The PWM controller uses a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. Charging current is programmable with a sense resistor and programming resistor to ±4% typical accuracy. Charging current can be monitored as a voltage across the programming resistor. An external resistor divider and precision internal reference set the final float voltage. It includes a thermistor sensor input that will suspend charging if an unsafe temperature condition is detected and will automatically resume charging when battery temperature returns to within safe limits; a FAULT pin indicates this condition. A FLAG pin indicates when charging current has decreased below 10% of the programmed current. It is used in application such as notebook computers, portable instruments, battery backup systems etc.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGeneral purpose charger controller\u003c\/li\u003e\n\u003cli\u003eHigh conversion efficiency upto 96%\u003c\/li\u003e\n\u003cli\u003eOutput currents exceeding 4A, voltage accuracy is ±0.8%\u003c\/li\u003e\n\u003cli\u003eAC adapter current limiting maximizes charge rate\u003c\/li\u003e\n\u003cli\u003eThermistor input for temperature qualified charging\u003c\/li\u003e\n\u003cli\u003eWide input voltage range is 6V to 28V, wide output voltage is 3V to 28V\u003c\/li\u003e\n\u003cli\u003eCharging current monitor output\u003c\/li\u003e\n\u003cli\u003eRegulator maximum duty cycle is 99% typ at (VCSP = VBAT, TA = 25°C)\u003c\/li\u003e\n\u003cli\u003eOperating temperature is -40°C to 125°C\u003c\/li\u003e\n\u003cli\u003ePackage style is 20-lead narrow plastic SSOP\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eADI products are only authorized (and sold) for use by the customer and are not to be resold or otherwise passed on to any third party\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003ch4\u003eProduct details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Type\u003c\/td\u003e\n\u003ctd\u003eLead Acid, LiFePO4, Li-Ion, Li-Pol, NiCd, NiMH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Charge Voltage\u003c\/td\u003e\n\u003ctd\u003e28V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIC Case \/ Package\u003c\/td\u003e\n\u003ctd\u003eSSOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. of Cells\u003c\/td\u003e\n\u003ctd\u003e18Cells\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Max\u003c\/td\u003e\n\u003ctd\u003e125°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Range\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSVHC\u003c\/td\u003e\n\u003ctd\u003eNo SVHC (04-Feb-2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e28V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharge Current\u003c\/td\u003e\n\u003ctd\u003e4A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. of Pins\u003c\/td\u003e\n\u003ctd\u003e20Pins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Min\u003c\/td\u003e\n\u003ctd\u003e-40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIC Mounting\u003c\/td\u003e\n\u003ctd\u003eSurface Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMSL\u003c\/td\u003e\n\u003ctd\u003eMSL 1 - Unlimited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch4\u003eOther details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eANALOG DEVICES\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eLTC4008EGN#PBF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnical Data Sheet (203.87KB) EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"https:\/\/www.analog.com\/media\/en\/technical-documentation\/data-sheets\/ltc4008.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eView or download\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Change Notice (73.96KB) EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"https:\/\/www.farnell.com\/datasheets\/4419217.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eView or download\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
