BQ24075RGTT

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

BQ24075RGTT 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 for battery pack temperature monitoring; sources 72-78 μA to a 10 kΩ thermistor with cold and hot trip points at 2100 mV and 300 mV respectively.
2 BAT bidirectional Battery charger power stage output and voltage sense input; supports 1.5 A charging current and 4.5 A discharge current; bypass with 4.7-47 μF ceramic capacitor to VSS.
3 BAT bidirectional Battery charger power stage output and voltage sense input; supports 1.5 A charging current and 4.5 A discharge current; bypass with 4.7-47 μF ceramic capacitor to VSS.
4 CE input Charge enable active-low input with internal ~285 kΩ pull-down; connect low to enable charging, high to disable charging while keeping OUT active and battery supplement mode available.
5 EN2 input Input current limit configuration input with internal ~285 kΩ pull-down; with EN1 selects input current mode (100 mA USB100, 500 mA USB500, resistor-programmable, or suspend).
6 EN1 input Input current limit configuration input with internal ~285 kΩ pull-down; with EN2 selects maximum input current mode (100 mA, 500 mA, resistor-programmable 200-1500 mA, or suspend).
7 PGOOD output Open-drain power good status indication output; pulls low when valid input detected (VBAT + VIN(DT) < VIN < VOVP), high impedance otherwise with 1.2 ms deglitch time.
8 VSS power_in Ground reference pin; must be connected to thermal pad and circuit ground at all times serving as voltage reference for all signal levels.
9 CHG output Open-drain charging status indication output; pulls low on first charge cycle, flashes at 2 Hz for timer fault, high impedance when charging complete or charger disabled.
10 OUT power_out System supply regulated output at 5.4-5.6 V with up to 4.5 A continuous current; provides regulated power when input valid or connects to VBAT when input invalid (unless SYSOFF high).
11 OUT power_out System supply regulated output at 5.4-5.6 V with up to 4.5 A continuous current; provides regulated power when input valid or connects to VBAT when input invalid (unless SYSOFF high).
12 ILIM input Adjustable input current limit programming input; connect 1100-8000 Ω resistor to VSS to set maximum input current from 200 mA to 1500 mA per equation IIN-MAX = KILIM/RILIM.
13 IN power_in Input power connection; normal operating range 4.35-6.4 V, tolerates up to 26 V without damage (operation suspended above VOVP), maximum input current 1.5 A; bypass with 1-10 μF capacitor.
14 TMR input Pre-charge and fast-charge safety timer programming input; connect 18-72 kΩ resistor to VSS to program timer duration using equations tPRECHG = KTMR × RTMR and tMAXCHG = 10 × KTMR × RTMR.
15 SYSOFF input System enable input with internal ~5 MΩ pull-up to VBAT; connect high to turn off battery FET and disable charging when adapter connected, low for normal operation.
16 ISET bidirectional Fast-charge current programming input/output; connect 590-8900 Ω resistor to VSS to program charging current up to 1.5 A per equation ICHG = KISET/RISET; outputs 1/400 of charge current for monitoring.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
