Part Number: DRV8244-Q1 Other Parts Discussed in Thread: TVS2700 , Tool/software: Hello,
I have been working on a board that controls a solenoid using the DRV8244 motor driver and a TVS2700 for surge protection. We had failures occur while "coasting…
Part Number: DRV8244-Q1 Tool/software: Hi
I have a question about the spice model of DRV8244-Q1. I am currently running “DRV8244HDGQQ1_TRANS” on LTspice to check the operation of DRV8244-Q1. The picture below shows the model and waveforms, but I have…
Part Number: DRV8244-Q1 Tool/software: Hello Colleague
In my application, I need a half-bridge driver to control external lock motor. The feature of the lock motor is normal current 5.5A(@200ms) and stall current 15A(@500ms).
I would like to use the…
Part Number: DRV8244-Q1 Tool/software: While performing a short-to-battery (SC-to-BATT) test on the DRV8244 (configured as independent half-bridge), the peak current measured was 50.3 A before the driver was disabled. However, according to the datasheet…
Part Number: DRV8244-Q1 Tool/software: Hey team,
Do we have any layout guidelines for the VQFN package? I see we created an EVM for the VQFN, but it doesn't have many great captures show layout.
Thanks,
Cam
Part Number: DRV8244-Q1 Tool/software: We use the Hardware vaiant 8244H.
When we release nSLEEP from Low (standby) to High (3.3V), nFault immediately get activated (pulled Low),
Mode is connected to 8k2 resistor (independend mode), ITRIP goes to…
Part Number: DRV8244-Q1 Tool/software: Hi Expert,
Whether DRV8244-Q1 SPI support 3.3V logic level communication?
Customer's simple schematic is like below. Whether VDD need to change to 3.3V ?
Part Number: DRV8244-Q1 Tool/software: Hi.
I have a question about the OCP operation of DRV8244-Q1. In PWM mode, I am aware that the overcurrent protection is Hi-Z for both Out1 and Out2 as far as I read the datasheet, but am I wrong?
As part…
Hi Matteo,
Thank you for your post.
Matteo Scalabrini said: SPI Timing : Are there any specific timing nuances that are commonly overlooked when dealing with DRV8244 that could cause the chip to be unresponsive?
For every SPI register transaction…
