I have to design a complete Battery Management System for a application with below specs:

1. Pack voltage: 72V (nominal) , 70V-84V range

2. Capacity: 80Ah  (20 cells in series & 25 in parallel,, 20S25P)

3. Cell chemistry: NMC (Lithium , 18650)

4. Cell Voltage: 3.6V(nominal) , 3.5V-4.2V Range

5. Cell capacity: 3.2Ah

6. OverVoltage cut off: 4.2V/cell

7. OverVoltage release: 4.0V/cell

8. Undervoltage cut off: 3.5V/cell (80% DOD)

9. UnderVoltage Release = 3.6V/cell

10. Continuous Current at max load: 80A

11. Peak laod current: 150A for 10 seconds

12. Continuous charging current: 30A

13. Overcurrent in Charge/discharge Protection

14. Short Circuit in Charge/discharge Protection

15. OverVoltage/UnderVoltage Protection

16. Capacity Gauging(SOC/SOH)

17. Digitial Communication: RS485, CAN

I have checking MC33771, is there any reference design? I need datasheet for this IC .

Thanks & regrads

Dear Deepak,

Thank you for your interest in our battery cell controllers!

Unfortunately I am not allowed to share the MC33771 data sheet unless you have an NDA signed with us. To sign the NDA, please contact our local distributors.

Regarding the reference design, there is the KIT33771SPIEVB.

Best regards,

Tomas
