  • RE: BQ25150: min max values of ADC conversion time?

    Hi Stefan, Stefan Lintner said: what is the ADC power consumption per channel? In active battery mode, I found that, with 4.2V battery, enabling or disabling most of the ADC channels changed quiescent current consumption by approximately 1-2 uA, however…

  • BQ25150: Host controlled HW_RESET not working

    Resolved
    Part Number: BQ25150 The datasheet implies that a host controller can initiate a power cycle: "A HW Reset may also be started by setting the HW_RESET bit. Note that during a HW reset , VDD remains on" When I write a 1 to this bit I don't see…

  • RE: BQ25150: BQ25150: LS/LDO output not working on power up from battery part II

    Resolved
    In this design, its acceptable compromise that BQ25150 is in low power mode during startup and woken up with /LP or VIN since LS/LDO is not used straight after power up. For future designs, possible solution could be resistor divider and/or RC delay…

  • BQ25150: Even if the power supply is removed ,charger Vin still has 2.4V voltage

    Part Number: BQ25150 Sometimes when the power supply to the charger Vin is stopped, it is found that the charger Vin has a voltage output of 2.4V. The probability of this happening is about 1/10. So what causes VIN to have voltage output？

  • BQ25150: MR Reset

    Resolved
    Part Number: BQ25150 Hi Team, in the DS on page 24 it says The host may change the reset behavior at any time after MR going low and prior to the MR_HW_RESET timer expiring. It may not change it however from another behavior to a HW reset (Power Cycle…

  • RE: BQ25155: Drop-in replace BQ25155 with BQ25150

    Resolved
    Sorry to ask a related question on the resolved thread. I'm just exploring possible future modifications to support multiple chips. Currently, my C4 (ADCIN) in BQ25155 is connected to GND directly. What if I route C3 (IMAX for BQ25150) through C4 and…
