| | Min | Typ | Max | Unit | |---|---|---|---|---| | Voltage (DC) | 3.135 | 3.300 | 3.465 | V | | Ripple (p-p) | - | 15 | 50 | mV | | Impedance to GND | 1k | 4.7k | 10k | Ω |

If you search for "BG2-U01" specifically, you won't find a single component you can buy on DigiKey. That’s because it isn’t a component; it’s a . bg2-u01 test point

| | Value | | --- | --- | | Test Point ID | BG2-U01 | | Board Revision | 2.0 | | Circuit Zone | Power Regulation / Battery Gate 2 | | Test Type | DC Voltage & Signal Integrity | | Pass/Fail Criteria | 3.3V ±5% (3.135V – 3.465V) | | | Min | Typ | Max |

| | Likely Cause | Next Step | |---|---|---| | 0V | No power to BG2 regulator | Check FET Q2 gate enable | | ~1.2V | Short to adjacent signal line | Visual inspect for solder bridge | | >4V | Regulator failed closed | Replace U5 (BG2 controller) | | Oscillating/noisy | Missing decoupling cap (C117) | Re-solder or replace C117 | Drop a comment below with the model number,
