TPS1641: TPS16412DRCR ILIM and IOCP Tolerances

Asha C
Intellectual 385 points
Part Number: TPS1641

Tool/software:

Hello,

Could you please provide/confirm the tolerance info for ILIM and IOCP Levels, 

ILIM : In the datasheet  , i see the tolerance(around 25%) below for RLIM = 332kohm which leads to 30mA ILIM. Is the tolerance mentioned for range -40 to 125c, as i do not see anything in test conditions column.

My use case is around 30-50mA ILIM , what should be considered as tolerance in this case for the temp range -40 to 125c?

IOCP: In datasheet , IOCP tolerances is mentioned for 1A(which is 6%) but as per the range of IOCP we can go until 80.6kohm which leads to 204mA , what should be the tolerance which needs to considered for the minimum IOCP over the temperature range?

    Hello Asha,

    Test condition and temp range is written in 7.3 section in datasheet.

    It should be between 22% to 25% tolerance range.

    You can consider ~20% tolerance for minimum IOCP.

    Thanks
