In addition to these Device powered by the highest of VPx, VH for improved functions, the ADM1063-EP integrates a 12-bit ADC that can redundancy be used to accurately read back up to 12 separate voltages. User EEPROM: 256 bytes The device also provides up to 10 programmable inputs for Industry-standard, 2-wire bus interface (SMBus) monitoring undervoltage faults, overvoltage faults, or out-of- Guaranteed PDO low with VH, VPx = 1.2 V window faults on up to 10 supplies. In addition, 10 programmable Available in 40-lead, 6 mm 6 mm LFCSP package outputs can be used as logic enables. Six of these programmable outputs can provide up to a 12 V output for driving the gate of For more information about the ADM1063 register map, an N-FET that can be placed in the path of a supply. refer to the AN-698 Application Note at www.analog.com.
