Part Number: BQ24195

Hi,

I just know the BQ24195 will be working on PFM when the battery is below minimum system voltage setting or charging is disabled. beside of voltage, I also like to know if the output current or charge current is very small, does the charger also working on PFM? if yes, what 's the threshold?

Best Regards,

Mark

    Mark,

    The PWM and PFM mode transition current thredolds are not tested parameters so the accuracy is not accurate. The measurement with one device has PFM entrance is ~70mA PFM and exit threshold ~400mA.
