NCV51561 – 5 kVRMS Isolated Dual Channel 4.5/9 A Automotive Gate Driver

Front and back side of the onsemi's NCV51561 automotive gate driver

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 kVRMS (UL1577 rating) galvanically isolated gate driver channels 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 enable pin shutdown both outputs simultaneously when is set low. The NCV51561 offers other important protection functions such as independent under-voltage lockout for both gate drivers and enable function.
