BQ24232RGTT

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

BQ24232RGTT 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; monitors 10 kΩ NTC thermistor for battery pack temperature sensing.
2 BAT bidirectional Charger power stage output and battery voltage sense input; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor.
3 BAT bidirectional Charger power stage output and battery voltage sense input; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor.
4 CE input Charge enable active-low input; internally pulled down ~285 kΩ; high disables charging, low enables charger.
5 EN2 input Input current limit configuration input; used with EN1 to control maximum input current and USB compliance; internally pulled down ~285 kΩ.
6 EN1 input Input current limit configuration input; used with EN2 to control maximum input current and USB compliance; internally pulled down ~285 kΩ.
7 PGOOD output Open-drain power good status indication output; pulls to VSS when valid input source detected, high-impedance otherwise.
8 VSS power_in Ground; connect to thermal pad and to the ground rail of the circuit.
9 CHG output Open-drain charging status indication output; pulls to VSS when battery is charging, high impedance when complete or disabled.
10 OUT output System supply output; provides regulated output when input is below OVP threshold; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor.
11 OUT output System supply output; provides regulated output when input is below OVP threshold; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor.
12 ILIM input Adjustable current limit programming input; connect 3.1 kΩ to 7.8 kΩ resistor to VSS to program maximum input current when EN2=1, EN1=0.
13 IN input Input power connection; operating range 4.35 V to 6.6 V; accepts up to 26 V without damage; use 1 μF to 10 μF bypass capacitor to VSS.
14 TMR input Timer programming input; controls precharge and fast-charge safety timers; connect 18 kΩ to 72 kΩ resistor to VSS for desired timer length.
15 ITERM input Termination current programming input; connect 0 Ω to 15 kΩ resistor to VSS to program user-programmable termination current threshold.
16 ISET bidirectional Fast-charge current programming input and charge current output; connect 1.8 kΩ to 36 kΩ resistor to VSS to program fast-charge current.
17 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).
