Product details

Package and footprint — tiny DFN for tight boards

Housed in a 6-WFDFN package with the supplier device package specified as 6-µDFN measuring 1.5x1 mm, this is a very small surface-mount part. The 1.5x1 mm footprint is about the size of a grain of pepper, which helps when board real estate is at a premium — think wearable devices, compact IoT modules, or multi-port USB hubs where every square millimetre counts. The surface-mount package is compatible with standard reflow soldering processes.

Lifecycle and sourcing — active, no end-of-life concern

For a BOM line, that removes the obsolescence risk that drives last-time-buy scrambles. The part is ROHS3 compliant, so it meets the latest EU restriction requirements without a waiver. Sourcing is straightforward through independent distribution: we quote this part to order against an RFQ, confirming availability and current pricing at quote time. There is no single-source exposure — the part is widely available through multiple channels.

Frequently asked questions

What is the closest pin-compatible alternative to MAX4831ELT+T?

The MAX4830ELT+T is the closest sibling in the same family. The primary difference is the current-limit threshold — the MAX4831ELT+T is set for 50mA, while the MAX4830ELT+T uses a different factory-programmed limit. Both share the same 6-µDFN (1.5x1) package and pinout, so a PCB swap is straightforward if the current requirement differs.

Can MAX4831ELT+T be used in USB power delivery?

Yes, the 2.3V–5.5V input range covers standard USB bus voltages (5V nominal), and the 50mA output is suitable for low-power USB peripherals or dedicated charging ports that need current limiting. For higher-power USB PD applications (3A+), a different current limiter with a higher output rating would be needed.
