Part Number: LM5108 Hi guys, working with a customer on this device. Is there a spec for propagation delay from the EN pin to the HO pin?
Example, what's the time delay from V_EN < 1.65V to HO = HS + 0.5V (or something similar).
Thanks!
Part Number: LM5108 Hi,
I am considering creating a non-insulated synchronous booster circuit. So I would like to ask you a question. Could I use the LM5108 half-bridge gate driver as a gate driver for a synchronous booster circuit? If so, are there any…
Hi Oliver,
I am not the expert for the LM5108 but I am quite sure that the boot circuit (Diode and Cap on HB/HS) will be required on the LM5108 to generate the gate signal for the high side FET.
If required you can enter a new thread and ask about that…
Part Number: LM5108 Other Parts Discussed in Thread: UCC27282 Hello,
We are evaluating the LM5108 and had a question on the Negative Voltage Transient capability of the HS Pin.
The abs max voltage range on HS pin is -5 to 105V. Is the -5V a DC voltage…
Part Number: LM5108 Hi team, working with a customer on this device, had a few questions on the internals:
Why don’t we measure any resistance on the LI and HI pins? Can you tell us the value of the resistors circled in red?
When the EN pin is…
Part Number: LM5108 Other Parts Discussed in Thread: LM5106 , LM5105 Hi team.
I'd like to know how to use LM5108 when there is one input PWM.
Could you give me some advice?
1. If we can use LM5108 when there is one input PWM,
Please tell me the…
Part Number: LM5108 Hi HPD! Question about this part - does this part have a fixed duty cycle at 50%? I see that it's max 50% but not sure if this is fixed or not. Also, is this self-oscillating? Not able to tell from the datasheet.
Thanks so much…
Hello Grady,
Thank you for supporting the LM5108 with your customer. I did look up the Mosfet part number and I see that the gate charge is not very high at 23nC and the Vds rating is 40V. So the LM5108 has adequate gate drive current to drive this Mosfet…
