Isolators - Gate Drivers

SI8752AB-AS isolators are Gate Drivers designed for advanced applications such as lighting, motor control, and automotive applications. This device combines high-speed isolation technology and automotive grade HDL block using a single chip that helps eliminate EMI/RFI noise, as well as providing reliable electrical isolation at low cost.

The SI8752AB-AS has a power MOSFET driver that enables it to work with higher voltage applications. It is capable of direct drive for solenoid coils and provides both overvoltage and undervoltage protection. The integrated MOSFET transistor is suited for high peak currents, fast turn-off, and low ON resistance providing maximum energy efficiency.

The SI8752AB-AS offers an industry leading fast Auto Shutdown (FAD) solution for applications that require an immediate tri-state of the MOSFET. The FAD function helps reduce power consumption in floating conditions, implementing a new level of efficiency. It is also designed to reduce device heating during operation, thus ensuring an extended durability of the device.

Aside from its power MOSFET driver, the SI8752AB-AS is also capable of providing an optical isolator gate driver IC for LED applications. The integrated optical isolator gate driver IC allows for the fast isolation of internal circuitry, while also providing improved noise immunity and power efficiency.

The SI8752AB-AS has four separate digital inputs and one analog input to meet the needs of a wide range of applications. The digital inputs are capable of switching on/off the MOSFET driver circuit and controlling the LED driver IC. The digital pins can also be used to set the state of the MOSFET driver based on user input. The onboard analog input can be used to smoothly transition the duty cycle of the MOSFET driver circuit for applications that require PWM control.

The SI8752AB-AS is ideal for use in lighting, motor control, and automotive applications that require advanced gate driving capabilities with high-speed isolation. This device combines the benefits of a MOSFET driver and optical isolator with ease, providing an excellent solution for noise-immune, power-efficient, and reliable gate drive applications.
