Twin-Channel Gate-Driver For Quick Switching Energy Functions

Onsemi has launched NCV51561 Remoted Twin-Channel Gate-Driver for a wide range of energy electronics purposes like chargers and inverters.

onsemi NCV51561 Remoted Twin-Channel Gate Driver encompasses a 4.5A supply and 9A sink peak present with brief and matched propagation delays. The NCV51561 is meant for quick switching to drive energy MOSFETs and SiC MOSFET energy switches.

The onsemi NCV51561 Remoted Twin-Channel Gate Driver has a working voltage of as much as 1500VDC supplied by two 5kVRMS galvanically remoted gate driver channels. These channels enable many configurations of two low-side, two high-side switches, or a half-bridge driver with programmable useless time. Two unbiased and 5 kVRMS (UL1577 score) galvanically remoted gate driver channels can be utilized in any potential configurations of two low aspect, two high-side switches or a half-bridge driver with programmable useless time.

The NCV51561 delivers different essential safety capabilities reminiscent of unbiased undervoltage lockout for each gate drivers and a useless time adjustment perform.
