It delivers a constant charge current up to 1.2 A and terminates at a battery pack voltage of 8.4 V, which is the standard full-charge voltage for a 2S stack. The constant-current profile simplifies the charge algorithm — no need for external current-sense resistors or complex loop compensation. ## Programmable current and timer for charge control Charge current and a safety timer are programmable via external resistors, letting you set the charge rate to match the battery capacity and the timeout to prevent overcharge if termination is missed. The maximum supply voltage is 10 V, so the input rail must be regulated — a 5 V USB port alone won't reach the 8.4 V pack voltage; a boost converter or 9–10 V wall adapter is required. ## Over-temperature protection and fault handling The IC includes over-temperature fault protection that shuts down the charger if the die exceeds the thermal limit — a critical safeguard when charging at 1.2 A in a compact 20-HTSSOP footprint without active cooling. The battery chemistry is lithium ion, so it is not compatible with LiFePO4 or NiMH cells without a different termination voltage.","metaTitle":"BQ24005PWP Texas Instruments Li-Ion Battery Charger IC –","metaDescription":"Texas Instruments BQ24005PWP Li-Ion battery charger IC for 2-cell packs, 1.2A max charge current, 8.4V pack voltage, -40°C to 70°C, 20-HTSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Number of Cells":"2","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant","Base Product Number":"BQ24005","Battery Pack Voltage":"8.4V","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":"$6.1800","priceTiers":[{"qty":1,"price":"$6.18000","currency":"USD"},{"qty":10,"price":"$5.55000","currency":"USD"},{"qty":25,"price":"$5.24720","currency":"USD"},{"qty":100,"price":"$4.54740","currency":"USD"},{"qty":250,"price":"$4.31420","currency":"USD"},{"qty":500,"price":"$3.87112","currency":"USD"},{"qty":1000,"price":"$3.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/425c602be662b5d8c5fb48b6736e9d29.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24005PWP/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24005PWP?","answer":"The maximum charge current is 1.2 A, set by an external resistor.
