BQ24074RGTT

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

BQ24074RGTT from Texas Instruments, in a VQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TS input External NTC Thermistor Input; connect to the NTC thermistor in battery pack to monitor 10kΩ thermistor.
2 BAT bidirectional Charger Power Stage Output and Battery Voltage Sense Input; connect to positive terminal of battery and bypass to VSS with 4.7-μF to 47-μF ceramic capacitor.
3 BAT bidirectional Charger Power Stage Output and Battery Voltage Sense Input; connect to positive terminal of battery and bypass to VSS with 4.7-μF to 47-μF ceramic capacitor.
4 CE input Charge Enable Active-Low Input; connect high to disable battery charging with OUT remaining active, connect low to enable charger, internally pulled down with ≈285 kΩ.
5 EN2 input Input Current Limit Configuration Input; use EN1 and EN2 to control maximum input current and enable USB compliance, internally pulled down with ≈285 kΩ.
6 EN1 input Input Current Limit Configuration Input; use EN1 and EN2 to control maximum input current and enable USB compliance, internally pulled down with ≈285 kΩ.
7 PGOOD output Open-drain Power Good Status Indication Output; pulls to VSS when valid input source is detected, high-impedance when input power outside specified limits.
8 VSS power_in Ground; connect to thermal pad and ground rail of circuit with internal electrical connection to exposed thermal pad.
9 CHG output Open-Drain Charging Status Indication Output; pulls to VSS when battery is charging, high-impedance when charging complete or charger disabled.
10 OUT output System Supply Output; provides regulated output when input is below OVP threshold and above regulation voltage, bypass to VSS with 4.7-μF to 47-μF capacitor.
11 OUT output System Supply Output; provides regulated output when input is below OVP threshold and above regulation voltage, bypass to VSS with 4.7-μF to 47-μF capacitor.
12 ILIM input Adjustable Current Limit Programming Input; connect 1100-Ω to 8-kΩ resistor from ILIM to VSS to program maximum input current (EN2=1, EN1=0), leaving unconnected disables charging.
13 IN input Input Power Connection; connect to external DC supply with input operating range 4.35 V to 10.5 V for BQ24074, bypass with 1 μF to 10 μF capacitor to VSS.
14 TMR input Timer Programming Input; controls pre-charge and fast-charge safety timers, connect to VSS to disable or 18-kΩ to 72-kΩ resistor to program desired length.
15 ITERM input Termination Current Programming Input; connect 0-Ω to 15-kΩ resistor from ITERM to VSS to program termination current, leave unconnected for default 10% termination threshold.
16 ISET bidirectional Fast Charge Current Programming Input; connect 590-Ω to 8.9-kΩ resistor from ISET to VSS to program fast charge current level, voltage at ISET reflects actual charging current.
17 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).
