MISO line always low

I have tested AutoDirver board(L6470) with Arduino and everything worked.When I use Toradex Colibri EVA board (Imx 7) to control the AutoDirver board(L6470), I cannot get any response from L6470. The MISO line always low. Can you give me clue on how ...

SPI Electrical characteristics

Based on L6470 datasheet -> 3. Electrical characteristics -> SPI ->tholCS Chip select hold time min 10 ns.Does 10ns is correct value? I searched from google, the following link sayshttps://electronics.stackexchange.com/questions/152700/spi-chip-selec...

Could you please review that power supply design using LDO LDL212PVR.

VNQ500 burns out

Hello, We are using the VNQ500 in our board to drive loads at 24V. While testing our board the VNQ500 causes troubles and we noticed high voltage going back to the inputs of the MCU. Our schematic is pretty simple: VCC, CE and EP are all connected to...

VNH5050 diag pins and pwm input

I am designing a quad motor controller using 4 vnh5050. The motors will be controlled independently through INA1 - INA4 & INB1 and INB4 signals from uC.In order to keep pin count usage down:1) Can I connect the DIAGA and A DIAGB pins together and ...

VNQ500 Input High Voltage ambiguity

Hi,We will use VNQ500 in our circuit but I cannot be sure on Input high voltage value. In datasheet:Table 7 says Vih = 3.25 VoltsFigure 15 says Vih = 2.8 Volts and decreases with increasing temperatureWhich value should I take into account. Is it eno...

Is the X-NUCLEO-IHM08M1 inverter compatible with any STM32 NUCLEO board?

Is the X-NUCLEO-IHM08M1 inverter compatible with any STM32 NUCLEO board? Or is it only compatible with NUCLEO-F302R8 NUCLEO-F401RE?In all the documentation I have seen it is used only with these boards. I need a better board such as the NUCLEO-H743ZI...
