The MAX8934AETI+T from Analog Devices is a dual-input linear battery charger IC with a Smart Power Selector, designed for safely charging single Li+/Li-Poly cells according to JEITA recommendations. It monitors battery temperature during charging and automatically adjusts current and termination voltage. The device also monitors battery temperature during discharge, providing an over-temperature warning flag.
Key electrical specifications include a maximum charge current of 1.5A, a DC current limit of 2A, and a USB input current limit settable to 100mA or 500mA. It supports overvoltage protection up to 16V (DC) and 9V (USB). The MAX8934A variant provides a SYS output voltage of 5.3V.
This IC operates within a temperature range of -40°C to 85°C and is available in a 28-WFQFN exposed pad package, suitable for surface mounting. It integrates all necessary power switches, eliminating the need for external MOSFETs, and features an always-on 3.3V LDO for system power.
Applications include PDAs, portable media players, digital cameras, and handheld game systems that require efficient and safe battery management.
