5 kVrms 4.5-A/9-A Isolated
Dual Channel Gate Driver
SOIC−16 WB
CASE 751G−03
NCV51561
The NCV51561 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 NCV51561 offers short and matched
propagation delays.

Two independent and 5 kV internal galvanic isolation from input
rms
to each output and internal functional isolation between the two output
drivers allows a working voltage of up to 1500 V . This driver can be
DC

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 NCV51561 offers other important protection functions such as
independent under−voltage lockout for both gate drivers and a Dead
Time adjustment function.
