Maxim MAX8677AETG+

Литий-ионный1.5A-40°C ~ 85°C (TA)

Overview

The MAX8677AETG+ is an integrated 1-cell Li+ charger and Smart Power Selector with dual (DC and USB) power inputs. It can operate with either separate inputs for USB and AC adapter power*, or from a single input that accepts both. All power switches for charging and switching the load between battery and external power are included on-chip. No external MOSFETs are required. The MAX8677AETG+ features a Smart Power Selector to make the best use of limited USB or adapter power. The battery charge current and input current limit are independently set up to 1.5A and 2A, respectively. Input power not used by the system charges the battery. USB input current can be set to 100mA or 500mA. Automatic input selection switches the system load from battery to external power. Other features include overvoltage protection (OVP), charge status and fault outputs, power-OK monitors, charge timer, and battery thermistor monitor. Additionally, on-chip thermal limiting reduces the battery charge rate to prevent overheating. The MAX8677AETG+ is available in a 4mm x 4mm, 24-pin TQFN-EP package.
