BQ25185: Temp vs output

Part Number: BQ25185

Tool/software:

Dear team,

Please provide data/ graph of BQ25185 with respect to temperature vs sys load, when battery present (one condition) and without vin condition.

  • Hello Amith,

    Please refer to Figure 7-4 in the BQ25185 datasheet for SYS load regulation curves at different temperatures.

    When only a battery is present and no adapter is connected, the linear regulator will not be active, so you're not likely to see much change in device temperature. The power dissipation in battery-only mode is simply P = I2BAT * RDS(on, BATFET).

    Best regards,

    Alec Lehman
