Texas Instruments · Battery Management · QFN-16-EP(3x3)

BQ24075RGTR from Texas Instruments, in a QFN-16-EP(3x3). 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 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).
