19-1869; Rev 0; 11/07 12-Channel/8-Channel EEPROM-Programmable System Managers with Nonvolatile Fault Registers General Description The MAX16047/MAX16049 EEPROM-configurable system managers monitor, sequence, and track multiple system voltages. The MAX16047 manages up to twelve system voltages simultaneously, and the MAX16049 manages up to eight supply voltages. These devices integrate an analog-to-digital converter (ADC) for monitoring supply voltages, and configurable outputs for sequencing and www.DataSheet4U.com tracking supplies (during power-up and power-down). Nonvolatile EEPROM registers are configurable for storing upper and lower voltage limits, setting timing and sequencing requirements, and for storing critical fault data for read back following failures.
