Hello, I have some quesions about the SM72442, especially about the SM3320-BATT-EV.
1. On the SM3320 board is a comperator U11B, which shutdown the SM72442 by increasing the output voltage about a threshold. I think the SM72295 has the same feature inside (OVS and OVP Pin)?
2. On the SM3320 board is a jumper (Burn In) connectet to NC4 of SM72442, what is the function of this jumper?
3. On the SM3320 board is a comperator U11A, which can switch the output current between two values. But for my understanding its also possible two change the output with Bit 30:39 in Reg 3 ?
4. On the SM3320 board is a start up circuitry, to start up the SM72442 in Boost Mode. Why need a buck/boost converter an external start up?
5. If I only use the boost mode, can I can omit or bypass transistors for buck mode?
Thanks
Julian
