Texas Instruments · Battery Management · QFN-16-EP(3x3)
BQ24072TRGTT from Texas Instruments, in a QFN-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 connects to the center tap of a VIN-to-GND resistor divider; for applications not using the TS function, the divider is set to a 20% ratio. |
| 2 | BAT | bidirectional | Charger power stage output and battery voltage sense input that connects to the positive battery terminal and must be bypassed to VSS with a 4.7μF to 47μF ceramic capacitor. |
| 3 | BAT | bidirectional | Charger power stage output and battery voltage sense input that connects to the positive battery terminal and must be bypassed to VSS with a 4.7μF to 47μF ceramic capacitor. |
| 4 | CE | input | Active-low charge enable: a high level places the charger in standby mode and a low level enables charging; CE is internally pulled down with ~285kΩ and must not be left unconnected. |
| 5 | EN2 | input | Input current limit configuration input that works with EN1 to select 100 mA, 500 mA, ILIM-set, or standby input current; internally pulled down with ~285kΩ and must not be left unconnected. |
| 6 | EN1 | input | Input current limit configuration input that works with EN2 to select 100 mA, 500 mA, ILIM-set, or standby input current; internally pulled down with ~285kΩ and must not be left unconnected. |
| 7 | PGOOD | output | Open-drain power-good status output that pulls to VSS when a valid input source is detected and is high-impedance otherwise; use a 1kΩ to 100kΩ pull-up resistor, and PGOOD sink current is limited to 15 mA. |
| 8 | VSS | power_in | Ground that must connect to the thermal pad and the circuit ground rail and must be connected to ground at all times. |
| 9 | CHG | output | Open-drain charge status output that pulls to VSS while charging, is high-impedance when charging is complete or the charger is disabled, and flashes on a timer fault; use a 1kΩ to 100kΩ pull-up resistor. CHG sink current is limited to 15 mA. |
| 10 | OUT | output | System supply output that provides a regulated output when the input is below the OVP threshold and above the regulation voltage, and must be bypassed to VSS with a 4.7μF to 47μF ceramic capacitor. |
| 11 | OUT | output | System supply output that provides a regulated output when the input is below the OVP threshold and above the regulation voltage, and must be bypassed to VSS with a 4.7μF to 47μF ceramic capacitor. |
| 12 | ILIM | output | Adjustable input current limit programming pin that connects to VSS through a 1.07kΩ to 7.5kΩ resistor to set the maximum input current (EN2=1, EN1=0); leaving ILIM unconnected disables all charging. |
| 13 | IN | input | Input power connection for the AC adapter or USB port with an operating range of 4.35V to 6.6V; it accepts up to 26V without damage but operation is suspended above the operating range, and it must be bypassed to VSS with a 1μF to 10μF ceramic capacitor. |
| 14 | TMR | input | Timer programming input for the pre-charge and fast-charge safety timers: connect to VSS to disable all timers, use an 18kΩ to 72kΩ resistor to VSS to set custom lengths, or leave unconnected for default values. |
| 15 | TD | input | Termination disable input: connect high to disable charger termination or to VSS to enable it; TD is checked only during startup, cannot change during operation, and is internally pulled down to VSS with ~285kΩ. |
| 16 | ISET | bidirectional | Fast-charge current programming input that connects to VSS through a 590Ω to 3kΩ resistor; charging is disabled if ISET is left unconnected, and while charging its voltage reflects the actual charge current. |
| 17 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
