NCP5181
High Voltage High and Low
Side Driver
The NCP5181 is a High Voltage Power MOSFET Driver providing
two outputs for direct drive of 2 Nâchannel power MOSFETs arranged
in a halfâbridge (or any other highâside + lowâside) configuration.
It uses the bootstrap technique to insure a proper drive of the
Highâside power switch. The driver works with 2 independent inputs
to accommodate any topology (including halfâbridge, asymmetrical
halfâbridge, active clamp and fullâbridgeâ¦).
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 1.4 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
⢠Pin to Pin Compatible with IR2181(S)
⢠These are PbâFree Devices
Applications
⢠High Power Energy Management
⢠Halfâbridge Power Converters
⢠Any Complementary Drive Converters (asymmetrical halfâbridge,
active clamp)
⢠Fullâbridge Converters
⢠Bridge Inverters for UPS Systems
