Overcurrent protection trips when the discharge current exceeds a threshold — the exact threshold and response time are set internally, so the designer does not need external sense resistors or programming resistors. Over-voltage protection prevents the cell from charging above its safe ceiling; under-voltage protection disconnects the load when the cell voltage drops too low, preventing deep discharge damage. Short-circuit detection is a fast-acting separate comparator that triggers a hard disconnect. Because these thresholds are factory-trimmed, the part is a drop-in fit for a standard Li-ion cell — no calibration step in production.","metaTitle":"TI BQ29737DSER Battery Protection IC, 1-Cell Li-Ion, 6-WSON","metaDescription":"Texas Instruments BQ29737DSER single-cell Li-Ion/Polymer battery protection IC with overcurrent, over/under voltage, and short-circuit protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Battery Protection","Mounting Type":"Surface Mount","Package / Case":"6-WFDFN","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over/Under Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"6-WSON (1.5x1.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6","priceTiers":[{"qty":1,"price":"$0.60000","currency":"USD"},{"qty":10,"price":"$0.51500","currency":"USD"},{"qty":25,"price":"$0.48080","currency":"USD"},{"qty":100,"price":"$0.38460","currency":"USD"},{"qty":250,"price":"$0.35712","currency":"USD"},{"qty":500,"price":"$0.30220","currency":"USD"},{"qty":1000,"price":"$0.23351","currency":"USD"},{"qty":3000,"price":"$0.21291","currency":"USD"},{"qty":6000,"price":"$0.19917","currency":"USD"},{"qty":15000,"price":"$0.18544","currency":"USD"},{"qty":30000,"price":"$0.17582","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/675a74142e5b0eed774656b6d9cdd1c0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ29737DSER/alternatives.json"},"ai":{"faq":[{"question":"Does BQ29737DSER have overcurrent protection?","answer":"Yes.
