Its 500 mA maximum charge current matches the USB 2.0 standard port limit, so a simple USB VBUS connection delivers the full rated current without negotiation. Charge current is constant and programmable via an external resistor, with a programmable timer for termination. The 4.2 V battery pack voltage is fixed — no cell-balancing or multi-chemistry options; this part is strictly for single-cell Li-Ion or Li-Polymer packs. ## Temperature range and fault protection Over-temperature fault protection is built in, shutting down the pass device if the die exceeds the safe limit. Supply voltage max is 6.5 V, so a 5 V USB rail or a regulated 5 V wall adapter is fine. ## Obsolete — sourcing reality TI lists the BQ24023DRCRG4 as obsolete. No official successor part number appears on the lifecycle record.","metaTitle":"BQ24023DRCRG4 Li-Ion/Polymer Charger, 500 mA, USB, Obsolete","metaDescription":"Texas Instruments BQ24023DRCRG4 single-cell Li-Ion/Polymer battery charger with USB interface. 500 mA max charge current, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™-II","Package":"Tape & Reel (TR)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24023","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"10-VSON (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$66.8400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5231bfebd8a96493d69d3ffb619779e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24023DRCRG4 obsolete?","answer":"Yes, TI has marked the BQ24023DRCRG4 as obsolete."},{"question":"What is the maximum charge current of BQ24023DRCRG4?","answer":"The maximum charge current is 500 mA, constant and programmable via an external resistor.
