  • UCC27324: can UCC27324 NC pins be left floating but not connected to GND?

    TI Thinks Resolved
    Part Number: UCC27324 Other Parts Discussed in Thread: LM5111 , , UCC27624 hi team, my customer is using UCC27324 as a second source of LM5111, but the layout of LM5111 has been fixed with NC pins floating. so can our UCC27324 NC pins be left floating…

  • [FAQ] Can I Drive PMOS MOSFETs with TI's Half-Bridge Gate Drivers?

    Resolved
    Other Parts Discussed in Thread: UCC27284 , LM5111 When selecting a MOSFET, there are two different types that can be considered for either a low-side or high-side switch. There are NMOS and PMOS MOSFETs to select from. With an NMOS FET the source and…

  • UCC27527: differential signal input

    Resolved
    Part Number: UCC27527 Other Parts Discussed in Thread: LM5111 , Team, We currently use the LM5111-1MY to drive a DUAL MOSFET that in turn drives a transformer. While working through a legacy design that uses the LM5111 I have discovered we are actually…

  • RE: UC2950: High-side drives Pch, low-side drives Nch

    Resolved
    Hi Nishie-san, For a PMOS/NMOS bridge, you usually need a low-side driver, since the driver can be referenced to ground. a half-bridge driver has level-shifting designed to drive an NMOS. Our only low-side driver explicitly designed to drive PMOS…

  • RE: UCC27511: The possibility of driving p-channel MOSFET

    Resolved
    Hello Yamamoto-san, We have an FAQ on driving P-channel MOSFETs linked here . To summarize, the UVLO features of our drivers pull the output to GND when the voltage falls below the threshold, which is usually the opposite of what is desired for PMOS…

  • RE: UCC27516: Can this chip drive PMOS transistors?

    Resolved
    Hi Zhu, See this FAQ. All of our drivers can drive PMOS. All you need to do is ensure the VDD and GND pins of the driver are biased to give you your target Vgs for the PMOS. However, the drivers are mostly configured for NMOS. One thing that can…
