Texas Instruments · Battery Management · VQFN-24-EP(4x4)

BQ24192RGER 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; place 1-µF ceramic capacitor close to IC from VBUS to PGND.
2 PSEL input Power source selection input; High indicates USB host source, Low indicates adapter source.
3 PG output Open-drain active-low 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 indicates charge in progress, HIGH indicates charge complete or disabled.
5 SCL input I2C interface clock; connect through 10-kΩ pull-up resistor to logic rail.
6 SDA bidirectional I2C interface data line; connect through 10-kΩ pull-up resistor to logic rail.
7 INT output Open-drain interrupt output; sends active-low 256-µs pulse to host to report charger status and faults.
8 OTG input USB current limit selection during buck mode; High sets IIN to 500 mA or enables boost mode, Low sets IIN to 100 mA.
9 CE input Active-low charge enable; battery charging enabled when REG01[5:4] = 01 and CE is Low.
10 ILIM input Input current limit setting; connect resistor to ground to set maximum limit as IINMAX = (1V/RILIM) × 530 with minimum 500 mA.
11 TS1 input Temperature sensor input 1; connect negative temperature coefficient thermistor with resistor divider from REGN to TS1 to ground.
12 TS2 input Temperature sensor input 2; connect negative temperature coefficient thermistor with resistor divider from REGN to TS2 to ground.
13 BAT power_in Battery positive connection point; internal BATFET connected between BAT and SYS; connect 10-µF capacitor closely to pin.
14 BAT power_in Battery positive connection point; internal BATFET connected between BAT and SYS; connect 10-µF capacitor closely to pin.
15 SYS power_out System output connection point; converter maintains SYS above minimum system voltage setting when battery falls below minimum.
16 SYS power_out System output connection point; converter maintains SYS above minimum system voltage setting when battery falls below minimum.
17 PGND power_in Power ground connection for high-current power converter; connect directly to ground of input and output capacitors.
18 PGND power_in Power ground connection for high-current power converter; connect directly to ground of input and output capacitors.
19 SW output Switching node connecting to output inductor; connect 0.047-µF bootstrap capacitor from SW to BTST.
20 SW output Switching node connecting to output inductor; connect 0.047-µF bootstrap capacitor from SW to BTST.
21 BTST power_in PWM high-side driver positive supply; internally connected to boost-strap diode anode; connect 0.047-µF bootstrap capacitor from SW.
22 REGN power_out PWM low-side driver positive supply output; connect 4.7-µF (10V rating) ceramic capacitor from REGN to analog ground close to IC.
23 PMID output Internal node connected to drain of reverse blocking MOSFET and drain of high-side FET; place 1-µF capacitor on VBUS to PGND and remaining on PMID to PGND.
24 VBUS power_in Charger input voltage; place 1-µF ceramic capacitor close to IC from VBUS to PGND.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
