EVALSTGAP2SCM

EVALSTGAP2SCM Demonstration board for STGAP2SCM isolated 4 A single gate driver Data brief Description The STGAP2SCM is an isolated single gate driver. The gate driver is characterized by 4 A current capability and rail-to-rail outputs, making the device suitable also for high power inverter applications such as motor drivers in industrial applications equipped with MOSFET/IGBT/SiC power switch. Two different variants are available: one with separated source and sink outputs, the other with single output pin and a dedicated pin for Miller clamp function. The EVALSTGAP2S is suitable for both output configuration variants. The device integrates protection functions: UVLO and thermal shutdown are included to simplify the design of high reliability systems. Dual input pins Features allow choosing the control signal polarity and also implementing HW interlocking protection in order High voltage rail up to 1700 V to avoid cross-conduction in case of controller Driver current capability: malfunction. 4 A source/sink at 25 C The device allows the implementation of negative Separate sink and source for simplified gate gate driving, and the on-board isolated DC-DC driving configuration (STGAP2SM) converters allow working with optimized driving 4 A Miller clamp (STGAP2SCM) voltage for MOSFET/IGBT or SiC. Short propagation delay: 100 ns The EVALSTGAP2S board allows evaluating all the STGAP2SCM features while driving a half- UVLO function bridge power stage with voltage rating up to 1700 Gate driving voltage up to 26 V V in TO-220 or TO-247 package. Negative gate driving The board facilitates the selection and On-board isolated DC-DC converters to supply modification of the values of relevant external gate drivers, fed by VAUX = 5 V components in order to ease driver s performance VDD logic supply local 3.3 V or VAUX evaluation under different applicative conditions and fine pre-tuning of final application 3.3 V, 5 V TTL/CMOS inputs with hysteresis components.
