Is there a pin-compatible replacement for COS4428SR?

UCC27324DR(UMW) and TC4424AVOA713-JSM are both available in the same SOP-8 package and are likely pin-compatible. However, this must be confirmed by comparing datasheets as no official cross-reference guarantees it.

What risks should I check before replacing COS4428SR?

Before replacing COS4428SR, check three main things: 1) Pinout: Ensure the replacement's pin functions match the original. 2) Logic: Confirm the replacement is also a non-inverting driver. 3) Speed: Verify the propagation delay and rise/fall times are acceptable for your circuit's operating frequency.

COS4428SR Alternatives, Datasheet & Cross Reference | COSINE

The COS4428SR is a 1.5A dual non-inverting MOSFET driver in a SOP-8 package. While several alternatives exist with similar form factors, careful review of pinout, current rating, and switching speed is essential for a successful replacement.

Electrical riskmedium

Timing parameters like propagation delay can differ and must be evaluated for the specific application.

Package risklow

Multiple candidates exist in the same SOP-8 package, but pinout must be verified from datasheets.

Can it be replaced directly?

There are several potential alternatives for COS4428SR, but no guaranteed drop-in replacement has been verified. UCC27324DR(UMW) is a strong candidate that requires pinout confirmation.

Best replacement path

UCC27324DR(UMW) is a promising upgrade path, offering higher current and a wider temperature range. However, pinout verification is mandatory.

Main risk

The primary risk is timing incompatibility. Alternatives may have different propagation delays or rise/fall times, which can affect circuit performance, especially at high frequencies.

Recommended alternatives

A potential upgrade with higher current drive and wider temperature range in the same SOP-8 package.
