onsemi NCV57080 Isolated High-Current Gate Drivers
onsemi NCV57080 Isolated High-Current Gate Drivers are single-channel IGBT gate drivers with 3.75kVrms internal galvanic isolation, designed for high system efficiency and reliability. These gate drivers offer options such as Active Miller Clamp (NCV57080A), negative power supply (NCV57080B), and separate high and low (OUTH and OUTL) driver outputs (NCV57080C). NCV57080 Gate Drivers accommodate a wide range of input bias voltages and signal levels from 3.3V to 20V. Typical applications include onboard chargers (OBCs), positive temperature coefficient (PTC) heaters, e-compressors, and automotive power supplies.
Features
- ±8A high peak output current
- Low clamp voltage drop eliminates the need for a negative power supply to prevent spurious gate turn-on (NCV57080A)
- Short propagation delays with accurate matching
- IGBT gate clamping during short circuit
- IGBT gate active pull-down
- Tight UVLO thresholds for bias flexibility
- Wide bias voltage range including negative VEE2 (NCV57080B)
- 3.3V, 5V, and 15V logic input
- 3.75kVrms galvanic isolation
- High transient immunity
- High electromagnetic immunity
- Lead-free, halogen-free/BFR-free, and RoHS compliant
- AEC-Q100 qualified and PPAP capable
Applications
- OBCs
- PTC heaters
- e-compressors
- Automotive power supplies
