#Goal

- Finalize the MP2650GV-0000-P charger section within the Gay Teal P.K.E. Meter project by selecting and adding an appropriate power inductor as well as completing the sensing/monitoring network for pins PSYS, IAM, IBM, IAP, and IAN. This update will ensure the charger is fully functional and ready for later integration.

#Implementation plan

1. **Review and validate existing charger setup**

1. Confirm that the USB-C input, battery (J1), system output (J2), and all other power nodes (VBUS, BATT, SYS, etc.) are correctly connected.

2. Identify available connection points for the sensor network associated with PSYS, IAM, IBM, IAP, and IAN.

2. **Select and add the power inductor**

1. Define inductor requirements based on the MP2650GV-0000-P charger current specifications including inductance value, current rating, DCR, and package/footprint constraints.

2. Search for a suitable inductor in the Flux parts library that meets these criteria.

3. Place the selected power inductor into the schematic in the appropriate location between the charger power stage and the rest of the circuit.

3. **Complete the sensing/monitoring network**

1. Evaluate the sensor network connections for PSYS, IAM, IBM, IAP, and IAN, ensuring correct routing and placeholder components where necessary.

2. Add any missing components or placeholders (e.g., resistors, filters) to finalize the network circuit.

3. Connect the sensor network signals to their corresponding monitoring pins on the MP2650GV-0000-P.

4. **Document and validate changes**

1. Update the schematic documentation and project description with details of the added inductor and completed sensor network.

2. Verify that the updated charger block now integrates seamlessly with the existing circuit sections and meets preliminary electrical requirements.

#Success criteria

- The power inductor is selected from the Flux parts library, added to the schematic, and meets the specified electrical requirements.

- The sensing/monitoring network for pins PSYS, IAM, IBM, IAP, and IAN is fully connected and documented, with appropriate components or placeholders in place.

- The updated MP2650 charger section integrates properly with the rest of the Gay Teal P.K.E. Meter project and is ready for subsequent integration steps.

He elegido un inductor SMD de 1.5 uH con MPN específico para el bloque del cargador y voy a cerrar la red de sensado según la aplicación recomendada del MP2650: RS1 = 10 mOhm con 2 x 2 ohm y 100 nF para el filtro de IAP/IAN, mientras que PSYS, IAM e IBM quedan expuestos como salidas analógicas de monitorización listas para integración posterior.
