TPS2042BDRBR

Texas Instruments · Power Distribution Switches · SON-8-EP(3x3)

TPS2042BDRBR from Texas Instruments, in a SON-8-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 GND power_in Ground connection; reference potential for all pins.
2 IN input Input supply voltage; operating range 2.7V to 5.5V.
3 EN1 input Active-low enable input for OUT1 power switch; logic low activates the switch.
4 EN2 input Active-low enable input for OUT2 power switch; logic low activates the switch.
5 OC2 output Open-drain overcurrent detection output for OUT2; active-low, pulls down on overcurrent condition.
6 OUT2 output Power switch output 2; rated for 500mA continuous current with 70mΩ ON-resistance.
7 OUT1 output Power switch output 1; rated for 500mA continuous current with 70mΩ ON-resistance.
8 OC1 output Open-drain overcurrent detection output for OUT1; active-low, pulls down on overcurrent condition.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS2042BDRBR
  • Footprint: Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm
  • 3D model: SON-8-EP(3x3) (KiCad packages3D, STEP)
  • 3D model files: tps2042bdrbr-etched.step / tps2042bdrbr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps2042bdrbr.step / tps2042bdrbr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
