NFAL3512L5B

NFAL3512L5B is a smart power module providing a fully−featured, high−performance inverter output stage for AC induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built−in IGBTs to minimize EMI and losses, while also providing multiple on−module protection features: under−voltage lockouts, over−current shutdown, temperature sensing, and fault reporting. The built−in, high−speed HVIC requires only a single supply voltage and translates the incoming logic−level gate inputs to high−voltage, high−current drive signals to properly drive the module’s internal IGBTs. Separate negative IGBT terminals are available for each phase to support the widest variety of control algorithms.

• 1200V – 35A 3−phase IGBT inverter, including control ICs for gate drive and protections
• Low loss, short circuit-rated IGBTs
• Very low thermal resistance using Al2O3 DBC substrate
• Built−in bootstrap diodes/resistors
• Separate open-emitter pins from low-side IGBTs for three−phase current sensing
• Adjustable over−current protection via integrated sense−IGBTs
• Isolation rating of 2500Vrms/1min
