When TPA3251 is running in 1XBTL+2XSE mode, I only use one BTL and one SE channel (DC power supply is 36V), the other SE channel is not used, is this suitable, what are the risks?
Hi
For unused SE channel, the BST cap still needed, otherwise will trigger OC error. The unused SE channel will still output PWM, may a little affect the EMC results.
