onsemi NCV51561 Isolated Dual Channel Gate Driver

onsemi NCV51561 Isolated Dual-Channel Gate Driver features a 4.5A source and 9A sink peak current with short and matched propagation delays. The NCV51561 is intended for fast switching to drive power MOSFETs and SiC MOSFET power switches.

The onsemi NCV51561 Isolated Dual-Channel Gate Driver has a working voltage of up to 1500VDC provided by two 5kVRMS galvanically isolated gate driver channels. These channels allow many configurations of two low-side, two high-side switches, or a half-bridge driver with programmable dead time.

The NCV51561 delivers other important protection functions such as independent undervoltage lockout for both gate drivers and a dead time adjustment function.
