The VN380SP13TR is a power distribution switch and load driver component from STMicroelectronics. This component, which operates from 4.5V to 15V, is a solution for managing, distributing and controlling power in portable, medium and large multisource applications. This component is designed to be highly energy efficient, providing a regulated output voltage with very low quiescent current.

The VN380SP13TR features an adjustable power switch with a maximum on resistance of 7.5Ohms, a wide operating range from -40°C to 125°C and a logic input threshold of 0.9V. It is available in a small form factor package with very low power consumption and can operate at frequencies up to 1kHz.

The VN380SP13TR is ideal for use in automotive and industrial systems where a stable power supply is required. It is also ideal for battery operated applications, since it has very low quiescent current, which helps to extend battery life. The component is also suitable for powering multiple external devices in distributed power systems, since it is capable of supplying up to 1.5A of continuous current and can switch load currents of up to 3A.

The VN380SP13TR is designed with an internal logic circuit which controls the switching of two independent N-Channel FETs. This internal logic circuit consists of an input voltage comparator and a pulse-width modulated (PWM) output control circuit. The input voltage comparator is designed to turn the FETs on/off as the input voltage changes, allowing the output to go high/low with respect to the input voltage. The PWM output is designed to switch the FETs with a frequency of up to 1kHz for low-noise operation.

The VN380SP13TR can operate in either a synchronous or an asynchronous mode. In the synchronous mode, the switching of the FETs is controlled by the input voltage, while in the asynchronous mode the switching is controlled by the logic control. The asynchronous mode is more suitable when application requires quick response time, while the synchronous mode is used when a steady output voltage is required over a wide range of input voltage.

The VN380SP13TR is also designed with protection features such as over-voltage, over-temperature and over-power protection. The integrated over-voltage protection is designed to protect the system from the input voltage exceeding its rated limit, while the over-temperature protection prevents the device from reaching temperatures that could damage it. The over-power protection is designed to detect when the output current is at its maximum rating, and will turn off the switch in order to prevent further damage.

The VN380SP13TR is an ideal choice for powering medium and large distributed power systems. It is capable of switching currents of up to 3A with very low quiescent current and a wide operating range. It is also designed with protection features such as over-voltage, over-temperature and over-power protection for maximum safety. The integrated logic circuit with PWM output control allows for a wide range of applications, from low-noise operation to quick response time.
