Hi all,
I have a 36s PCB that contains 3xMC33771C's that read 12 cells each. I am speccing my external connection to cell terminals. As cell 12 (And 24 but will stick to just 1 for the question) need to be used for 4 functions: Cell 12 sense and VPWR for BCC 1 and CT_REF and GND for BCC2. Can I link the sense wires together?
I know you should not link CT_REF with GND and Cell 12 (CT14) and VPWR together so I have 2 spereate lines at the moment, 1 tthat goes to Cell 12+ terminal for CT14 of BCC1 and 1 that goes from the same terminal to VPWR for BCC1. VPWR is then put through a resistor to become GND for BCC2 on the PCB. Do I need to add a 3rd sense wire or can I just put CT_REF2 input pin bridged to CT14 input pin on the connector? Thank you!
