the X400 series of voltage supervisor and reset ICs manufactured by Ricoh, a global leader in industrial automation, power management, and power ICs. The X40010V8I-BT1 monitors the supply voltage and provides a reset output when an out-of-specification condition occurs. The chip operates in both SMD (surface-mount device) and through-hole packaging designs and provides multiple supervisory functions including low-voltage detection, power-on reset (POR), and voltage monitoring.

Application Field and Working Principle

The X40010V8I-BT1 is mostly used in power systems, digital devices, and battery-powered devices. It provides protection against power outages by resetting the device after the supply voltage drops below the programmed level. The chip can also operate as a voltage monitor for time-critical monitoring applications. The X40010V8I-BT1 provides voltage-selection (VSEL) flexibility, meaning the user can program the chip for different applications.The chip\'s power-on reset (POR) functionality monitors the supply voltage to detect when the power supply has been disconnected or shorted. When the supply voltage falls below the programmed threshold, the reset pin outputs a low pulse that resets the device. The chip\'s phase delay clock allows the reset pin to remain low for a specified amount of time after the supply voltage passes back above the set threshold.The X40010V8I-BT1 can generate a negative-going reset output when the supply voltage drops below the programmed minimum limit. The chip extends the reset pulse until the supply voltage is stable, i.e. it has settled within the specified parameters. This is useful in applications where the output voltage has to remain stable after reset. The chip also provides reset hysteresis to ensure reliable reset operation.The X40010V8I-BT1 is highly reliable and provides ESD (electrostatic discharge) protection to protect against accidental discharge. It also has low supply current, and its minimum power-on reset delay, low VT, and reset timeout all contribute towards making it an efficient, reliable voltage supervisor.

Conclusion

The X40010V8I-BT1 from Ricoh is an effective voltage supervisor and reset IC for a variety of power systems and digital devices. It provides protection against power outages and voltage-selection flexibility, and its reset pulse remains low until the supply voltage becomes stable. Additionally, the chip\'s ESD protection and low supply current ensure reliable operation.
