BQ25504RGTT

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

BQ25504RGTT from Texas Instruments, in a VQFN-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 VSS power_in General ground connection for the device with connection to thermal pad.
2 VIN_DC power_in DC voltage input from energy harvesters (minimum 130 mV to 3 V) requiring minimum 4.7 µF input capacitor to pin 1.
3 VOC_SAMP input MPPT sampling pin connected to resistor divider mid-point between VIN_DC and GND for setting MPP threshold, or connect to VSTOR to disable MPPT.
4 VREF_SAMP input Reference voltage storage pin with 0.01 µF low leakage capacitor to GND, or tied to GND to disable input voltage regulation from low impedance sources.
5 OT_PROG input Overtemperature threshold programming input: connect to GND for 60°C limit or to VSTOR for 120°C limit.
6 VBAT_OV input Overvoltage threshold programming input at mid-point of resistor divider between VRDIV and GND.
7 VRDIV output Resistor divider biasing voltage output.
8 VBAT_UV input Undervoltage threshold programming input at mid-point of resistor divider between VRDIV and GND opening PFET between VBAT and VSTOR when voltage falls below threshold.
9 OK_HYST input VBAT_OK hysteresis threshold programming input at resistor divider mid-point between VRDIV and GND, or connect to GND if not used.
10 OK_PROG input VBAT_OK threshold programming input at resistor divider mid-point between VRDIV and GND, or connect to GND if not used.
11 VBAT_OK output Digital battery good indicator output internally referenced to VSTOR voltage; leave floating if not used.
12 AVSS power_in Analog supply ground connection for the device with connection to thermal pad.
13 VSS power_in General ground connection for the device with connection to thermal pad.
14 VBAT power_in Rechargeable battery or storage element connection requiring minimum 100 µF equivalent capacitance.
15 VSTOR power_out Boost charger output for system load requiring minimum 4.7 µF bulk capacitor plus 0.1 µF bypass capacitor between this pin and VSS (pin 1).
16 LBST passive Inductor node for boost charger switching network with 22 µH inductor connected between this pin and pin 2 (VIN_DC).
17 PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
