The LT1764EFE-1.5#TRPBF is a voltage regulator and current limiter best-suited for a variety of applications. It is a monolithic linear device consisting of an N-channel MOSFET as a pass device and an adjustable voltage reference to limit the output voltage. The device is designed to save power and improve efficiency in a wide range of devices from mobile phones to industrial equipment.

Application Fields

The LT1764EFE-1.5#TRPBF is particularly well-suited for use in mobile phones and industrial applications. It replaces the linear regulator and diode shunt regulator used for such applications as these components require additional external components, whereas the LT1764EFE-1.5#TRPBF can be used to directly regulate and limit the output current without the need of any external capacitors. The device also ensures output voltage accuracy over varying loads and temperature ranges without the need to exceed the maximum power dissipation of the device.

The LT1764EFE-1.5#TRPBF is also extensively used in systems with battery-powered sensors and actuators. These systems require a high transmission efficiency and a constant output in order to ensure reliable operation. The device is an ideal solution due to its low quiescent current and its ability to limit the output current to the value letting the slightly higher set-point of the current output setting. The device also improves battery life as lower C-rates are attained.

Working Principle

The LT1764EFE-1.5#TRPBF consists of an internal N-channel MOSFET as the pass device and an adjustable voltage reference to limit output voltage. The device operates as a linear regulator in the constant voltage mode by comparing the reference voltage from the internal reference pin to the output voltage through the regulation and flow control pins. The device turns the N-channel MOSFET on and off in order to regulate the output voltage. When the device is turned on, the voltage at the reference pin controls the conduction as a function of current through the pass transistor.

The LT1764EFE-1.5#TRPBF also operates as a current limiter. When the output current reaches the current limiter setting, the device turns off the MOSFET pass device and stops regulating its output voltage. This ensures that if an overload situation happens, the device will protect the circuitry from any damage. The device also features an enable/disable pin that allows to quickly enable and disable the regulation and current limit function.

Finally, the LT1764EFE-1.5#TRPBF features a number of protection features such as reverse current protection, thermal shutdown, and short circuit protection. These features work in addition to the current limiter and enable the device to be used for any application with a high degree of reliability.
