It includesa synchronous switching DC-DC converter with N-channel high-side and low-side Power MOSFET drivers. The possibility to set the switching frequency with SMBus by choosing one of the two preset values of 350 kHz or 700 kHz assures the best trade-off between power conversion efficiency and PCB cost and size.Integrated loop compensation network and soft- start allow the reduction of the number of external components.The PM6613N integrates 2 charge pumps to drive N-channel ACFET/RBFET and BATFET MOSFETs.The SMBus communication interface is used to set the battery charge current and voltage. The PM6613N charges 2 to 4 series Li-Ion or LiFePO4 cells, for mobile PC applications. It is available in a compact QFN20L 3x3 mm, package.Table 1.Device summaryOrder codePackagePackingPM6613NQFN3x3 20L Tape and reelQFN3x3 20Lwww.st.comTypical application circuitPM6613N2/8Doc ID 022741 Rev 11 Typical application circuitFigure 1.Typical application circuitCBT11uFLOWD1BAT54JFILMBTST+5V+5V+5VB2BC+5VRIOUT10kRSYSCIOUT100nF+5VACNRSB10mRIOUTCADP122uFRACDVR3.9kRACDRV+5VC5V10uFRBATFET3.9kRBATFETGRILU1MRRILLNMD2BAT54JFILMWAKERWAKE110kR+5VRALARMU10kRCADP02.2uF; 25VRFLT13.9RSRPACOKRACDIVL56kR+COUT210uFPH RBT 0RWAKECIN052.2uF; 10VRFLT23.9RALARMRACDIVU430kR+5VRSCLU10kRRACOKU1MRSCLD3STPS2L30ALSGnMOSRBFETSTL56N3LLH51 2 3 45678HIGHRSDAU10kRnMOSLSSTL56N3LLH512345 6 7 8SYSnMOSHSSTL56N3LLH512345 6 7 8SRNGNDBATFETACDIVILIMextB2BRBFETGACPnMOSBATFETSTL56N3LLH512345 6 7 8BATTSYSBATTSCLSDAIOUT_FLTALARM#SDAACOKILIML14.7uHCDC10uFRDC1RRSA10mRCOUT110uFCIN122uFPM6613NTHP21PH1HIGH2BTST3LOW4GND5DCIN6SRP7SRN8BATFET9ACN10ACP11ACDRV12B2B13ACDIV14ILIM15ACOK16 IOUT17 ALARM#18 SCL19 SDA20CBT220nFADPPHnMOSACFETSTL56N3LLH51 2 3 45678ADPAM10245v1PM6613NDevice pinoutDoc ID 022741 Rev 13/82 Device pinoutFigure 2.PM6613N pinoutPM6613NPH1HIGH2BTST3LOW4GND5DCIN6SRP7SRN8BATFET9ACN10ACP11ACDRV12B2B13ACDIV14ILIM15ACOK16IOUT17ALARM#18SCL19SDA20AM10244v1Package mechanical dataPM6613N4/8Doc ID 022741 Rev 13 Package mechanical dataIn order to meet environmental requirements, ST offers these devices in different grades of ECOPACK packages, depending on their level of environmental compliance.
