Dear Sir,

We are using BQ25601RTWR part in one of our design.This part is industrial grade part.

Currently we are looking for automotive grade component.

Request you to please suggest the alternate part for above part with Automotive & AEC Qualified.

    Hi Suhan,

    The only auto qual switching charger of which I am aware is BQ24105-Q1.  It does not have powerpath.  Can I get more information on our application, such as input voltage, battery capacity, host controlled via I2C or standalone resistor control?

    Regards,

    Jeff

    Dear Sir,

    Can I get more information on our application, such as input voltage, battery capacity, host controlled via I2C or standalone resistor control?

    Application : Vehicle Tracking Device

    Input Voltage : 5V

    Battery Capacity : (Nominal Voltage-3.8V & Max Voltage-4.2V) 

    In BQ24105-Q1 Battery pack voltage is 12.6V . As per our design recommended battery pack voltage is 4.2V.

    Request you to please suggest the Automotive & AEC Qualified battery charger IC with BQ25601RTWR spec.

    Regards,

    Hi Suhan,

    Unfortunately, we do not have an automotive version of the BQ2560x or similar family.  The BQ24105-Q1 switching charger can function from VCC down to 4.35V and the output feedback resistors can be configured to charge a 4.2V battery.

    If your current is <=1.5A, you might consider linear charger BQ24075-Q1. 

    regards,

    Jeff

    Dear Sir,

    For BQ24105IRHLRQ1 part operating temperature is  -40°C ~ 85°C.

    How we can consider this part is automotive grade component?(normally automotive temperature grade is  -40°C ~ 105°C)

    Also please confirm whether  BQ24105IRHLRQ1 part is AEC qualified component?

    Regards,

    Suhan Shetty

    Suhan,

     

    TI's Q1 products are qualified in accordance with AEC-Q100. The AEC-Q100 temperature grades are given below:

    Grade               Ambient operating temperature range

    Grade 0                -40°C     +150°C

    Grade 1                -40°C     +125°C

    Grade 2                -40°C     +105°C

    Grade 3                -40°C     +85°C

    Grade 4                -0°C        +70°

     

    The BQ24105–Q1 is AEC-Q100 qualified with Grade 3.

    Regards,

    Dear Sir,

    One more general query, Whether all AEC qualified components are automotive grade component?

    Regards,

    Suhan,

    As I mentioned above, AEC qualified means automotive grade.  There are different temp ranges that are automotive grade.

    Suhan,

    Unfortunately, I do not support either of products.  They each are supported through different groups at TI.  I recommend create 2 new posts, using those part numbers in the post for fastest response.
