Overview

This reference design provides an integrated high and low side isolated primary gate driver solution for an automotive battery charging system incorporating two push-pull SN6505B transformer drivers and the isolated dual-channel gate driver UCC21521C.

Features
  • Split rail +15-V / -4-V output
  • Negative 4-V output for fast FET turn off
  • Small 1.500" x 1.750" board dimensions
  • High FET drive current up to 120 mA allows for lower switching losses
