DS6091 Datasheet | DSTECH

Description Features The DS6091 series are protection ICs for rechargeable - Provide plete protection single-cell lithium ion ( Li + ) battery away from - Integrate Advanced Power MOSFET with Equivalent overcharge / discharge voltage or excessive load of 35mΩ RSS(ON) currents. It also includes a short-circuit protector to - Over-temperature Protection prevent large external short-circuit currents. - Over-charge Current Protection These ICs are posed of two voltage detectors, - Over-discharge Current Protection reference cells, delay circuits, short circuit protectors, - Load Short Circuiting Protection logic circuits and MOSFET switches. - High-Accuracy Voltage Detection When the charging voltage exceeds the detector threshold from a low value to a value higher than VDET1, the MOSFET switch is turned off. After detecting - Low Current Consumption - Operation Mode : 1.0u A - Power-down Mode : 0.1μA overcharge, when the VBAT voltage drops below the - Delay Times are generated inside "VREL1" level, or when the charger is disconnected - DFN1x1-4L Package Available from the charger to VBAT, it can be reset and the MOSFET switch is turned on. When the discharge voltage is below the detector threshold from a high value to another lower than Applications VDET2, the MOSFET switch is turned off after an - Laptop, Palmtops and PDAs internal fixed delay time. - Smart Phones After the DS6091 series detects the over-discharge - MP3 Players + voltage, connect the charger to the battery pack, and - Low-Power Handheld Devices when the battery power supply voltage is higher than - TWS & E-Cig the over-discharge detector threshold, the MOSFET - One Cell Lithium-ion Battery Pack switch is turned on. After the internal fixed delay time acpanied by the built-in over-current detector, the over-load current can be sensed and cut off by the MOSFET switch being Pin Configurations turned off. Once the excess current is detected, it can be released by...
