Product details

The Maxim Integrated MAX1686HEUA+ is a single-output charge pump regulator designed to generate a regulated 5 V output from a lithium-ion battery range of 2.7 V to 4.2 V. Its primary application is biasing SIM cards in mobile handsets, modems, and embedded wireless modules where the system rail is 3.3 V or 3.8 V and the SIM requires a clean 5 V supply.

Package and footprint — 8-pin uMAX/uSOP, 3.00 mm width

The MAX1686HEUA+ is supplied in an 8-TSSOP / 8-MSOP package with a 0.118" (3.00 mm) body width, also referred to as 8-uMAX or 8-uSOP by Maxim.

Frequently asked questions

What is the typical application of MAX1686HEUA+?

The MAX1686HEUA+ is a charge pump regulator specifically intended for biasing SIM cards. It converts a 2.7 V to 4.2 V input — typical of a single-cell Li-ion battery — to a regulated 5 V output for the SIM card supply rail.
