  • DRV8305-Q1: question about UVLO function

    Resolved
    Part Number: DRV8305-Q1 hi expert For ULVO function in datasheet, i have two questions Q1: How can i understand the parameter of PVDD falling and PVDD rising? Let us assume PVDD is 10V now, when PVDD is rising to 42.5V(10V+32.5V( shown in datasheet )) because…

  • DRV8305: Will DRV8305 shoot through protection prevent cycling of low side switches without cycling hi side?

    Resolved
    Part Number: DRV8305 I have a 3phase BLDC motor driver using DRV8305. During deceleration, I'm considering closing only the low side switches (all 3 simultaneously) to perform eddy current braking while using low side shunts to monitor the current so…

  • RE: DRV8305-Q1: VDS_OCP

    Hi Kura-san, kura said: Is it okay to assume that the charge pump normally does not drop to 5.3 V (= the charge pump's low voltage protection does not work) within the range of PVDD = 4.4 to 45 V? The specification in the register setting is 4.9V typical…
