Part Number:DRV8303
HELLO the problem is my DRV burned after a fews minutes.
The VM pin have 9 V (the minimum in data sheet is 8.5V ) this is because i need to communicate with them over SPI to read and write the register.
i check everything on my board and no have short circuit is a custom board.
I do this test when I do not have the DRV8308 chip soldered on the board my current in power suply is 0.01A or 0.00A
when i soldered the chip on board is ok with the power suply i put 3.3v on enable pin in DRV8308 and after maybe 5 or 6 minute they burn ...
the output from chip don't use and the Vreg i don't use, in this moment i want communicate over SPI without burned the chip.
I have the Vreg = 5V and Vint =1.79V before they burn.
is possible i wrote bad registor on chip?? like turn ON two output in same precise time and they burn?
