Tool/software:
HI team,
Could you help with below several questions on BQ76952:
1. I was using EVM, and find that BQ76952 will automatically wake up after power supplied. And TS2 always show low voltage even I am not pressing the WAKE button on PCB. I use the GUI to send the chip to shutdown mode, then I use the digital multimeter to try measure the TS2 pin voltage when device in shutdown mode. I found that the device will wake up once the DMM is attached on the TS2 pin, which seems really weird to me, as the datasheet clearly says the TS2 pin was internally pull high, and to wake up the device requires the TS2 pin pull low.
Can you help to explain above behavior?
2. How to correctly measure the sleep current consumption of the device using the EVM? I found that device about 270uA in active mode, and 110uA in sleep mode, which is significantly higher than the DS EC spec.
Thanks
