about low side gate driver

Hello E2E,

I looking for Low-side gate driver that it has 2-channels output and adjustable dead-time feature.
Does TI have any matched device?

Regards,
ACGUY

  • HI ACGUY,

    Thanks for reaching out on e2e,

    Typically adjustable dual channel drivers come in half-bridge configurations rather than dual low-side drivers. You can use LMG1210 which is a half bridge driver as two low-side drivers by grounding the HS pin. LMG1210 has an adjustable dead-time feature 0.5ns to 20ns. What max/min dead-time do you require? You can also use a single or dual channel driver with a LPF on the inputs to form a fixed dead-time. LMG1210 can drive MOSFETs or GaN FETs with 5V VDD drive. What gate drive voltage do you require?

    Thanks,

  • HI ACGUY,

    Do you require isolation? what application is this for?

    Other half bridge drivers that can be converted to low-side drivers with dead-time are UCC21520 (and UCC21222) as well as LM5106.

    Please let me know if you have any other questions.

    Thanks,
