TPS3305-25DR

Texas Instruments · Supervisor And Reset ICs · SOIC-8

TPS3305-25DR from Texas Instruments, in a SOIC-8. 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 SENSE1 input Sense voltage input 1 is monitored against a threshold of 2.93 V typ for the TPS3305-25 (3.3 V nominal), and RESET asserts when it falls below VIT-.
2 SENSE2 input Sense voltage input 2 is monitored against a threshold of 2.25 V typ for the TPS3305-25 (2.5 V nominal), and RESET asserts when it falls below VIT-.
3 WDI input Watchdog timer input must be toggled within 1.6 s typ (1.1 s min, 2.3 s max) or RESET is asserted.
4 GND power_in Ground reference for all voltages; all absolute maximum voltage values are specified with respect to GND.
5 RESET output Active-low reset output that is asserted when either SENSEn input is below its threshold or when WDI is not toggled in time, and held low for the 200 ms typ delay after recovery.
6 RESET output Active-high reset output that is the complement of RESET and is driven high while reset is asserted.
7 MR input Manual reset input that asserts RESET when driven low; logic high threshold is 0.7 x VDD and logic low threshold is 0.3 x VDD.
8 VDD power_in Supply voltage input with a range of 2.7 V to 6 V and maximum supply current of 40 µA.

  • Symbol: TPS3305-25DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tps3305-25dr-etched.step / tps3305-25dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps3305-25dr.step / tps3305-25dr.glb are the bare package body.

Provenance

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