BQ25300: Is this part resilient to supply drift, supply ripple, and temperature?

johny radio

Part Number: BQ25300

Assuming Vin and temperature remain within recommended operating conditions, is this part resilient to:

changes in ambient or internal temperature?
ripple in supply voltage?
drift in supply voltage?

Specifically, Will the charge voltage regulation remain steady, ripple-free, and correct, even if there is ripple or drift in the supply voltage?

Hi,

It depends. Please refer to 8 Specifications on the d/s for the Absolute Maximum Ratings and Recommended Operating Conditions.

Thanks,

Ning.

Hi,

The device should not get damaged if operating within the recommended operating range.

Thanks,

Ning.

Hi,

The charger is basically a closed-loop control step-down DC-DC converter. It should be able to settle after responding to input voltage transients.

Thanks,

Ning.

but ripple in the supply isn't a one-time transient, it's continual.

Hi,

The transient responses are dependent on the charger design, the operating conditions etc. Please evaluate the device under your specific application scope and see if the device meets your requirements.

Thanks,

Ning.
