Hi Jiatu,

You should be able to power the MSP430FR2155 using REG1 and REG2 from the BQ76952. The REG1 and REG2 LDOs can provide an output current of up to 45 mA each. Their short circuit detection occurs at 80 mA. Additionally, TI has a reference design using the BQ76952 and MSP430FR2155 together that you may find helpful. I will attach the link here: TIDA-010208 reference design | TI.com.

Best,

Andria
