Posted on March 12, 2016 at 19:10 Hello. I use L6470H chip. I found a issue of the chip. I want switch mode BUSY and SYNC in my program to control of the step clocking. I can write ''1'' to SYNC_EN bit of the STEP_MODE register. BUT I ca...
Posted on March 12, 2016 at 01:06I have some L78L15ACZ's that do not seem to be working, or perhaps there is some required external component/circuit configuration that is missing? The output is remaining approx. a diode drop below the input...beyo...
Posted on March 10, 2016 at 17:41ST L78M24 DPAK (PFA Datasheet) has input voltage max of 40V, we are operating the part at about 39V which is very close this upper limit. Our average circuit current consumption can go upto 66mA. Actual Power Dissipa...
Posted on March 10, 2016 at 11:39Hello,I'm using 6 IGBT's part no. STGF10NC60KD in a typical three-phase inverter application and I have designed a short circuit protection to prevent IGBT damage when 2 phases of the motor becomes accidentally short...
Posted on March 08, 2016 at 11:29We have to prepare an H-Bridge to supply a resistive load in both current directionsWe plan to use 4 N-channel MOSFETs and we would like to use L6743 as a HB driver for each couple of MOSFETS But we want to use in al...
Posted on March 06, 2016 at 10:45(Text was missing in my 1st post. Did not work from mobile?)Hi - does someone know whether the two LDOs on the SPV1050 will supply power even when the charging circuitry is disconnected from the battery (!BATT_CONN i...
Posted on February 18, 2016 at 11:40We have an issue related your stepper motor controller L6470.We are working with two of your evaluation boards: EVAL6470H-DISC and EVAL6470PD and we had two critical situations with two boards, one of each. In tho...
Posted on February 11, 2016 at 13:22Hi,I have a question regarding L6470 protection. Are any protection diodes needed on the L6470 outputs?The datasheet doesn't mention any protection and the evaluation boards doesn't have any. This is the case also...
Posted on January 25, 2016 at 10:29Questions on STEVAL-IHM038V1 We are planning to design a BLDC ceiling fan controller board based on the STEVAL-IHM038V1 evaluation board. (http://www.st.com/web/en/catalog/tools/PF255633) We have some technical q...
