The converter has 16 30 (MC13783) resp. 12 (MC13892) channels which can be used in different modes. The 31 A/D converter has a resolution of 2.25mV. 32 33 Some channels can be used as General Purpose inputs or in a dedicated mode with 34 a chip internal scaling applied . 35 36 Currently the driver only supports the Application Supply channel (BP / BPSNS), 37 the General Purpose inputs and touchscreen. 38 39 See the following tables for the meaning of the different channels and their 40 chip internal scaling: 41 42 - MC13783: 43 44 ======= =============================================== =============== ======= 45 Channel Signal Input Range Scaling 46 ======= =============================================== =============== ======= 47 0 Battery Voltage (BATT) 2.50 - 4.65V -2.40V 48 1 Battery Current (BATT - BATTISNS) -50 - 50 mV x20 49 2 Application Supply (BP) 2.50 - 4.65V -2.40V 50 3 Charger Voltage (CHRGRAW) 0 - 10V / /5 51 0 - 20V /10 52 4 Charger Current (CHRGISNSP-CHRGISNSN) -0.25 - 0.25V x4 53 5 General Purpose ADIN5 / Battery Pack Thermistor 0 - 2.30V No 54 6 General Purpose ADIN6 / Backup Voltage (LICELL) 0 - 2.30V / No / 55 1.50 - 3.50V -1.20V 56 7 General Purpose ADIN7 / UID / Die Temperature 0 - 2.30V / No / 57 0 - 2.55V / x0.9 / No 58 8 General Purpose ADIN8 0 - 2.30V No 59 9 General Purpose ADIN9 0 - 2.30V No 60 10 General Purpose ADIN10 0 - 2.30V No 61 11 General Purpose ADIN11 0 - 2.30V No 62 12 General Purpose TSX1 / Touchscreen X-plate 1 0 - 2.30V No 63 13 General Purpose TSX2 / Touchscreen X-plate 2 0 - 2.30V No 64 14 General Purpose TSY1 / Touchscreen Y-plate 1 0 - 2.30V No 65 15 General Purpose TSY2 / Touchscreen Y-plate 2 0 - 2.30V No 66 ======= =============================================== =============== ======= 67 68 - MC13892: 69 70 ======= =============================================== =============== ======= 71 Channel Signal Input Range Scaling 72 ======= =============================================== =============== ======= 73 0 Battery Voltage (BATT) 0 - 4.8V /2 74 1 Battery Current (BATT - BATTISNSCC) -60 - 60 mV x20 75 2 Application Supply (BPSNS) 0 - 4.8V /2 76 3 Charger Voltage (CHRGRAW) 0 - 12V / /5 77 0 - 20V /10 78 4 Charger Current (CHRGISNS-BPSNS) / -0.3 - 0.3V / x4 / 79 Touchscreen X-plate 1 0 - 2.4V No 80 5 General Purpose ADIN5 / Battery Pack Thermistor 0 - 2.4V No 81 6 General Purpose ADIN6 / Backup Voltage (LICELL) 0 - 2.4V / No 82 Backup Voltage (LICELL) 0 - 3.6V x2/3 83 7 General Purpose ADIN7 / UID / Die Temperature 0 - 2.4V / No / 84 0 - 4.8V /2 85 12 General Purpose TSX1 / Touchscreen X-plate 1 0 - 2.4V No 86 13 General Purpose TSX2 / Touchscreen X-plate 2 0 - 2.4V No 87 14 General Purpose TSY1 / Touchscreen Y-plate 1 0 - 2.4V No 88 15 General Purpose TSY2 / Touchscreen Y-plate 2 0 - 2.4V No 89 ======= =============================================== =============== =======
