 VN751S is a power management integrated circuit (PMIC) from STMicroelectronics. It is designed to provide a reliable and efficient solution for power distribution, load driving, and other power management applications. It features low-side MOSFET switches, load drivers, adjustable current limiting, and support for up to four switch devices. Its small size, low power consumption, and high precision make it a great choice for applications that require low power, accurate control, and low-current switching.

The VN751S is based on STMicroelectronics’ STVNS75LS family of power management ICs. It contains four low-side MOSFET switches that can be used to switch between two power sources, like a battery and an AC power supply. The switches are capable of switching currents up to 20A, and support a wide range of voltages. Additionally, the switches can be enabled or disabled with an external logic input.

The VN751S also features four load drivers that can be used to control a range of loads, from small LEDs to large motors. The load drivers can be used to control the current flow through the load, as well as the speed of the load. This makes the VN751S suitable for controlling small, medium, and large loads, such as DC fans, motors, solenoids, and other current-controlled devices.

The VN751S also offers adjustable current limiting to protect the load from overloads. This feature allows the user to set the maximum current that can flow through the load, so that if the current exceeds the limit, the load will be disabled. This ensures that the load will not be damaged due to excessive current.

Overall, the VN751S is a compact, low-power, high-precision power management IC that can be used in a variety of applications. It provides reliable power distribution and load driving capabilities, as well as adjustable current limiting protection. Its small size, low-power consumption, and high precision make it an ideal choice for applications that require low power, accurate control, and low-current switching.
