MAXIM INTEGRATED / ANALOG DEVICES MAX1555EZKT Lithium-ion Battery Charger
The MAX1555EZK+T is a dual-input, lithium-ion battery charger designed for portable devices, featuring a 5-pin SOT-23 package. It supports charging from USB or AC adapters with input voltages up to 7V, operating without external FETs or diodes. The device includes on-chip thermal limiting that allows for optimal charging rates by reducing current when thermal limits are approached, rather than shutting down. When powered via USB, it provides a maximum charge current of 100mA, enabling charging from both powered and unpowered USB hubs without the need for port communication. When connected to DC power, the charging current is typically 280mA, and input blocking diodes are unnecessary to prevent battery drain. It features an active-low charge status indicator, auto-switching between power sources, and operates within a temperature range of -40°C to 85°C. Suitable for use in cell phones, digital cameras, PDAs, and wireless appliances.
