Tool/software:
Hello,
I’m using the DRV8262EVM with an STM32F446RE and I want to run it in dual bridge mode (OUT1/2 + OUT3/4).
My goal is to read both current sense outputs IPROPI1 and IPROPI2 separately with the STM32 ADCs (PA0 + PA2).
I have modified the EVM jumpers/solder bridges as shown in the attached picture.
My questions:
-
Did I set the jumpers correctly for dual bridge mode? (I removed J19, connected J18 = IPROPI1 → STM32 PA0 and J20 = IPROPI2 → STM32 PA2)
-
For VREF1 / VREF2: Do I need to drive them separately, or can I tie both to the same external 1.65 V reference?
-
Is my wiring for MODE1 / MODE2 / nSLEEP correct to ensure the device enters dual bridge mode at startup?
-
In this configuration, should I expect each IPROPI pin to represent the current of its respective half-bridge (OUT1/2 vs. OUT3/4)?
Right now, my STM32 ADC values are always close to 0, so I suspect I might have miswired VREF or IPROPI.
