Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll audit the TPS3828-33DBVR part data, locate/update the official datasheet if needed, then compare symbol pins, footprint/pad count, and pin descriptions against the datasheet. I’ll put the detailed findings in a project file and give you a concise mismatch summary.

Audit complete. I set the project’s Datasheet URL to the official TI HTTPS datasheet and created TPS3828-33DBVR Part Audit with the detailed cross-check.
Summary: symbol pin numbers and footprint pad count match the TPS3828-33DBVR SOT-23-5 datasheet. Flagged issues are mostly metadata: terminal pin types/descriptions are still generic/unspecified, and the project description’s “0 5.8 V” wording conflicts with the datasheet recommended VDD range of 1.1–5.5 V; absolute max VDD is 6 V.

Footprint Cross-Check
  • Project footprint has 5 SMD pads numbered 1 through 5.
  • Pad coordinates match an SOT-23-5 style layout:
    • Pads 1, 2, 3 on the left side at y = -0.95, 0, +0.95 mm.
    • Pads 4, 5 on the right side at y = +0.95, -0.95 mm.
  • Footprint nominal body outline is about 2.90 mm x 1.60 mm with 0.95 mm pitch, consistent with SOT-23-5 / DBV.
  • Footprint name SOT95P280X145-5N is consistent with a 0.95 mm pitch, approximately 2.8 mm span, 1.45 mm height SOT-23-5 package.
Mismatches / Issues Flagged
  1. No pin-number mismatch found. Symbol terminals match the TPS3828 DBV datasheet pinout.
  2. No pad-count mismatch found. Footprint contains 5 pads, matching SOT-23 DBV-5.
  3. Pin descriptions in the project terminals are currently generic/unspecified (Pin Type: Unspecified) rather than datasheet-specific I/O descriptions. Recommended cleanup: set terminal metadata so VDD is input/power, GND is ground, ~RESET is open-drain output, and ~MR/WDI are inputs.
  4. The project description says “Processor Supervisor 0 5.8 V”; datasheet recommended VDD range is 1.1 V to 5.5 V and absolute maximum VDD is 6 V. If “5.8 V” is intended as an operating voltage, it is above the recommended maximum and should be revised. If it is a catalog shorthand near an absolute-limit value, clarify it.
  5. Datasheet URL was available to the datasheet reader but used an insecure HTTP URL. The project was updated to the official HTTPS TI URL: https://www.ti.com/lit/gpn/TPS3828.
  • Update terminal properties/pin descriptions to match datasheet functions.
  • Consider adding a note or example application guidance that VDD should have a 0.1 uF ceramic bypass capacitor nearby when used in a design.
  • Clarify or revise the description voltage text from “0 5.8 V” to recommended operating range 1.1 V to 5.5 V, with absolute maximum 6 V if needed.

Supervisor Open Drain or Open Collector 1 Channel SOT-23-5
The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to make sure proper system reset. The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider. The TPS382x family also offers watchdog time out options of 200ms (TPS3820) and 1.6s (TPS3823, TPS3824, and TPS3828).
• Power-on reset generator with a fixed delay time of 200ms (TPS3823, TPS3824, TPS3825, and TPS3828) or 25ms (TPS3820) • Manual reset input (TPS3820, TPS3823, TPS3825, and TPS3828) • Reset output available in active-low (TPS3820, TPS3823, TPS3824, and TPS3825), active-high (TPS3824 and TPS3825), and open drain (TPS3828) • Supply voltage supervision range: 2.5V, 3V, 3.3V, 5V • Watchdog timer (TPS3820, TPS3823, TPS3824, and TPS3828) • Supply current of 15μA (typical) • 5-pin SOT-23 package • Temperature range: −40°C to 85°C (−40°C to 125°C for TPS3823A-33)
