The converter has 1630(MC13783) resp. 12 (MC13892) channels which can be used in different modes. The31A/D converter has a resolution of 2.25mV.32 33Some channels can be used as General Purpose inputs or in a dedicated mode with34a chip internal scaling applied .35 36Currently the driver only supports the Application Supply channel (BP / BPSNS),37the General Purpose inputs and touchscreen.38 39See the following tables for the meaning of the different channels and their40chip internal scaling:41 42- MC13783:43 44======= =============================================== =============== =======45Channel Signal Input Range Scaling46======= =============================================== =============== =======470 Battery Voltage (BATT) 2.50 - 4.65V -2.40V481 Battery Current (BATT - BATTISNS) -50 - 50 mV x20492 Application Supply (BP) 2.50 - 4.65V -2.40V503 Charger Voltage (CHRGRAW) 0 - 10V / /551 0 - 20V /10524 Charger Current (CHRGISNSP-CHRGISNSN) -0.25 - 0.25V x4535 General Purpose ADIN5 / Battery Pack Thermistor 0 - 2.30V No546 General Purpose ADIN6 / Backup Voltage (LICELL) 0 - 2.30V / No /55 1.50 - 3.50V -1.20V567 General Purpose ADIN7 / UID / Die Temperature 0 - 2.30V / No /57 0 - 2.55V / x0.9 / No588 General Purpose ADIN8 0 - 2.30V No599 General Purpose ADIN9 0 - 2.30V No6010 General Purpose ADIN10 0 - 2.30V No6111 General Purpose ADIN11 0 - 2.30V No6212 General Purpose TSX1 / Touchscreen X-plate 1 0 - 2.30V No6313 General Purpose TSX2 / Touchscreen X-plate 2 0 - 2.30V No6414 General Purpose TSY1 / Touchscreen Y-plate 1 0 - 2.30V No6515 General Purpose TSY2 / Touchscreen Y-plate 2 0 - 2.30V No66======= =============================================== =============== =======67 68- MC13892:69 70======= =============================================== =============== =======71Channel Signal Input Range Scaling72======= =============================================== =============== =======730 Battery Voltage (BATT) 0 - 4.8V /2741 Battery Current (BATT - BATTISNSCC) -60 - 60 mV x20752 Application Supply (BPSNS) 0 - 4.8V /2763 Charger Voltage (CHRGRAW) 0 - 12V / /577 0 - 20V /10784 Charger Current (CHRGISNS-BPSNS) / -0.3 - 0.3V / x4 /79 Touchscreen X-plate 1 0 - 2.4V No805 General Purpose ADIN5 / Battery Pack Thermistor 0 - 2.4V No816 General Purpose ADIN6 / Backup Voltage (LICELL) 0 - 2.4V / No82 Backup Voltage (LICELL) 0 - 3.6V x2/3837 General Purpose ADIN7 / UID / Die Temperature 0 - 2.4V / No /84 0 - 4.8V /28512 General Purpose TSX1 / Touchscreen X-plate 1 0 - 2.4V No8613 General Purpose TSX2 / Touchscreen X-plate 2 0 - 2.4V No8714 General Purpose TSY1 / Touchscreen Y-plate 1 0 - 2.4V No8815 General Purpose TSY2 / Touchscreen Y-plate 2 0 - 2.4V No89======= =============================================== =============== =======90
