TPS4800-Q1: TPS4800-Q1 over current protection tollerance

Part Number: TPS4800-Q1


We are designing a medical system where the current into the system should be limited between 14A and 16A (absolute max). The datasheet of the tps4800-Q1 is vague about the tollerance on the Iscp level. The datasheet hints that we can improve the tolleance, but we cannot make a proper calculation of this current limit.

Can you give more information of the tollerances in the system (for example the comparator offset tollerance and the gain tollerance)

 

  • Hi Jeroen,

    The only tolerances for the ISCP that I can give you are in the data sheet:

    The I short circuit protection tolerance should be able to be found based on the SCP threshold values which is the voltage drop over the SNS resistor

    Best Regards,
