LM4040D50ILPR Application Field and Working Principle

PMIC or Power Management Integrated Circuits are integrated circuits used for the efficient management of power, which generally includes power conversion, power monitoring and control, and the protection of systems from power disturbances. The LM4040D50ILPR is a type of Voltage Reference PMIC.Voltage Reference PMICs provide a fixed reference voltage, acting as a voltage source from which other outputs can be measured. The LM4040D50ILPR is a 2.50V precision voltage reference with a temperature stability of ±0.8 mV over the operating temperature range. Its low output noise and high-accuracy make it suitable for a wide range of applications, including feedback stabilisers, analog-to-digital converters, and monitoring battery voltage.The LM4040D50ILPR is based on a proprietary tailored diffused zener reference. This design is highly stable and reliable, making it ideal for harsh environments, while its low power consumption delivers excellent power savings. The device is also covered by a 20-year warranty and is qualified to AEC-Q100 Grade 1, making it an excellent choice for demanding automotive applications.This voltage reference is available in the extremely small SC70-6 and SOT-23-5 packages, making it suitable for a variety of space-constrained applications. It also operates over a wide input voltage range of 2.7 to 6.5V and can deliver up to 10mA of current.The LM4040D50ILPR is also incredibly easy to use, featuring an open-drain enable pin that can be used to enable or disable the device. In enable mode, the output voltage is held constant, while in disable mode, the output is actively pulled down and the device is turned off.To summarize, the LM4040D50ILPR is an excellent voltage reference specifically designed for automotive applications. Small form factor, good temperature stability, and low output noise make it an ideal choice for system designers seeking a reliable and easy-to-use solution.
