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

BQ24232HRGTR 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 that monitors a 10-kΩ NTC in the battery pack; for applications without TS use, connect a 10-kΩ fixed resistor from TS to VSS.
2 BAT bidirectional Charger power stage output and battery voltage sense input; connect to the positive battery terminal and bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor.
3 BAT bidirectional Charger power stage output and battery voltage sense input; connect to the positive battery terminal and bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor.
4 CE input Active-low charge enable; a high level places the charger in standby, a low level enables charging, and CE is internally pulled down with about 285 kΩ and must not be left unconnected.
5 EN2 input Input current limit configuration input that sets the maximum input current and enables USB compliance together with EN1; internally pulled down with about 285 kΩ and must not be left unconnected.
6 EN1 input Input current limit configuration input that sets the maximum input current and enables USB compliance together with EN2; internally pulled down with about 285 kΩ and must not be left unconnected.
7 PGOOD output Open-drain power good output that pulls to VSS when a valid input source is detected; connect through a 1-kΩ to 100-kΩ resistor to the logic rail or use with an LED.
8 VSS power_in Ground connection that must be tied to the thermal pad and to the circuit ground rail.
9 CHG output Open-drain charging status output that pulls to VSS while charging and is high impedance when charging is complete or the charger is disabled.
10 OUT output System supply output that regulates when the input is within range and connects to VBAT when the input is out of range; bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor.
11 OUT output System supply output that regulates when the input is within range and connects to VBAT when the input is out of range; bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor.
12 ILIM input Adjustable input current limit programming input; connect a 3.1-kΩ to 7.8-kΩ resistor from ILIM to VSS to set the maximum input current in EN2=1, EN1=0 mode.
13 IN power_in Input power connection to the DC supply (AC adapter or USB); the '232H operating range is 4.35 V to 10.2 V, the input accepts up to 26 V without damage but operation is suspended, and a 1-μF to 10-μF bypass capacitor to VSS is required.
14 TMR input Timer programming input; connect an 18-kΩ to 72-kΩ resistor from TMR to VSS to set the safety timers, connect to VSS to disable them, or leave unconnected for the 5-hour fast-charge and 30-minute precharge defaults.
15 ITERM input Termination current programming input; connect a 0-Ω to 15-kΩ resistor from ITERM to VSS to set the termination current, or leave unconnected for the internal 10% default threshold.
16 ISET bidirectional Fast-charge current programming input; connect a 1.74-kΩ to 34.8-kΩ resistor from ISET to VSS, since charging is disabled if ISET is left unconnected, and the voltage at ISET reflects the charge current.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
