BQ24193RGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 | VBUS | power_in | Charger input voltage with operating range 3.9V to 17V; internal reverse blocking MOSFET connected between VBUS and PMID. |
| 2 | PSEL | input | Digital power source selection input; High for USB host source, Low for adapter source. |
| 3 | PG | output | Open-drain power good indicator; LOW when input voltage between UVLO and ACOV above SLEEP threshold and current limit above 30 mA. |
| 4 | STAT | output | Open-drain charge status output; LOW for charging in progress, HIGH for complete or disabled, blinking at 1 Hz on fault. |
| 5 | SCL | input | I²C interface clock input. |
| 6 | SDA | bidirectional | I²C interface data bidirectional pin. |
| 7 | INT | output | Open-drain interrupt output; sends active low 256-µs pulse to host to report charger status and fault conditions. |
| 8 | OTG | input | USB current limit selection for buck mode (500 mA when High, 100 mA when Low) and boost mode enable when REG01[5:4]=10. |
| 9 | CE | input | Active-low charge enable input; battery charging enabled when REG01[5:4]=01 and CE Low. |
| 10 | ILIM | input | Analog input pin sets maximum input current limit via resistor to ground; minimum 500 mA programmed on pin. |
| 11 | TS1 | input | Analog temperature sensor input #1 for NTC thermistor; charge suspends when out of range, must be connected with TS2. |
| 12 | TS2 | input | Analog temperature sensor input #2 for NTC thermistor; charge suspends when out of range, must be connected with TS1. |
| 13 | BAT | power_in | Positive battery terminal connection to internal BATFET switch between BAT and SYS. |
| 14 | BAT | power_in | Positive battery terminal connection to internal BATFET switch between BAT and SYS. |
| 15 | SYS | power_out | System power output node; switch-mode converter maintains SYS above minimum system voltage when battery falls below threshold. |
| 16 | SYS | power_out | System power output node; switch-mode converter maintains SYS above minimum system voltage when battery falls below threshold. |
| 17 | PGND | power_in | Power ground for high-current converter sections; internally connected to n-channel LSFET source. |
| 18 | PGND | power_in | Power ground for high-current converter sections; internally connected to n-channel LSFET source. |
| 19 | SW | output | Analog switching node connected to output inductor; connects HSFET source and LSFET drain internally. |
| 20 | SW | output | Analog switching node connected to output inductor; connects HSFET source and LSFET drain internally. |
| 21 | BTST | power_out | Bootstrap supply for PWM high-side gate driver; internally connected to bootstrap diode anode. |
| 22 | REGN | power_out | PWM low-side driver positive supply output connected to bootstrap diode cathode; also bias rail for TS1 and TS2. |
| 23 | PMID | output | Analog intermediate power node connected to reverse blocking MOSFET drain and HSFET drain. |
| 24 | VBUS | power_in | Charger input voltage with operating range 3.9V to 17V; internal reverse blocking MOSFET connected between VBUS and PMID. |
| 25 | PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
