Part Number: LM5105 Other Parts Discussed in Thread: TINA-TI I have an issue with the LM5105.
It is shooting through when the HO output is switching on, the LO turns on slightly.
I have simulated in TINA-TI and have posted an video explaining the…
Part Number: LM5105 Hi Expert team ,
Please let know if any possibility of double time marking on DIE. Kindly confirm the acceptance Criteria.
Suggest us is it acceptable with a document.
Part Number: LM5106 Other Parts Discussed in Thread: LM5105 , , LM5104 Hi team, my customer is looking for an alternative to LM5105 due to supply issues. One alternative is LM5106, which does not have the bootstrap diode integrated, so it seems that it…
Hello Oskar,
It is possible that there is ground bounce from the driver ground reference and the controller ground which is causing the issue. Also you need to be careful in connecting the scope probes to avoid noise pickup from the test setup. Connect…
Part Number: LM5105 Hello,
I'm using LM5105SD gate driver for implementing 3 phase H-bridge motor driver, I'm using BSC046N10NS Infineon FET, the PWM frequency is 18kHz.
during activation of the circuit, i experienced upper FETs burns out. In the…
Part Number: LM5105 Dear Team,
Could you please help with my customer question below ?
When I ran the PSpice model the dead time doesn’t change even if I change the RDT resistor. Is this correct behavior ?
Best regards,
Nir.
Hello Erik,
Getting the parts and the boards has taken longer than is typical, I still have not received as of Friday. I will confirm when I go to the office tomorrow.
The other suggestion would be to determine the dead time that is adequate for the…
Part Number: LM5105 We designed the Half-Bridge MOSFET Driver circuit using LM5105 as Figure 1. We are trying to drive in 60Hz Acrive-Low, High-side 16.6ms and Low-side 1.8μs continuously. And other information is described below. VDRV_L: Referential…
Part Number: LM5105 Other Parts Discussed in Thread: UCC27282 Is there a way to lower the LO and HO gate drive voltage on the LM5105 device?
I am currently testing out a circuit that uses the LM5105 to drive the FETs of a H-bridge (see schematic). The…
