SI8235AD-C-ISR

The SI8235AD-C-ISR is an isolated gate driver that offers up to 5 kVRMS input-to-output isolation, impressive peak output current handling capabilities (0.5 A or 4.0 A), high electromagnetic immunity, low propagation delay, and various control options. It features overlap protection and programmable dead time, making it a reliable choice for power electronics applications. This gate driver is AEC-Q100 qualified, operates over a wide temperature range (-40 to +125°C), and is available in RoHS-compliant packages, including SOIC-16 wide body, SOIC-16 narrow body, and LGA-14. Its exceptional isolation, current-handling capabilities, and protective features make it a compelling choice for high-reliability applications, such as automotive and industrial systems.

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.
