BQ25895EVM-664: Question about INT.

Part Number: BQ25895EVM-664


I am testing the BQ25895EVM .


 In datasheet, pulse occurs when INT pin is below. However, there is no change when measured by EVM

   How is the INT (TP15) of the EVM measured?


The INT notifies the system on the device operation. The following events will generate 256-µs INT pulse.

• USB/adapter source identified (through PSEL or DPDM detection, with OTG pin)

• Good input source detected – VBUS above battery (not in sleep) – VBUS below VACOV threshold – VBUS above VVBUSMIN (typical 3.8 V) when IBADSRC (typical 30 mA) current is applied (not a poor source)

• Input removed • Charge Complete • Any FAULT event in REG0C


  • Hi David, 

    Below is a waveform capture of INT pin using BQ25895EVM. On my EVM I do not observe any issues with INT functionality. This specific capture is observed with Vbat = 3.9V then plugging in 5V input. 

    Best Regards,
