| Poroit:
I am doing a teardown of a Powerland 48V Li Battery Charger. The Charger contains a MC9S08PA4 which I assume is the charging controller. I have traced connections from to battery connector back to Pins 7 & 9 of the MC9S08PA4. Can anyone suggest the type of signals I should measure on these pins as I can only measure DC Voltages at the battery connector? |

Its just a 8 bit cpu with the usual add-ons https://www.nxp.com/docs/en/data-sheet/MC9S08PA4.pdf pin 7 & 9 are labeled as data ports so you could expect 3.3 / 5v & 0 v depending on what voltage it is running on it may be data from the BMS or it could just be simple logic levels . |
