TX5817 from XDS, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node of low-side power stage with 100 mΩ ON resistance, driven at 1.1 MHz switching frequency. |
| 2 | VIN | power_in | Power input pin rated 4.7 to 26 V absolute maximum with 11 V over-voltage protection threshold. |
| 3 | VLDO | power_out | Internal linear regulator output providing 4.9 V typical to power internal circuits and external LED indicator. |
| 4 | LED | output | Charging status indicator output for external LED to VLDO; illuminates during charging and extinguishes when charging complete. |
| 5 | NTC | input | Battery temperature detection input via external NTC thermistor; over-temperature shutdown at 150 °C with 20 °C hysteresis. |
| 6 | ISET | output | Charging current setting reference output with 1.19 V reference; external resistor RSET to ground sets charging current level. |
| 7 | BATT | power_out | Battery positive terminal output; charging termination voltage 8.4 V, recharge threshold 8.2 V, trickle charge threshold 5.8 V. |
| 8 | VSYS | power_out | System power output to dual-cell lithium battery from boost converter stage. |
| 9 | PGND | power_in | Power ground pin serving as signal reference and thermal dissipation pad. |
