Si827x Data Sheet 4 Amp ISOdriver with High Transient (dV/dt) Immunity KEY FEATURES The Si827x isolators are ideal for driving power switches used in a wide variety of power supply, inverter, and motor control applications. The Si827x isolated gate drivers utilize Single, dual, or high-side/low-side drivers Silicon Laboratories proprietary silicon isolation technology, supporting up to 2.5 Single PWM or dual digital inputs kVRMS withstand voltage per UL1577 and VDE0884. This technology enables industry High dV/dt immunity: leading common-mode transient immunity (CMTI), tight timing specifications, reduced 200 kV/s CMTI variation with temperature and age, better part-to-part matching, and extremely high reli- 400 kV/s Latch-up ability. It also offers unique features such as separate pull-up/down outputs, driver shut- Separate pull-up/down outputs for slew down on UVLO fault, and precise dead time programmability. The Si827x series offers rate control longer service life and dramatically higher reliability compared to opto-coupled gate driv- Wide supply range: ers. Input supply: 2.55.5 V The Si827x drivers utilize Silicon Labs proprietary silicon isolation technology, which Driver supply: 4.230 V provides up to 2.5 kVRMS withstand voltage per UL1577 and fast 60 ns propagation Very low jitter of 200 ps p-p times. Driver outputs can be grounded to the same or separate grounds or connected to 60 ns propagation delay (max) a positive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis Dedicated enable pin are available in individual control input (Si8271/2/3/5) or PWM input (Si8274) configura- Silicon Labs high performance isolation tions.
