Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TS | input | External NTC Thermistor Input connected to 10 kΩ NTC thermistor in battery pack for battery temperature monitoring during charging. |
| 2 | BAT | bidirectional | Charger Power Stage Output and Battery Voltage Sense Input; connect positive terminal of battery with 4.7-μF to 47-μF ceramic bypass capacitor to VSS. |
| 3 | BAT | bidirectional | Charger Power Stage Output and Battery Voltage Sense Input; connect positive terminal of battery with 4.7-μF to 47-μF ceramic bypass capacitor to VSS. |
| 4 | CE | input | Charge Enable Active-Low Input internally pulled down approximately 285 kΩ; high disables charging, low enables charging. |
| 5 | EN2 | input | Input Current Limit Configuration Input internally pulled down approximately 285 kΩ; used with EN1 to control maximum input current per Table 7-2. |
| 6 | EN1 | input | Input Current Limit Configuration Input internally pulled down approximately 285 kΩ; used with EN2 to control maximum input current per Table 7-2. |
| 7 | PGOOD | tri_state | Open-Drain Power Good Status Indication Output; pulls to VSS when valid input source detected, high-impedance when input power outside specified limits. |
| 8 | VSS | power_in | Ground connected to thermal pad and circuit ground; internal electrical connection between exposed thermal pad and VSS pin. |
| 9 | CHG | tri_state | Open-Drain Charging Status Indication Output; pulls to VSS when battery charging, high-impedance when charging complete or charger disabled. |
| 10 | OUT | power_out | System Supply Output providing regulated output when input below overvoltage protection threshold; bypass to VSS with 4.7-μF to 47-μF ceramic capacitor. |
| 11 | OUT | power_out | System Supply Output providing regulated output when input below overvoltage protection threshold; bypass to VSS with 4.7-μF to 47-μF ceramic capacitor. |
| 12 | ILIM | input | Adjustable Current Limit Programming Input; connect 1100-Ω to 8000-Ω resistor from ILIM to VSS to program maximum input current limit. |
| 13 | IN | power_in | Input Power Connection accepting 4.35-V to 6.4-V DC supply from USB or AC adapter; bypass with 1-μF to 10-μF capacitor to VSS. |
| 14 | TMR | input | Timer Programming Input controlling pre-charge and fast-charge safety timers; connect 18-kΩ to 72-kΩ resistor to VSS to program timer duration. |
| 15 | SYSOFF | input | System Enable Input; connect high to turn off FET connecting battery to system output, internally pulled to VBAT through approximately 5 MΩ resistor. |
| 16 | ISET | bidirectional | Fast Charge Current Programming Input; connect 590-Ω to 8900-Ω resistor to VSS to program fast charge current; voltage reflects actual charging current for monitoring. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
