It integrates a constant-current, constant-voltage charge controller with an internal power-FET and a programmable charge current up to 2 A. The device accepts a USB input and operates from a supply voltage up to 16 V, covering both standard USB bus power and higher-voltage wall adapters. Over-voltage fault protection on the input prevents damage from out-of-spec adapters. The 4.1 V battery pack voltage targets standard Li-ion cells, and the programmable charge current and timer allow the designer to tailor the charge profile to the cell capacity and thermal budget of the enclosure. ## Package, footprint and reflow considerations The supplier device package is 28-TQFN (4x4). Surface-mount assembly with a standard lead-free reflow profile is expected; the tube packaging means the parts are delivered in anti-static tubes suitable for tray-fed pick-and-place machines.","metaTitle":"MAX8903EETI+ Analog Devices Battery Charger IC, 2A, 28-TQFN","metaDescription":"MAX8903EETI+ Li-Ion battery charger IC from Analog Devices, Smart Power Selector series. 2A programmable charge current, 16V supply max, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"Smart Power Selector™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Smart Power Selector™","Package":"Tube","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"28-WFQFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"4.1V","Charge Current - Max":"2A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"28-TQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.60000","currency":"USD"},{"qty":10,"price":"$6.86200","currency":"USD"},{"qty":25,"price":"$6.54280","currency":"USD"},{"qty":100,"price":"$5.68100","currency":"USD"},{"qty":250,"price":"$5.42572","currency":"USD"},{"qty":500,"price":"$4.94698","currency":"USD"},{"qty":1000,"price":"$4.30866","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Analog Devices provide for MAX8903EETI+?","answer":"The MAX8903EETI+ is ROHS3 compliant.
