Hi
The customer design with two EMB1428, without the use of a 1499 chip. The following designs are made for the seven pins:
DIR and DIR_ RT has made a reverse circuit, and DONE and EN pins have also made a reverse circuit,
Three FAULT pins are designed as interlocking functions for two EMB1428 chips. Interlocking is for safety reasons. When one EMB1428 is closing a certain channel, the switch controlled by the other 1428 must be fully open. The FAULT0 pin is controlled through GPIO, and the FAULT1 and 2 are connected to GND. This design currently cannot achieve the effect of two chips interlocking under testing.
Please give some suggestions.
Thanks
