SiLM8245 Datasheet | Sillumin

DESCRIPTION The Si LM824x isolated driver family is an isolated dual channel gate driver with different configurations. The Si LM8243/4 are configured as high-side/low-side drivers, while the Si LM8245 are configured as dual drivers. The peak source output current is 4.0A and the peak sink output current is 6.0A. Programmable dead time (DT) feature is available in Si LM8243/4. Pulling high the DIS pin shuts down both outputs simultaneously, and allows for normal operation when the DIS pin is open or pulled low. As a fail-safe measure, primary-side logic failures force both outputs low. The VDDA and VDDB supply voltage are up to 33 V. A wide input VDDI range from 3 V to 18 V makes the driver suitable for interfacing with both analog and digital controllers. All the supply voltage pins have under voltage lock-out (UVLO) protection. The Si LM824x has 5.0k VRMS isolation in SOP16W package and 3.0k VRMS isolation in SOP16 package per UL1577. High CMTI, low propagation delay, small size and flexible configuration make the Si LM824x family is suitable for a wide range of isolated MOSFET/IGBT and Si C or Ga N FET gate drive applications.
