Product details

Single-cell Li-ion charger in a TSOT-23-5

The MAX1551EZK+T is a single-cell Lithium-Ion battery charger IC from Analog Devices. It terminates at 4.2 V and delivers up to 340 mA charge current from a USB supply. The TSOT-23-5 package keeps the footprint small for portable devices like Bluetooth headsets, wearables, and handheld instruments. Operating temperature covers -40°C to 85°C, so it handles outdoor and industrial ambient conditions.

Package and mounting

Housed in a TSOT-23-5, this is a surface-mount part. The thin profile suits tight enclosures. Reel and cut-tape options are listed; store the reels dry if the moisture-sensitive level (MSL) on the reel label calls for it — typical for this package class.
