The 20-HTSSOP package has an exposed thermal pad — the 1.2A ceiling assumes adequate PCB copper area to pull heat off the die; in a tight layout the charge current may need to be set lower to stay below the over-temperature shutdown threshold. ## Programmable current and timer — no I2C needed Charge current and safety timer are set with external resistors, so the BQ24003PWPR fits into designs where a simple analog control loop is preferred over a digital bus. The timer provides a backup termination if the battery never reaches the 4.2V regulation voltage within the programmed window. ## Protection and temperature range On-chip over-temperature protection shuts down the charger if the die temperature exceeds the safe limit — a useful safeguard when charging at the full 1.2A in a warm enclosure. The device is specified over -40°C to 70°C ambient, covering consumer and industrial indoor equipment where the charger sits near the battery pack.","metaTitle":"BQ24003PWPR Li-Ion Charger, 1.2A Max, 20-HTSSOP","metaDescription":"Texas Instruments BQ24003PWPR single-cell Li-Ion charger, 4.2V pack voltage, 1.2A max charge current, programmable current and timer, over-temp 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)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant","Base Product Number":"BQ24003","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.2A","Operating Temperature":"-40°C~70°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"10V","Supplier Device Package":"20-HTSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3220","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6312853505ca2072a37f28e7f44f90ba.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24003PWPR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24003PWPR when reusing this data.
