BQ25619: BQ25619-Termination current accuracy

switch
Genius 3850 points
Part Number: BQ25619


Hi ti team,

What is the Termination current accuracy when ITERM=20mA,  ICHG>260mA, VREG=4.35V, TJ = 0°C - 85°?

Specifications write ITERM=20mA, ICHG<260mA, VREG=4.35V, TJ = 0°C - 85°C current accuracy is ITERM=20mA±10mA.

    Hi,

    That spec is not available.

    Thanks,

    Ning.

    Hi Ning，

    Thanks！

    My client had a problem testing the termination current. The charging current is set to 220mA, the termination current is set to 20mA, the SYS load is less than 10mA, and the ambient temperature is 0°-10°. At this time, the termination current will be 3mA or 50mA, and the termination current has exceeded the specification range.

    In addition, the charging current is set to 220mA, the termination current is set to 20mA, the test temperature is 0°-10°, and the SYS no-load or load is greater than 15mA and the termination current is in compliance with the specification.

    Please help to analyze, thank you!

    Hi,

    Could you please provide the following information for your observations?

    1.The operating conditions such as VBUS (voltage at VBUS pin), IVBUS, VBAT (voltage at BAT pin), IBAT, VSYS, ISYS. VBATSNS (voltage at BATSNS pin).

    2.All the register readings. The register readings help to understand the charge operating status and fault conditions if any.

    Thanks,

    Ning.
