Hello everyone, I am trying to use the PWD13F60 full bridge driver IC to drive an acoustic transducer. I am using the corresponding evaluation board for test purposes. I have a question about the IC. What exactly is the purpose of the SENSE pins?

I noticed the pads of these pins are very small. I'm a bit worried this is critical with high-current thoughput. For my application current peaks might exceed >5A for couple us. Pads like GND, VS and OUT are very large in comparison..

I am referring to L6491 EVM from ST Microelectronics. It is driving 3 Phase motor MOSFETS. Is there any equivalent isolated motor driver or Can I isolate the PWM signals coming from the uController using optical isolation?

Is this normal behavior for the L6491 Smart Shutdown signal/system?

Using 2xL6491 in a full H-Bridge inverter for a PMDC motor, PWM switching frequency is 32kHz. With the smart SD threshold set low to verify the functionality, we see what appears to be skipped PWM pulses most likely due to the shutdown system blockin...

Hi Community, 1. Do we have any parts similar to LTC3588-2 (comprising both rectifier and boost circuit) for Microwave power harvesting? 2. Is there any product replacement for EFL700A39, currently available to purchase? Thank you in advance.

Hi i Need STPS24045 safety area that diode per channel non repetitive forward current at 28V@200A 1 second durability. Can you share this document or durability data? Best regards

Resolved! hi and good day 5 inverter boards have been sent to me and There is a SMD part(8-pin) on the boards with the code( 293 GZ513) and made by ST company. Please tell me what's the name of the part and the technical code of the part thank U SO much

STEVAL-ISA147V3 project source for MCUs.

Hello forum! I purchased the STEVAL-ISA147V3 for evaluation. I am glad to report it powers on and drives a load. However, the code is not up on the product page. Can you please send it?There is an older question on the forum about this, but no reply ...

Is it possible to buy a STPMIC1E programming dongle without the whole eval kit ?

My colleague already has the kit so I'm only interested in monitoring and the simplest tweak. A whole dev kit would be a waste.

STPM32 UART Arduino Lib

Hi,is there a Arduino Library for the STPM32 Measurment IC?

Unable to use the EVAL6235Q alone or with the STEVAL-PCC009V2

Description:This is what we did with the EVAL6235Q to use the external speed loop connector to drive a BLDC motor:1. On the power supply connector, we attached 12 V.2. We connected our BLDC motor to the 3ph BLDC motor connector.3. We ...
