TPS1HB08-Q1: Question about Current Limit Pin

Don Edvalson49

Part Number: TPS1HB08-Q1
Other Parts Discussed in Thread: TPS4H160-Q1

On this device (TPS1HB08AQPWPRQ1) the data sheet says that the current limit pin should be tied through a resistor to VBB.

A related that part that I am also using. (TPS4H160-Q1) says that the current limit pin should be tied to GND through the resistor.

Are they really different or is one data sheet in error.

Thanks,

Don

    Hello Don,

    The datasheet for both are correct. They are two different generation devices. The TPS4H160-Q1 requires the current limit resistor to be between the current limit pin and ground while the TPS1HB08 requires the current limit resistor to be between the pin and VBB.
