UCC27321DRG4

单9A高速低侧MOSFET驱动器与启用 SINGLE 9-A HIGH SPEED LOW-SIDE MOSFET DRIVER WITH ENABLE

DESCRIPON

The UCC37321/2 family of high-speed drivers deliver 9 A of peak drive current in an industry

standard pinout. These drivers can drive the largest of MOSFETs for systems requiring extreme Miller current due to high dV/dt transitions. This eliminates additional external

circuits and can replace multiple components to reduce space, design complexity and assembly

cost. Two standard logic options are offered, inverting UCC37321 and noninvertingUCC37322.
