Part Number: LM5109A Other Parts Discussed in Thread: LM5109 , LM5109B Hello Team,
I am using the LM5109A Half Bridge Gate Driver in design. I need to calculate the current will souce by this device.
I am doing the current calculation on VDD as well as High…
Part Number: LM5109A Hi, we have a small inverter for a BLDC motor that uses the LM5109A. Commutation is six-step, and at temperatures above about 75C, the voltage on the charge pump capacitor is dropping about 3X faster than at room temperature. It is…
Part Number: LM5109A I am concerned about the possibility of an undefined state when both inputs are low for a long time. Under this condition, I wonder if FET or circuit leakage could pull the top gate positive slightly. If so, then the gate could eventually…
Part Number: LM5109
There have been questions regarding the differences between the LM5109A and LM5109B 100V high-side low-side drivers.
The pinout, available packages and parameter specifications are the same for the LM5109A and LM5109B. So the LM5109B…
Part Number: LM5109A Other Parts Discussed in Thread: LM5109 , LMG5200 Hello,
I'm using 3 LM5109A to drive 3 phase 200W BLDC motor. I've included schematic with component details.
VIN to the power MOSFET half bridge stage: 20V-33.6V (Battery power…
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…
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: 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: LM5109B Other Parts Discussed in Thread: LM5109A Hello,
Today we are using LM5109A, but we might change to LM5109B.
What is the main different between these parts? They seems very similar for me.
Only different I see is that LM5109B datasheets…
