The NCP51561 are isolated dual?channel gate drivers with

4.5?A/9?A source and sink peak current respectively. They are

designed for fast switching to drive power MOSFETs, and SiC

MOSFET power switches. The NCP51561 offers short and matched

propagation delays.

Two independent and 5 kVrms internal galvanic isolation from input

to each output and internal functional isolation between the two output

drivers allows a working voltage of up to 1500 VDC. This driver can be

used in any possible configurations of two low side, two high?side

switches or a half?bridge driver with programmable dead time.

An ENA/DIS pin shutdowns both outputs simultaneously when set

low or high for ENABLE or DISABLE mode respectively.

The NCP51561 offers other important protection functions such as

independent under?voltage lockout for both gate drivers and a Dead

Time adjustment function.
