BQ24075TRGTR

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

BQ24075TRGTR 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 connected to battery pack temperature monitoring resistor divider from VIN to GND.
2 BAT power_in Charger power stage output and battery voltage sense input connected to positive terminal of battery; bypass to VSS with 4.7μF to 47μF ceramic capacitor.
3 BAT power_in Charger power stage output and battery voltage sense input connected to positive terminal of battery; bypass to VSS with 4.7μF to 47μF ceramic capacitor.
4 CE input Charge enable active-low input with ~285kΩ internal pull-down; connect high to disable charging or low to enable charging.
5 EN2 input Input current limit configuration input with ~285kΩ internal pull-down; use EN1 and EN2 to control maximum input current and USB compliance modes per Table 1.
6 EN1 input Input current limit configuration input with ~285kΩ internal pull-down; use EN1 and EN2 to control maximum input current and USB compliance modes per Table 1.
7 PGOOD tri_state Open-drain power good status indication output; pulls to VSS when valid input source detected (VBAT + VIN-DT < VIN < VOVP).
8 VSS power_in Ground connection to thermal pad and printed circuit board ground rail.
9 CHG tri_state Open-drain charging status indication output; pulls to VSS when battery is charging, flashes at 2Hz to indicate timer fault.
10 OUT power_out System supply output regulated to 5.5V; bypass to VSS with 4.7μF to 47μF ceramic capacitor.
11 OUT power_out System supply output regulated to 5.5V; bypass to VSS with 4.7μF to 47μF ceramic capacitor.
12 ILIM input Adjustable current limit programming input; connect 1.07kΩ to 7.5kΩ resistor from ILIM to VSS to program maximum input current 200mA to 1.5A (EN2=1, EN1=0).
13 IN power_in Input power connection from AC adapter or USB port with 4.35V to 6.6V operating range; bypass to VSS with 1μF to 10μF ceramic capacitor.
14 TMR input Timer programming input; connect 18kΩ to 72kΩ resistor between TMR and VSS to program pre-charge and fast-charge safety timer duration.
15 SYSOFF input System enable input with ~5MΩ internal pull-up to VBAT; connect high to disconnect battery from system output and disable charging.
16 ISET input Fast charge current programming input; connect 590Ω to 3kΩ resistor from ISET to VSS to program fast charge current level, voltage reflects actual charge current during operation.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
