The 4.2 V battery pack voltage is fixed internally, so this part targets standard Li-ion cells, not LiFePO4. ## Programmable charge current and timer Charge current and safety timer are programmable via external resistors, giving the designer control over charge rate and termination timing. The 13.5 V maximum supply voltage allows operation from a standard 5 V USB or higher-voltage wall adapter. ## Active lifecycle – no obsolescence risk The part ships in a Tube, surface-mount 8-HVSSOP package with exposed pad for thermal management. ## Protection and temperature range Built-in fault protection covers over-temperature and short-circuit conditions, reducing external component count and improving reliability in portable designs.","metaTitle":"BQ24202DGNG4 Texas Instruments Li-Ion Charger IC – Active","metaDescription":"Texas Instruments BQ24202DGNG4 single-cell Li-Ion/Polymer linear charger IC. 500 mA max charge current, 4.2 V battery voltage, -40°C to 125°C range.","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":"Tube","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ24202","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"8-HVSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8d269c85a61d814b6ccabe42b85d2ae7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BQ24202DGNG4 charge LiFePO4 batteries?","answer":"No. The BQ24202DGNG4 is designed for single-cell Lithium Ion/Polymer batteries with a fixed 4.2 V battery pack voltage. LiFePO4 cells require a different charge voltage (typically 3.6 V per cell) and are not supported."},{"question":"How to program the charge current on BQ24202DGNG4?","answer":"The charge current is set by an external resistor connected to the ISET pin, per the formula in the datasheet. The timer is also programmable via an external capacitor on the TMR pin."},{"question":"Is there a pin-compatible alternative to BQ24202DGNG4?","answer":"Within the BQ24202 family, the base product number BQ24202 covers several package and temperature variants.
