Audit complete. The existing Datasheet URL is already the official TI document, so no update was required: https://www.ti.com/lit/gpn/TLV840
Verified
  • MPN: TLV840MADL29DBVR
  • Manufacturer: Texas Instruments
  • Package/pins: DBV, SOT-23-5, 5 pins
  • Variant: 2.9 V threshold, open-drain active-low RESET, manual reset, adjustable CT delay
  • Supply: 0.7–6 V
  • Supply current: 120 nA typical
  • Temperature: –40°C to +125°C
  • Default reset delay: 40 µs typical; externally programmable through CT
  • Pin mapping is correct: 1 RESET, 2 VDD, 3 GND, 4 MR, 5 CT
Flagged issues
  • All schematic terminal Pin Type properties are Unspecified; RESET should be Output, VDD/MR Input, GND power/ground, and CT passive/timing.
  • Pin descriptions, functional groups, sections, orientations, and ordering metadata are missing.
  • Part Type is blank.
  • Footprint body and 0.95 mm pitch match DBV, but its pads are 1.2 × 0.6 mm with a 2.5 mm row-center span; TI’s current land-pattern example specifies 1.1 × 0.6 mm pads and 2.6 mm span. This is a small deviation that should be reviewed before publishing.

Update the pin types, descriptions, groups, sections, orientations, and terminal ordering from the datasheet.

flux

I’ll apply datasheet-backed pin metadata to all five terminals, organize the parametric symbol consistently, and verify the resulting properties.

flux

Updated and verified all five pins with datasheet-backed:
  • Electrical pin types, including open-drain RESET
  • Functional descriptions
  • Broad pin groups with matching sections
  • Symbol orientations
  • Deterministic terminal ordering: VDD first (1), GND last (10)
All pin numbers and footprint mappings remain unchanged.
