Onsemi NCP5181 | Demoboard 1kW motor control inverter

Description

The NCP5181 is a High Voltage Power MOSFET Driver providingtwo outputs for direct drive of 2 N−channel power MOSFETs arrangedin a half−bridge (or any other high−side + low−side) configuration.It uses the bootstrap technique to insure a proper drive of theHigh−side power switch. The driver works with 2 independent inputsto accommodate any topology (including half−bridge, asymmetricalhalf−bridge, active clamp and full−bridge…).

Features

• 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 1.4 A / 2.2 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

• These are Pb−Free Devices

Typical applications

• Bridge Inverters for UPS Systems
• High Power Energy Management
• Half−bridge Power Converters
• Any Complementary Drive Converters (asymmetrical half−bridge, active clamp)
• Full−bridge Converters
