NCP5181: MOSFET / IGBT Drivers, High Voltage, High and Low Side, Dual Input
The NCP5181 is a High Voltage Power Mosfet Driver providing two outputs for direct drive of a 2 N-channel power Mosfets arranged in a half-bridge (or any other high side + low side configuration).It uses the bootstrap technique to insure a proper drive of the High side power switch. The driver works with 2 independent inputs to accomodate any topology (including half-bridge, asymmetrical half-bridge, active clamp and full bridge).
Features- High Voltage Range: up to 600 V
- dV/dt Immunity 50 V/nsec
- Gate Drive Supply Range from 10 V to 20 V
- High and Low DRV Outputs
- Output Source / Sink Current Capability 1.1 A / 2.4 A
- 3.3 V and 5 V Input Logic Compatible
- Up to Vcc Swing on Input Pins
- Matched Propagation Delays between Both Channels
- Outputs in Phase with the Inputs
- Independent Logic Inputs to Accommodate All Topologies
- Under VCC LockOut (UVLO) for Both Channels
- Pin to Pin Compatible with IR2181(S)
|
Applications- Bridge Inverter for UPS systems
- High Power Energy Management
- Half-bridge Power Converters
- Full-bridge Converters
- Any Complementary Drive Converters (asymmetrical halfbridge, active clamp)
