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). |
