MAX1551EZK+T Description

Short technical summary and product information.

The MAX1551EZK+T is a single-cell lithium-ion battery charger IC designed by Analog Devices (formerly Maxim Integrated). It efficiently charges a Li+ battery from either a USB port or an AC adapter, simplifying power management in portable devices. This IC operates with no external FETs or diodes and accepts input voltages up to 7V from AC adapters and up to 6V from USB sources.

 

Key features include on-chip thermal limiting, which progressively reduces charging current when thermal limits are reached, rather than shutting down, thus simplifying PC board layout and optimizing charging rates. The MAX1551 includes a POK output to indicate input power presence, while the MAX1555 variant features a CHG output for charging status indication. Charging current is set to a maximum of 100mA from USB and a typical of 280mA when an AC adapter is connected. No input-blocking diodes are required, preventing battery drain.

 

This component is available in a compact 5-pin Thin SOT-23 package, making it suitable for space-constrained applications. It operates reliably over a wide temperature range of -40°C to +85°C. Applications include PDAs, wireless appliances, cell phones, and digital cameras.

 

The MAX1551EZK+T is designed for surface mount applications and comes in a SOT-23-5 Thin package.
