It is also used in automotive electronics, industrial control systems, power supplies and other applications that require regulated voltage output.

Working Principle

The LT6654AMPS6-3#TRMPBF is a three-terminal device with two independent references. The reference is comprised of a precision band-gap reference, temperature-compensated voltage reference, series resistor, as well as an impedance buffer for input and output. The precision band-gap reference and temperature-compensated voltage references provide a stable output voltage over a wide temperature range. The series resistor provides current limiting protection and the impedance buffer helps with input and output impedance. This combination of components provides a reliable and accurate output voltage that can be easily adjusted for different application requirements.

When the input voltage changes, the adjustable resistor is used to adjust the output voltage so that it stays within an acceptable range. The output from the adjustable resistor is compared with the reference voltage from the precision band-gap reference and the temperature-compensated voltage reference. If the output voltage is too high, the device will reduce the output voltage. Conversely, if the output voltage is too low, the device will increase the output voltage. This adjustment process is continuous and helps ensure that the output voltage remains within the acceptable range at all times.

Conclusion

The LT6654AMPS6-3#TRMPBF is a PMIC voltage reference device that is used in various applications to regulate the output voltage and provide over-voltage or under-voltage protection. It has a wide operating temperature range from −65°C to +150°C, a wide input voltage range from 1.4V to 11V, and a fast start-up time of 4 µs. It is typically used in battery management, including chargers and conditioning circuits, automotive electronics, industrial control systems, power supplies and other applications.
