TPS3840DL44DBVRQ1

Texas Instruments · Supervisor And Reset ICs · SOT-23-5

TPS3840DL44DBVRQ1 from Texas Instruments, in a SOT-23-5. 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 RESET output Active-low open-drain reset output that is driven low when MR is pulled to a logic low or VDD falls below the negative threshold VIT-, and remains asserted for the delay time tD after MR is floating or above VMR_L and VDD rises above VIT+.
2 VDD power_in Input supply voltage monitored by the device, with a recommended operating range of 1.5 V to 10 V and an absolute maximum of 12 V.
3 GND power_in Ground reference pin.
4 MR input Manual reset input that asserts a reset when pulled to a logic low (VMR_L), may be left floating when not in use, and should not be driven higher than VDD.
5 CT passive Capacitor time delay pin for programming the reset delay tD, from 50 µs with no capacitor up to 6.2 s with a 10 µF capacitor, and left floating for the smallest fixed delay.

  • 3D model files: tps3840dl44dbvrq1-etched.step / tps3840dl44dbvrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps3840dl44dbvrq1.step / tps3840dl44dbvrq1.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (39 pp, sha256 bcbd6b6ff60acd14, retrieved 2026-11-05, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
