Other Parts Discussed in Thread: INA302-Q1
My customer has a special requirement for 12V BMS system. The source of Q1 connects to 12V Li-ion battery, and the source of Q2 connects to system load. When the system works normally, the current direction is from 12V BAT to Load; when the Li-ion battery needs to be charging, the current direction is from Load to 12V BAT. Every direction needs to include reverse polarity protection, so we are considering to use two LM7481-Q1 to drive one B2B switch together. We will use EN pin to control the direction, and only one LM7481-Q1 is working in each direction. My questions are as below,
1. Is below architecture feasible?
2. When the direction is switched, how long does our device take to switch?
Thanks & Best Regards,
