Specs side by side
2 parts compared · 14 differing specs across 14 total parameters.
| Parameter | ||
|---|---|---|
| Supply voltage | - | 20V-class drain rating; the pair defines the pack current ceiling, not the IC. |
| Memory & Peripherals | - | The diagnostic order on a dead pack: measure the two FETs for a shorted channel first (the common failure), then the gate drive nets (DO and CO), then the controller - replacing the SOT-23-6 first is the parts-cannon approach. |
| Case | SOT-23-6 | TSSOP-8 |
| Compatibility Level | - | 100% Drop-in (Zero Code Change) |
| Component Category | Battery Protection ICs | - |
| Core & Architecture | - | The dual N-channel MOSFET that does the actual cutting: two FETs at roughly 30 milliohms each and a 3.3A-class continuous ceiling, gated by the DW01 DO and CO lines - the half that dies in short-circuit events while the controller survives. |
| Firmware Notes | - | The pair rule: replace the switch with the protector when either has failed - a fresh IC driving a degraded FET re-fails on the next load, and a fresh FET under a damaged controller never gets its gate signal. |
| Hardware Notes | - | TSSOP-8 with the standard dual-FET pinout; second-source brands interchange by function - verify Rds(on) class and current rating. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The DW01A protector and its 8205A dual-MOSFET partner are the single-cell Li-ion protection circuit that ships inside power banks, TWS earbuds, wearables and a billion no-name 18650 packs: the DW01A senses cell voltage through the SOT-23-6 pinout and drives the two back-to-back N-channel FETs that sit in the pack negative line, cutting charge at about 4.30V and discharge at about 2.40V. The repair reality is that this is a PAIR with one name in every conversation and two die on one board - and the threshold LETTER matters: A, B and C variants guard different cell chemistries with different windows, and the wrong letter either trips early or never protects. | - |
