3.4 Power-On Trouble
●
Power-On Sequence
- Connecting Battery
- Power-On Key Detection
- PWON signal goes to ABB and then ABB resets DBB by ONNOFF signal
- ONNOFF turns low(0V) to High(2.8V) and it resets DBB(Calypso)
- All LDOs(internal LDOs of ABB and external LDOs) are turned on
●
Check Points
- Battery Voltage
- Power-On Key Detection(PWON signal)
- Output of LDOs
●
Trouble Shooting Setup
- Connect PIF-UNION Jig to the phone
- Set the TI-Remote switch at PIF-UNION Jig off
●
Trouble Shooting Procedure
- Check Battery Voltage
- END Key Dome switch condition
- Check the output voltage of all LDOs
