Part Number: UCC21520 Other Parts Discussed in Thread: TIDA-00366 , UCC21550 , UCC21551 Hello supporter,
I used UCC21520 for a half-bridge 3 phase to control the motor. Initially, everything operates normally but a surprising error happens (short circuit…
Part Number: UCC21520 Hi team,
My customer use UCC21520 in their project, the test waveform of the PULSE - M2 shows that the top of the pulse is not flat. Could you please help give some suggestion to improve the problem?
The schematic shown below, thank…
Part Number: UCC21520 Dear TIer,
I have question about single / two channel ios-gate driver.
Why single channel iso-gate driver no use bootstrap circuit in main popular half bridge design?
It looks like a PWM IC with two auxiliary lines is used, whereas…
Part Number: UCC21520 Dear Specialists,
My customer is considering changing UCC21520 and has questions.
I would be grateful if you could advise.

Part Number: UCC21520 Dear TI team,
I am using Dual channel gate driver IC "UCC21520AQDWRQ1" to drive MOSFETs of Phase Shifted Full Bridge Topology (Input voltage is 400 Vdc and output voltage is 175 Vdc). During turning-off of the MOSFET, I have observed…
Part Number: UCC21520 Hi Team,
We see that there is one 600V diode and resistor(D1/R15) in serial as below picture shown for UCC21520 EVM circuit, may I know what's the purpose for them? Do we need to add them for customer's circuit design?

Part Number: UCC21520 Hi Team
RD is still surveying driver IC.
Currently We will use 3 pcs UCC21520 to the "soft-start system for scooter " (for Three-phase electrical power ).
Not sure if we have intergreted solution ? THX
Part Number: UCC21520 Hi,
I am planning to use UCC21520 in half bridge configuration similar to the one shown in the IC datasheet in Fig. 10-1. However, instead of using bootstrap configuration I want to use the bais configuration shown in Fig. 10-3 as…
Part Number: UCC21520 Hi TI experts,
Is UCC21520 suitable for back-to-back (MOSFET) operation ? The idea is to use it as bidirectional switch for AC line (thanks to its isolation feature).
If yes, is there a reference design somewhere ?
If no, is there…
Part Number: UCC21520 As per the Datasheet, if the DT pin is left open: The default dead time is from 0 to 15ns Maximum.
Can you confirm that by keeping the DT pin Floating, will set the dead time between OUT A & OUT B to maximum 15 ns.
In my application…
