TPS25820DSSR

Texas Instruments · USB Converters · WSON-12-EP(2x3)

TPS25820DSSR from Texas Instruments, in a WSON-12-EP(2x3). 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 IN power_in Device input supply for the VBUS internal power switch, and for the VCONN switch on the TPS25820; the recommended supply range is 4.5 V to 5.5 V.
2 IN power_in Device input supply for the VBUS internal power switch, and for the VCONN switch on the TPS25820; the recommended supply range is 4.5 V to 5.5 V.
3 CHG input Charge logic input that selects between standard USB and 1.5-A Type-C current sourcing ability; the input range is 0 to 5.5 V, with VIH of at least 2 V and VIL of at most 0.8 V.
4 EN input Logic input that turns the device on and off; the input range is 0 to 5.5 V, with VIH of at least 2 V and VIL of at most 0.8 V.
5 FAULT output Open-drain logic output that asserts during overtemperature and/or VBUS current-limit conditions; the pull-up voltage is 0 to 5.5 V and the sink current is limited to 10 mA.
6 SINK output Open-drain logic output that asserts when a Type-C Sink is identified on the CC lines; the pull-up voltage is 0 to 5.5 V and the positive sink current is limited to 5 mA (100 ms moving average).
7 POL output Open-drain logic output that asserts when the CC2 pin is connected to the cable CC line, giving the information needed to mux the SuperSpeed lines; the pull-up voltage is 0 to 5.5 V and the positive sink current is limited to 5 mA (100 ms moving average).
8 REF input Analog input for the current reference; connect a 0.5%, 100-ppm, 100-kΩ resistor between this pin and GND.
9 CC1 bidirectional Analog input/output that connects to the Type-C receptacle CC1 pin; absolute maximum pin voltage is 6 V, and the TPS25820 can source up to 250 mA on CC1 or CC2 when supplying VCONN.
10 GND power_in Ground reference for the device; all voltages are specified with respect to this pin.
11 CC2 bidirectional Analog input/output that connects to the Type-C receptacle CC2 pin; absolute maximum pin voltage is 6 V, and the TPS25820 can source up to 250 mA on CC1 or CC2 when supplying VCONN.
12 OUT power_out VBUS power switch output rated for a positive source current of 1.5 A, with an absolute maximum sink current of 2.5 A while applying VBUS.
13 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS25820DSSR
  • Footprint: Package_SON:WSON-12-1EP_3x2mm_P0.5mm_EP1x2.65
  • 3D model: WSON-12-EP(2x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.75 mm nominal WSON height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tps25820dssr-etched.step / tps25820dssr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps25820dssr.step / tps25820dssr.glb are the bare package body.
