COSINE Tier-1 distributor Jarwey｜3.3 V logic supply is printed only on COS2113PBF
Jarwey is a COSINE Tier-1 distributor and can help with half-bridge and low-side MOSFET gate-driver selection, datasheets, samples, and small-lot lead time.
The decision on this page: the words logic 3.3~20 V appear on the function line of COS2113PBF only. COS2181STRPBF is also a 600 V high-side/low-side driver with IO ±2.5 A and HIN/LIN, and its function line does not print a logic-supply range. The low-side COS4426SR prints Vcc 4.5~25 V. That is the driver supply window, not a 3.3 V input-high level. None of these three pages prints VIH or VIL.
The published 600 V half-bridge family note puts a 3.3–20 V logic supply, a 10–20 V gate-drive window, and ±5 V logic-to-power ground offset in the category feature line. Those three phrases do not travel onto every function line. This note does not rebuild that dead-time and package table.
None of the four pages below offers a downloadable datasheet. Ask Jarwey for the datasheet. IR2113 / IR2110, IR2181, IR2183, and TC4426 are the anchor part numbers printed on the pages. They still need a board check. They are not unverified drop-in replacements.
What each function line actually prints
| Part | Package field | Function line | Not on that function line | Page |
|---|---|---|---|---|
| COS2113PBF | DIP-14 | 600 V high-side/low-side; IO ±2.5 A; logic 3.3~20 V; HIN/LIN. Anchor line: IR2113 / IR2110 (verify) | No 10–20 V gate window, no ±5 V ground offset, no VIH/VIL, no dead time | 975 |
| COS2181STRPBF | SOP-8 | 600 V high-side/low-side; IO ±2.5 A; HIN/LIN; SOP-8. Anchor line: IR2181 (verify) | No logic 3.3~20 V, no gate-voltage window, no ground offset, no dead time | 976 |
| COS2183S | SOP-8 | 600 V high-side/low-side; fixed dead time about 400 ns; shoot-through prevention. Anchor line: IR2183 (verify) | No IO ±2.5 A, no HIN/LIN, no logic 3.3~20 V | 977 |
| COS4426SR | SOP-8 | 1.5 A dual inverting MOSFET driver; Vcc 4.5~25 V; tr/tf about 11 ns. Anchor line: TC4426 / IR4426 (verify) | No separate logic rail. The 4.5 V Vcc floor is not VIH | 964 |
The 400 ns figure only records what the COS2183S function line prints. Dead time versus an external blanking interval stays in the existing half-bridge note. COS4427SR prints the same tr/tf of about 11 ns on the non-inverting dual page. That number is an edge time, not a logic threshold.
Checklist before you pick a rail
- Read the function line: a search for logic 3.3~20 V currently lands on COS2113PBF. Do not treat the family feature paragraph as that line.
- Three phrases that do not move: 3.3–20 V logic, 10–20 V gate drive, and ±5 V ground offset are absent from the COS2181STRPBF, COS2183S, and COS4426SR function lines.
- 3.3 V MCU: COS2113PBF is the page that states a 3.3~20 V logic supply. VIH, UVLO, and the bootstrap capacitor are not given on the page. Confirm them on the datasheet from Jarwey.
- Same IO, different sentence: COS2181STRPBF and COS2113PBF both print HIN/LIN and IO ±2.5 A. Packages are SOP-8 and DIP-14. Matching current does not add the logic-supply sentence.
- Low-side Vcc: 4.5~25 V on COS4426SR is the supply pin. The page does not say a 3.3 V GPIO may drive the input. About 11 ns tr/tf describes the edge only.
- Dead-time page: if the requirement is a fixed dead time, use COS2183S and the existing half-bridge note. Do not add a logic-supply sentence to that function line.
- Datasheet and samples: ask Jarwey for the datasheet. Samples, small lots, and lead time can be scheduled against the project.
