BQ25883RGER

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

BQ25883RGER from Texas Instruments, in a VQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 D- bidirectional Negative USB data line. Used for USB host/charging port detection (BC1.2), including data contact detection (DCD) and secondary detection.
2 STAT output Open drain charge status indicator. Connect to pull-up rail via 10-kΩ resistor. LOW = charge in progress; HIGH = charge complete or disabled; blinks at 1Hz on fault. Can be disabled via STAT_DIS.
3 /CE input Active low charge enable pin. Battery charging is enabled when EN_CHG bit = 1 and /CE pin is LOW. Internally pulled low with 900-kΩ resistor.
4 SDA bidirectional I2C interface data. Connect SDA to the pull-up rail through a 10-kΩ resistor.
5 SCL input I2C interface clock. Connect SCL to the pull-up rail through a 10-kΩ resistor.
6 /INT output Open drain active low interrupt output. Connect to pull-up rail via 10-kΩ resistor. Sends 256-µs active-low pulse to the host to report charger status and fault events.
7 TS input Temperature qualification voltage. Connect a NTC thermistor (recommend 103AT-2). Program temperature window with a resistor divider from REGN to TS to GND; charge suspends when TS is out of range.
8 ILIM input Input current limit (IINDPM) programming. IINDPM loop regulates ILIM pin voltage at 0.8V. Resistor to GND sets IINMAX = KILIM / RILIM. Short to GND for maximum limit; do not float. Cannot set below 500mA.
9 /PG output Open drain active low power good indicator. Connect to pull-up rail via 10-kΩ resistor. LOW indicates a good input source when input voltage is within VVBUS_OP (3.9V) and can provide more than IPOORSRC (30 mA).
10 NC unconnected No connect. Leave floating or tie to ground.
11 REGN power_out Gate drive supply. Bias supply for internal MOSFET drivers and IC. Bypass REGN to GND with a 4.7-µF ceramic capacitor. REGN current limit is 50 mA.
12 BTST power_in PWM high-side driver supply. Internally BTST is connected to the cathode of the boot-strap diode. Connect a 47-nF bootstrap capacitor from SW to BTST.
13 BAT power_in Battery power connection. Connect minimum recommended 10-µF capacitance (after derating) closely to BAT and GND.
14 BAT power_in Battery power connection. Connect minimum recommended 10-µF capacitance (after derating) closely to BAT and GND.
15 SYS power_out System connection. Internal BATFET connects SYS to BAT. When battery falls below minimum system voltage, the switch-mode converter keeps SYS above the minimum. Connect 2x22-µF capacitance (after derating) close to SYS and PGND.
16 SYS power_out System connection. Internal BATFET connects SYS to BAT. When battery falls below minimum system voltage, the switch-mode converter keeps SYS above the minimum. Connect 2x22-µF capacitance (after derating) close to SYS and PGND.
17 SW power_out Inductor connection. Connect to the switched side of the external inductor.
18 SW power_out Inductor connection. Connect to the switched side of the external inductor.
19 GND power_in Ground return.
20 GND power_in Ground return.
21 PMID power_in Blocking MOSFET connection. Total low-ESR capacitance on VBUS and PMID (after derating) is 10 µF; at least 1-µF at VBUS with remainder (typically 10 µF) at PMID.
22 PMID power_in Blocking MOSFET connection. Total low-ESR capacitance on VBUS and PMID (after derating) is 10 µF; at least 1-µF at VBUS with remainder (typically 10 µF) at PMID.
23 VBUS power_in Input supply. VBUS is connected to the external DC supply (3.9-6.2 V operating). Bypass VBUS to GND with at least 1-µF ceramic capacitor placed close to the IC.
24 D+ bidirectional Positive USB data line. Used for USB host/charging port detection (BC1.2), including data contact detection (DCD) and secondary detection.
