It delivers up to 2A charge current to battery packs rated to 20V max, powered from a supply rail up to 28V. The 20-TSSOP with exposed pad (EP) package keeps the thermal path short for sustained charging at the full 2A. Over-voltage fault protection on the output catches a failed sense resistor or open-cell condition before the pack sees excess voltage. ## Package and mounting Surface-mount 20-TSSOP with exposed pad (0.173\" body width, 4.40 mm). The exposed pad must be soldered to a copper plane on the PCB for thermal dissipation — without it, the 2A charge current will push the junction above the rated operating temperature. The Bulk shipping medium suits prototype runs and small-batch production; for reel quantities, check the LT1769IFE#PBF variant.","metaTitle":"LT1769IFE#TRPBF Multi-Chemistry Battery Charger IC, 2A","metaDescription":"LT1769IFE#TRPBF from Analog Devices: constant-current programmable charger for Li-Ion, NiMH, NiCd, lead-acid. 2A max, 28V supply, over-voltage protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"20V (Max)","Charge Current - Max":"2A","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"28V","Supplier Device Package":"20-TSSOP-EP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.8","stockQuantity":0,"priceTiers":[{"qty":28,"price":"$10.80000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/354668da04d74b7f17c297f6c659b140.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LT1769IFE#TRPBF charge Li-Ion batteries?","answer":"Yes, the IC supports multi-chemistry charging including Li-Ion.
