Part Number: LM5109B-Q1 When testing the circuit, the customer found that when HI(pin2) and LI(pin3) have PWM input signal, there was no waveform at TP161 (pin-HO) and TP149 (pin-LO). When he set pin-HI to a low level for a while, the voltage at pin-HO…
Hello Robert,
Your understanding is correct. The two channels are independently controlled by INPUT. However, it must be guaranteed that VDD-VSS and VHB-VHS are always within the safe UVLO region. for example, VDD-VSS, VHB-VHS must be higher than 8V…
Hi Bjornar,
Thank you for your interest in LM5109B. The terminology "disabled" refers to setting the respective output (either HO or LO) to the low state, and not to a high impedance or open state.
If this post has addressed your question, please…
Other Parts Discussed in Thread: LM5109B Hi Sir
My customer find here have some LM5109B damage(Vcc short to GND) in their design board.the circuit pls refer enclosed file.
i find it Cboost is use 2uF and CVdd is 100nF. i think it Cboot is to high…
Other Parts Discussed in Thread: LM5109B Dear Sir
May we know LM5109B have prevention short through function(Vhi/Vli input Hi at the same time then will no output in Voh/VoL)?
or have other gate driver can support?
Best regards,
Bogey
Part Number: LM5109B-Q1 Other Parts Discussed in Thread: UCC27212A-Q1 Hi Team,
Customer is looking for auto HB gate driver which is capable of Vin_min=7.5V, system operating voltage.
LM5109B-Q1 is good for candidate, but recommended operating range…
Other Parts Discussed in Thread: LM5109B , LM5109A Dear TI Sir:
I have a question for LM5109A and LM5109B that is LM5109A/B have Cross Conduction Prevent Logic Function?
When the timing or logic of HI and LI are wrong, LM5109A/B can tuen off HO…
Other Parts Discussed in Thread: LM5109B , LM5109A Hi, does anyone know the difference between LM5109A & LM5109B? Thanks a lot.
I compared the datasheet and can't find any difference....
