SI8233AB-C-IS1R

The SI8233AB-C-IS1R is a highly versatile dual-channel isolated gate driver, offering exceptional isolation capabilities with up to 5 VRMS input-to-output isolation and robust driver-to-driver differential voltage protection. It comes in various configurations, including HS/LS and dual driver versions, supporting high switching frequencies of up to 8 MHz. With output current options to suit different power device requirements, this gate driver excels in applications requiring high electromagnetic immunity and minimal propagation delay. It can be controlled using independent HS and LS inputs or PWM inputs, with advanced protection features such as overlap protection and programmable dead time. AEC-Q100 qualification ensures its reliability, and its wide operating range from -40°C to +125°C allows it to perform under extreme conditions. Available in RoHS-compliant packages, the SI8233AB-C-IS1R is a compact and reliable solution for driving power devices while maintaining safety and precision.

The Si823x isolated driver family combines two independent, isolated drivers into a single package. The Si8230/1/3/4 are high-side/low-side drivers, and the Si8232/5/6/7/8 are dual drivers. Versions with peak output currents of 0.5 A (Si8230/1/2/7) and 4.0 A (Si8233/4/5/6/8) are available. All drivers operate with a maximum supply voltage of 24 V.

The Si823x drivers utilize Silicon Labs' proprietary silicon isolation technology, which provides up to 5 kVRMS withstand voltage per UL1577 and fast 60 ns propagation times. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis are available in individual control input (Si8230/2/3/5/6/7/8) or PWM input (Si8231/4) configurations. High integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the Si823x family ideal for a wide range of isolated MOSFET/IGBT gate drive applications.
