    BMA253 INT1/INT2 Output Characteristics

    BMA253 INT1/INT2 Output Characteristics

    Hello,

    Can you please tell me the INT1/INT2 Output Characteristics of BMA253?

    I looked through the datasheet but could not find the information in the datasheet.

    How much does the INT1/INT2 Output pin sink current when the output is set to Low '0'.

     

    I have the below situation:

    BMA253 is communicating with a master device by I2C.

    I2C bus is connected and pulled-up by 10kohm.

    BMA253 INT1 is connected to the master device GPIO and the Input pin is pulled-up internally with 25kohm resistor. (By mistake I have set the pin to Input pull-up)

    BMA253 INT2 is connected to the master device GPIO and the Input pin is pulled-down internally with 25kohm resistor.

    BMA253 INT1 and INT2 is active '1' 

    So normally when the interrupt doesn't occur the INT1/INT2 output is set to Low '0'.

     

    Thank you.

    Hello Coleman,

    Which function do you map to INT1?

    Hello BSTRobin,

    I map the orient detection and low-g detection to INT1.
