Si8239x Data Sheet 4.0 A ISODrivers with 2.5 V VDDI and Safety Features KEY FEATURES The Si8239x combines two isolated drivers with either an independent input control or a single input into a single package for high power applications. All drivers operate with a Two isolated drivers in one package 2.5 V input VDD and a maximum drive supply voltage of 24 V. Up to 5 kVRMS isolation Up to 1500 VDC peak driver-to-driver The Si8239x isolators are ideal for driving power MOSFETs and IGBTs used in a wide differential voltage variety of switched power and motor control applications. These drivers utilize Silicon Enhanced output UVLO safety Laboratories proprietary silicon isolation technology, supporting up to 5 kVRMS with- Status feedback to controller stand voltage. This technology enables high CMTI (100 kV/s), lower prop delays and Both outputs drive low on UVLO skew, reduced variation with temperature and age and tighter part-to-part matching. EN pin for enhanced safety It also offers some unique features such as an output UVLO fault detection and feed- Extended VDDI: 2.5 V 5.5 V back, and automatic shutdown for both drivers, an EN (active high) pin, a safe delayed PWM and dual driver versions start-up time of 1 ms, fail-safe drivers with default low in case of VDDI power-down, and 4.0 A peak output dead time programmability. The Si8239x family offers longer service life and dramatically High electromagnetic immunity higher reliability compared to opto-coupled gate drivers. Extended start-up time (1ms) for safe Automotive Grade is available for certain part numbers. These products are built using initialization sequence automotive-specific flows at all steps in the manufacturing process to ensure the robust- 30 ns propagation delay ness and low defectivity required for automotive applications.
