TMP422-Q1: TMP422-Q1: TMP451-Q1 V+, DX1~DX4 rating current (Limited current) (max) is ?

Part Number: TMP422-Q1
Other Parts Discussed in Thread: TMP451-Q1,

What is the maximum rating current ((limited current) of TPM451-Q1 PIN1(V+,) PIN1~3(DX1~DX4)?

  • Hi Chen,

    The max current for the input pins of TMP422-Q1 and TMP451-Q1 can be found in the datasheet as seen below.

    TMP422-Q1:

    TMP451-Q1:

    The input pins are any pins that are expected to sink current such as D+ and D-, ALERT, THERM, SCL, and SDA. As for V+, this is a supply pin so what we characterize in this case is the consumption of the device as it is not expected that you would sink current from a stable current source into power the device--otherwise, if you are interested in ESD ratings, these can also be found in the datasheet. For average IQ of the device over power supply, you can refer to the IQ (power supply) specs and graphs in the datasheet.

    Best regards,
