Description
NCV51513 is 130 V half bridge driver with high drive current
capabilities and options for DC−DC power supplies and inverters.
NCV51513 offers best in class propagation delay, low quiescent
current and low switching current at high frequencies of operation.
This device is tailored for highly efficient power supplies operating
at high frequencies. NCV51513 is offered in two versions
for propagation delays. With filter version, it has a typical 50 ns
propagation delay, while without filter version it has a typical
propagation delay of 20 ns. Internal 80 ns dead time (xB version) and
interlock function protect the output MOSFETs against cross
conduction events. Enable functionality provides additional system
flexibility and helps reducing power consumption.
