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 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 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: SN74LVC2G06 Other Parts Discussed in Thread: UCC21520 , SN74LVC2G04 Hi,
I am testing a PCB that includes a SN74LVC2G06 inverter IC and a gate driver IC UCC21520 to drive two power MOSFETs. The inverter IC is incorporated with associated recommended…
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 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-Q1 Dear team,
1. In below spec, input limit is 50mW. Does this limit come primarily from the ESD diode of the input pin?
2. If an application exceeds this limit and causes the chip to fail, will it cause the insulation between primary…
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…
Here is the additional detail from the output window.
I used either the Unencrypted Pspice Transient Model or the regular Pspice transient model from the TI UCC21520 site. I will try both and see if I still get the same message. Thank you…
