Description

NCP51513 is 130 V half bridge driver with high drive current

capabilities and options for DC−DC power supplies and inverters.

NCP51513 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. NCP51513 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 and interlock

function protect the output MOSFETs against cross conduction events.

Enable functionality provides additional system flexibility and helps

reducing power consumption.
