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 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.
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 (MAX16047) or up to eight (MAX16049) power supplies. Four channels (EN_OUT1–EN_OUT4) support closed-loop tracking using external series MOSFETs. Six outputs (EN_OUT1–EN_OUT6) are configurable with charge-pump outputs to directly drive MOSFETs without closed-loop tracking.
The MAX16047/MAX16049 include six programmable general-purpose inputs/outputs (GPIOs). In addition to serving as EEPROM-configurable I/O pins, the GPIOs are also configurable as dedicated fault outputs, as a watchdog input or output (WDI/WDO), or as a manual reset (active-low MR).
The MAX16047/MAX16049 feature two methods of fault management for recording information during critical fault events. The fault logger records a failure in the internal EEPROM and sets a lock bit protecting the stored fault data from accidental erasure.
An I²C/SMBus™-compatible or a JTAG serial interface configures the MAX16047/MAX16049. These devices are offered in a 56-pin 8mm x 8mm TQFN package and are fully specified from -40°C to +85°C.
