Overview
19-1050; Rev 0; 10/07 12-Channel/8-Channel EEPROM-Programmable System Managers with Nonvolatile Fault Registers General Description The MAX16046/MAX16048 EEPROM-configurable system managers monitor, sequence, track, and margin multiple system voltages.
The MAX16046 manages up to twelve system voltages simultaneously, and the MAX16048 manages up to eight supply voltages.
These devices integrate an analog-to-digital converter (ADC) for monitoring supply voltages, digital-to-analog converters (DAC) for adjusting www.

com supply voltages, and configurable outputs for sequencing and tracking supplies (during power-up and powerdown).
Nonvolatile EEPROM registers are configurable for storing upper and lower voltage limits, setting timing and sequencing requirements, and for storing critical fault data for readback following failures.
An internal 1% accurate 10-bit ADC measures each input and compares the result to one upper, one lower, and one selectable upper or lower limit.
A fault signal asserts when a monitored voltage falls outside the set limits.
Up to three independent fault output signals are configurable to assert under various fault conditions.
The integrated sequencer/tracker allows precise control over the power-up and power-down order of up to twelve (MAX16046) or up to eight (MAX16048) power supplies.
Four channels (EN_OUT1–EN_OUT4) support closedloop tracking using external series MOSFETs.
Six outputs (EN_OUT1–EN_OUT6) are configurable with chargepump outputs to directly drive MOSFETs without closedloop tracking.
The MAX16046/MAX16048 include twelve/eight integrated 8-bit DAC outputs for margining power supplies when connected to the trim input of a point-of-load (POL) module.
The MAX16046/MAX16048 include six programmable general-purpose inputs/outputs (GPIOs).
GPIOs are EEPROM configurable as dedicated fault outputs, as a watchdog input or output (WDI/WDO), as a manual reset (MR), or for margin control inputs.
The MAX16046/MAX16048 feature two ...
