FFF CompatibilityPins 1-8 share the core power management pin assignments, but comes in an ESOP-8 package with an exposed center pad.ESOP-8 package form factor has identical pin pitch but includes an exposed pad underneath.Provides equivalent 5V/1A boost output and matching 2.8V low-battery cutoff, with upgraded 1A charging rate.Pins 1-8 share the same pin assignments, but the ESOP-8 package includes an exposed thermal pad requiring PCB thermal pad grounding consideration.ESOP-8 package form factor is physically compatible with SOP-8 footprint, but features a thermal pad underneath.Electrically identical in performance (5V/1A discharge output, 0.8A linear charge current, 2.85V cutoff).
AI Summary

TP4333 by TPOWER: 5V SOP-8 Power Management - Specialized .

TP4336 is an upgraded single-chip power bank SOC from TPOWER in an ESOP-8 package. It shares the baseline architecture and pin mapping of the TP4333 while increasing the maximum charge current from 0.8A to 1.0A and adding pass-through power path support.

  • Same family architecture and pin functions (OUT, BAT, SW, GND, SWT, VDD)
  • Higher 1.0A charging current (vs 0.8A on TP4333) for faster battery charging
  • Supports power-path management (charging battery and powering load simultaneously)
  • Package is ESOP-8 with exposed thermal pad (TP4333 is standard SOP-8).

TP4366E is the thermally enhanced ESOP-8 variant of the TP4366 series. It maintains identical pin assignments on pins 1 to 8 and identical electrical specs as the TP4333, but introduces an exposed bottom pad for improved heat dissipation.

  • Same family function and electrical ratings (0.8A charging, 1A output at 5V)
  • Enhanced thermal performance via Exposed Pad (ESOP-8 package)
  • Identical pin mapping on Pins 1 through 8
  • Requires an exposed copper ground pad on the PCB for optimal thermal dissipation, whereas TP4333 uses standard SOP-8 without a thermal pad.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
