The under-voltage lockout prevents the PMIC from operating with a sagging input that would otherwise cause erratic rail sequencing — a common failure in battery-powered designs that would normally require an external voltage monitor. ## Package and thermal land — 40-VQFN with exposed pad Supplied in a 40-VFQFN exposed-pad package, the supplier device package is 40-VQFN measuring 6x6 mm. Without it, the junction temperature rises above the 85°C ambient ceiling even at moderate load.","metaTitle":"TPS65020RHARG4 PMIC, Li-Ion Power Management, I²C","metaDescription":"Texas Instruments TPS65020RHARG4 power management IC with I²C interface, Li-Ion/Polymer battery support, over-temp and UVLO protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Function":"Power Management","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"40-VFQFN Exposed Pad","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Under Voltage","Battery Chemistry":"Lithium Ion/Polymer","Base Product Number":"TPS65020","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"40-VQFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.7900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5b81f656cc11887eb1741d3c796f9aa1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65020RHARG4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TPS65020RHARG4?","answer":"No pin-compatible alternative is listed on the official cross-reference record for this part.
