Part Number: UCC27714 Hello,
I want to drive one MOSFET to fix the BUS voltage by the UCC27714. This has two input pins HI and LI working with two PWM signals like a datasheet circuit. In my case, I have just one PWM signal that I applied to the HI and…
Part Number: UCC27714 I am interested in using a high side gate driver (ex. UCC27714) with an N channel MOSFET to act like an electronic switch for a high voltage operation. I've researched a bit about high side gate drivers and noticed that they have…
Part Number: UCC27714 Hello,
The datasheet of UCC27714 says the part can source a max of 4A.
1.Where does it source it from ? VDD? or from the high side source?. VDD is not robust enough to provide 4A even if its just a spike to charge the mosfet capacitance…
Hey Shankar,
I am going to close this thread at this point under the assumption that this has been resolved.
If this has not been resolved, please reopen this thread and update me on the current status so that I can help this get resolved.
Thank you, …
Part Number: UCC27714 Is UCC27714’s VSS and COM the same GND? Customers want the two separate half-bridge drivers, they want to have the different GND between low-side GND and input GND.
They don’t use isolated driver because the cost of isolated…
Part Number: UCC27714 Hello,
I want to switch a High-Side and a Low-Side N-Channel Mosfet with the UCC27714, but the COM Pin is not tied to GND. Instead it is tied to a negative voltage to the potential -Vdd at the source of the Low-Side Mosfet. The load…
Hello Faiz,
It sounds like there could be a damaged UCC27714 which results in excessive current when the outputs start switching, or there is a low resistance fault on the Mosfet gate to source, which results in excessive average current from the driver…
Part Number: UCC27714 Figure 1 is my simulation schematic
Figure 2 shows the HO and LO output waveforms
Figure 3 shows the driving waveforms of HO and LO when I increase the H-bridge supply voltage to 300V
I want to drive load L1 through the H-bridge…
Part Number: UCC27714 Other Parts Discussed in Thread: UCC27710 , UCC27712 Hi team,
My customer is evaluating half bridge driver over 150V, and they require mainstream and low-cost model.
I'm promoting UCC27714 to the customer. Do you have better suggestions…
