The LX6431ACLP integrated circuit from LSI is an integrated low power 10V precision voltage reference with an adjustable current limit. It is a high accuracy reference voltage source suitable for use in various power management applications such as voltage regulation, over-temperature protection, and current monitoring. The LX6431ACLP is designed to meet automotive requirements and is qualified according to the AEC-Q100 standard.

The LX6431ACLP provides a programmable 10V precision reference voltage with a low drift of 60ppm/C. It also provides an adjustable low power current limit of up to 2mA with a 0.1V accuracy. In addition, the LX6431ACLP offers programmable output voltage and current limit for applications such as temperature sensors, voltage regulators and load switches. The device is available in the WLP version for automotive applications.

The working principle of the LX6431ACLP is based on the principle of electrostatic field sensing. A p-n junction diode is used to sense the voltage across a series of plates that demonstrate a strong electrostatic field. This construction allows for a very reliable, low drift reference voltage. The plates are patterned on the silicon die and are interconnected with a poly-silicon layer. The voltage across the plates is then compared to a reference voltage, and the output current is adjusted accordingly to maintain the desired voltage.

The LX6431ACLP is widely used in automotive power management applications due to its small size, low power consumption, and high accuracy performance. It is also used in medical, industrial and consumer applications. Typical applications include voltage regulation, over-temperature protection, and current monitoring.
