G2206 has usb power source detection and jeita compliant. G2206 also has auto ntc-r 100k /10k detection circuit. ordering information order number marking temp. range package (green) G2206rg1u 2206 -35 c~+85 c tqfn5x5-40 note: rg:tqfn5x5-40 1: bonding code u: tape & reel pin configuration pvcc45 fb4 seq lx4 onpmu lx5 /int vofb5 vin8 sda scl rtcout pvcc1 lx1 iset vout6 lx6 /chg vout7 vin7 dm dp vin sys sys bat bat 1 2 3 4 5 6 7 8 9 10 ts fb3 pvcc2 lx2d vout2 fb2 vout8 11 12 13 14 15 16 17 18 19 20 G2206 tqfn5x5-40 thermal pad 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 lx3 pvcc3 /chg2 vp note: recommend connecting the thermal pad to the ground for excellent power dissipation. wake lx2u pvcc45 fb4 seq lx4 onpmu lx5 /int vofb5 vin8 sda scl rtcout pvcc1 lx1 iset vout6 lx6 /chg vout7 vin7 dm dp vin sys sys bat bat 1 2 3 4 5 6 7 8 9 10 ts fb3 pvcc2 lx2d vout2 fb2 vout8 11 12 13 14 15 16 17 18 19 20 G2206 tqfn5x5-40 thermal pad 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 lx3 pvcc3 /chg2 vp note: recommend connecting the thermal pad to the ground for excellent power dissipation. wake lx2u
