pulled low when valid supply (between VBAT+VSLP and VOVP) connected to USB or IN, high-impedance otherwise. |+| 8 | CHG | tri_state | Charge Status open-drain output; pulled low at charge cycle start and remains low while charging, high-impedance when charging terminates or no supply connected. |+| 9 | TS | input | Battery NTC thermistor monitor input; connect to center tap of resistor divider from DRV to GND with thermistor to GND providing Hot/Cold temperature shutdown thresholds. |+| 10 | BGATE | output | External P-Channel MOSFET gate driver output connected to external FET gate for low-resistance battery discharge path; low during high-impedance mode and when no input connected. |+| 11 | BAT | bidirectional | Battery positive terminal connection; bypass to GND with minimum 1μF capacitor to support high current transients and minimize parasitic inductance. |+| 12 | BAT | bidirectional | Battery positive terminal connection; bypass to GND with minimum 1μF capacitor to support high current transients and minimize parasitic inductance. |+| 13 | SYS | input | System voltage sense connected to output bulk capacitors; bypass locally with minimum 10μF (47μF recommended for best transient response). |+| 14 | SYS | input | System voltage sense connected to output bulk capacitors;

not current limited so short-circuit protection required. |+| 21 | IN | power_in | AC Adapter or alternate power supply input rated for 20V with overvoltage protection; bypass to PGND with minimum 1μF ceramic capacitor; 0-2.5A maximum input current. |+| 22 | USB | power_in | USB input power supply rated for 6.5V with overvoltage protection; bypass to PGND with minimum 1μF ceramic capacitor; 0-1.5A maximum input current. |+| 23 | PMIDU | output | USB input path node connecting reverse blocking and high-side MOSFETs;
