MSPM0L1105: Current consumption estimation

MSPM0L1105: powering up with BQ76942 REG1

Part Number: MSPM0L1105
Other Parts Discussed in Thread: BQ76942,

Hi team,

BQ76942 has a internal LDO REG1 which seem to has a capacity of 45mA

Can this REG1 be used for powering up MSPM0L1105 for most of the use case?

I'm not sure with the power consumption of MSPM0L1105. But it seems to be very low power device.

Regards,

Ohashi

    Hi Ohashi,

    Yes, 45mA should be more than enough current capability for the MSPM0L in most cases.

    I'd only caution that you could approach this current limit if you were using the MSPM0L to drive multiple loads with high current requirements.
