The MAX8934AETI+ from Analog Devices is a sophisticated dual-input linear battery charger designed for single Li+/Li-Poly cells. It incorporates a Smart Power Selector, eliminating the need for external MOSFETs and optimizing power usage from USB or AC adapter inputs. This IC automatically adjusts fast-charge current and termination voltage based on battery temperature, adhering to JEITA recommendations.
Key electrical specifications include a charge current of up to 1.5A, a system voltage of 5.3V, and a programmable current limit of 2A. It also features overvoltage protection (OVP) up to 16V (DC) and 9V (USB), and an always-on 3.3V LDO. The device monitors battery temperature during discharge, providing an over-temperature warning flag.
Packaged in a 28-TQFN (4x4) with a surface mount type, the MAX8934AETI+ operates within a temperature range of -40°C to 85°C. Its features include independent setting of input current limit and battery charge current limit, automatic input selection, and thermal regulation to prevent overheating. This makes it suitable for applications like PDAs, portable media players, digital cameras, and handheld game systems.
