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

    Juan Ospina

    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…

    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…

    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?
