L9963E does not work in direct SPI mode (SPIEN = 1)

I am using EVAL-9963EFrom datasheet, when SPIEN pin of L9963E is connected to VCOM and R43, R46, R57, R138, R139, R140, R141, R143 are assembled, L9963E is now ready to use direct SPI (normal SPI without isolation). 1 MCU communicates with 1 L9963E o...

Could you support for samples of ST-ONEHP? we are planning to build the prototype.

Kindly help to check and advise if the topside marking is valid and just normal.

Dear Support,Good day,Kindly help to check and advise if the topside marking is valid and just normal.Please refer to attached photo, the two devices marking is faded.

Dear support team, Siemens purchases various diodes from you and needs compliance data, which can be communicated via BOMcheck or via an Excel document. Can you please send us an e-mail contact for this purpose. Thanks for your help! Kind regards

Was wondering if anyone would be kind to review my circuitry (Vin19V@Imax 10A) that uses the VND9016AJTR device? The application note, DS & evaluation board don't explain how to calculate the appropriate properties of Rsense (10mOhm@10Wmax OK?). Thanks!

Why Minimum 125V DC Supply Voltage for STEVAL- IHM023V3 ?

I have been using the PWD13F60 dual H Bridge IC which is a great device but the EVALPWD13F60 Eval board is limited to 2A_rms even though the IC is good for 8A DC due to thermal limitations of the eval board which is a shame as I really need to get a...

Hello! I have an STEVAL-ISV020V1 module. Is it possible to modify this module in order to charge a supercapacitor with a minimum voltage of 2.2V and a max. voltage of 3.8V?

From documentation I can not figure if it is possible. Do you have any configuration of resistors(R4,R5,R6) in order to modify Vuvp and Veoc?

I would like the failure rate for St Micro part numbers Viper26HDTR and Mastergan 1TR. Thank you very much. Ken Neubeck Reliability engineer, NAI
