Other Parts Discussed in Thread: TPS62743,
Hi Team,
Our customer is currently evaluating the TPS62743 through its EVM. Input stage is a Li-polymer battery with short circuit protection. Output voltage is configured 3V as per JP3,JP4 and JP5. However upon disabling the device through JP1 the battery protection circuit trips. They've tried other li-polymer battery manufacturers but encountered the same results. The datasheet does not provide further information about the output discharge of the device.
Is this a normal behavior of the TPS62743 pulling the device to ground (EN low) causing the input short? Or is there a possibility there is an issue with the TPS62743EVM-689 used by our customer?
Thanks in advance!
Kind Regards,
Jejomar
