It supports a maximum charge current of 2 A and a battery pack voltage up to 4.44 V, with programmable timer-based charge termination. ## Fault protection and shutdown On-chip fault protection covers over-temperature and over-voltage events, eliminating the need for external supervisory circuits in most single-cell portable designs. ## NRND — plan the BOM transition New production builds should evaluate the current-generation single-cell charger family for a drop-in or layout-compatible replacement.","metaTitle":"BQ24257RGET Battery Charger IC, I²C/USB, 2A, NRND","metaDescription":"Texas Instruments BQ24257RGET single-cell battery charger with I²C/USB interface, 2A max charge current, VQFN-24.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C, USB","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Not For New Designs","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24257","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"2A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/17ba585d526919b204848b207beec98c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24257RGET obsolete?","answer":"It remains available for existing production through independent channels while stock lasts."},{"question":"Does BQ24257RGET support I²C?","answer":"Yes, the BQ24257RGET uses an I²C interface to program charge current, timer settings, and other parameters.
