The MAX1555EZK+T from Analog Devices (formerly Maxim Integrated) is a versatile single-cell lithium-ion battery charger IC designed for applications requiring charging from both USB and AC adapter sources. It operates with no external FETs or diodes and accepts input voltages up to 7V.
This IC features on-chip thermal limiting, which simplifies PC board layout and allows for an optimal charging rate without shutting down. When thermal limits are reached, the charger progressively reduces charging current. The MAX1555EZK+T indicates charging status via a CHG output.
With USB connected, the charge current is set to a maximum of 100mA, enabling charging from both powered and unpowered USB hubs without port communication. When an AC adapter is connected, the charging current is typically 280mA. No input-blocking diodes are required to prevent battery drain.
The MAX1555EZK+T is available in a 5-pin Thin SOT23 package and operates over an industrial temperature range of -40°C to +85°C. Its compact size and dual-input capability make it suitable for portable devices such as PDAs, cell phones, wireless appliances, and digital cameras.
