Part Number: LM5109B Other Parts Discussed in Thread: LM5109 Hello,
checking the MPPT charge controller reference design for 12- and 24-V solar panels a RC filter has been added between the mcu and LM5109.
Is this RC (or only R) suggested when a 3.3V mcu…
Part Number: LM5109B Other Parts Discussed in Thread: LM5109 Hi,
I have LM5109B and i want to select MOSFET for this.What is maximum rating of MOSFET gate charge(Qg) as i want to drive MOSFET through LM5109B.
Can i connect MOSFET with Qg=400nC on output…
Part Number: LM5109A Other Parts Discussed in Thread: LM5109 ,
I've got 3 LM5019A gate drivers setup to drive 3 half-H MOSFETs in a 3 phase BLDC driver.
We've got 1A 12V supply shared between the LM5109. Logic levels inputs at 5V. 0Ohm output to gates…
Part Number: UCC27714 Other Parts Discussed in Thread: DRV8412 , LM5107 , LMG1205 , , UCC27712 , UCC27282 , LM5109 Hello team,
Customer application is a device that can run up to 48Vdc and near 50Amps. They use PWM controls to vary the voltage going to the…
Part Number: LM5109A Other Parts Discussed in Thread: LM5109 , , UCC27712 , LM5109B Hi I'm planning on using the LM5109A to drive a couple of low Rdson MOSFETs. The two MOSFETs are configured to drive a solenoid from automotive voltages. Solenoid manufacturer…
Part Number: LM5109A Other Parts Discussed in Thread: LM5109 I am using LM5109A to drive IRFU3607(power MOSFET) in a BLDC motor controller. The PWM is generated through a microcontroller. The motor is a rewind motor that takes up the excess liner. The…
Bryan, good to hear from you.
A push pull controller can drive; push pull Half Bridge Full Bridge
So the UCC28089 could work for your full bridge design. I made a sketch as an example.
UCC28089 has 2 outputs, A B A drives top left, bottom right B drives top…
Hi shuli,
Peak drive current LM5109A is only 1 amp, datasheet AMR list any sink or source pulse width MAX? Notice 4R87 LO/HO @FET gate typically cause higher (peaks) than 1 amp in other gate drivers. Also notice very high voltage spikes on trapezoidal…
Hello, Brett
Thank you for the answer. It seems second approach is used in C2000 Digital Power BoosterPack. They use EPWM4A,EPWM5A signal pair to drive LM5109.
I leave this thread open,so later I will ask a couple more questions on this topic.
In which…
