BQ25300RTER

Texas Instruments · Battery Management · QFN-16-EP(3x3)

BQ25300RTER 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 VBUS power_in Charger input voltage in range 4.1V to 17V; reverse blocking MOSFET source connects here.
2 REGN power_out Low-side FET driver positive supply output from internal 5V LDO.
3 STAT tri_state Charge status indication open-drain output; pulled LOW during charging, open on completion, blinks at 1Hz for faults.
4 ICHG input Charge current program input; set charging current via ICHG = KICHG (40000) / RICHG; charging disabled if open or shorted to GND.
5 POL input EN pin polarity selection input; determines enable/disable logic for EN pin.
6 EN input Device enable/disable input; controls device power-up and charging based on POL pin setting.
7 TS input Battery temperature voltage input from NTC thermistor; charge suspends when temperature outside 0°C to 45°C window.
8 NC unconnected No connection; keep pin floating or grounded.
9 VSET input Charge voltage setting input; set final battery regulation voltage to 3.6V, 4.05V, 4.15V, or 4.2V via resistor divider.
10 BAT input Battery voltage sensing input; connect to battery positive terminal and inductor output node for voltage regulation feedback.
11 GND power_in Ground reference connected to thermal pad; single point connection recommended between power and analog ground.
12 GND power_in Ground reference connected to thermal pad; single point connection recommended between power and analog ground.
13 SW tri_state Switching node connected to output inductor; internally connected to source of high-side MOSFET and drain of low-side MOSFET.
14 SW tri_state Switching node connected to output inductor; internally connected to source of high-side MOSFET and drain of low-side MOSFET.
15 BTST power_out High-side FET driver bootstrap supply connected to bootstrap diode cathode; provides isolated gate drive voltage for high-side MOSFET.
16 PMID tri_state Power intermediate node connected to drain of reverse blocking MOSFET and drain of high-side MOSFET; actively switches between input and converter voltages.
17 Thermal Pad power_in Ground reference and thermal pad for die heat dissipation; must be soldered to PCB ground plane with vias for thermal conduction.
