NCP5181/D
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 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 accommodate 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)
These are Pb−Free Devices
Applications
High Power Energy Management
Half−bridge Power Converters
Any Complementary Drive Converters (asymmetrical half−bridge,
active clamp)
Full−bridge Converters
Bridge Inverters for UPS Systems
