Using the NVM configuration utility for the STEVAL-ISC004V1 seems to program fineHowever regardless of what I am writing the to the NVM, the source capabilities on the device dashboard never change and always show 3 PDOs for 5, 9, and 15 volts.
Hi,I would like to use the evaluation board STEVAL-IME014V1B to drive piezoelectric transducers for medical applications. Does the evaluation module include a built-in H-bridge for direct drive of ultrasound transducers? May I directly connect the de...
I can't find the Datasheet of this component, any help?
We currently use the WLC38, but wish to use the WLC89. Our sales provided the full datasheet, and is ordering samples of the STWL89 for us. However, there are no more evaluation kits available.Can the eval board reference design files and/or gerber f...
I have seen recommendation for by pass capacitor to be 10 times the boot strap capacitor for Mosfet driver IC's. When i verified the schematics of mb1419-g431cbu6-c01_schematic The Boostrap capacitance value is 1uF but the By pass capacitance value ...
Original title: MOSI is not responding in SPI interface TI C2000 MCU & L9026 Edited for clarity. Hi All, We are having SPI interface between TI C2000 MCU (TMS320F28P659DK8-Q1) and High Side Driver(L9026) the Our Target Board. Here are some observati...
Hello ST,Im using STNS01 as a power source in two of my different project prototypes. Unfortunately booth are facing the same problem. When the pcb was produced LDO/charger worked as intended. However after many battery and usb disconnection durring ...
Dear allI have built up the circuit of STEVAL-ISV019V1. I want to conserve power over one night in a supercap connected to VSTORE. With the 3V3 LDO enabled but no load present, the SPV1050 seems to draw about 7-8uA.Is it possible to bring it down to ...
Hello,I created a custom board using the TCPP03-M20, based mostly on the NUCLEO H7S3 schematic.The only differences are:* My uC is using 1.8V, so the EN pin only gets 1.8V* VCC_VCONN is supplied with 5V instead of 3.3V* I use a single power path (usi...
Hi all,I have a board designed using the STWLC38 as the Qi Rx. An ESP32 is the host controller using I2C to configure the STWLC38. The communication works OK and I can set and read various registers.I have two questions on this configuration:The STWL...
