• LTC4449

    I have a few questions related to the LTC4449 MOSFET driver.

    1. Do you recommend any power supply sequencing for the Vlogic and Vcc inputs?
      1. I plan to provide 3.3V for Vlogic and 5.0V for Vcc.  The attached MOSFET bridge will have a Vin of 12V.
    2. Since the…
  • LTC4449振铃?

          如图,用LTC4449作为一个半桥驱动器,LTC4449 5脚用FPGA给一个pwm信号,2脚TS(VD_T)输出8V / 0V的电平,PWM频率 100HZ,测出TS输出波形如图所示,振铃比较严重,请问有什么办法可以减小振铃呢?

  • LTC4449输出振铃?

    用ltc4449驱动半桥,电路如图所示,用FPGA向2脚 IN 输入PMW波,频率 100HZ, 控制TS引脚输出8V / 0V电平,实际测得TS引脚波形如图所示,振铃很大,请问怎么可以减小振铃呢?
