The MAX16046A/MAX16048A EEPROM-configurable system managers monitor, sequence, track, and margin multiple system voltages. The MAX16046A manages up to twelve system voltages simultaneously, and the MAX16048A 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 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 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 (MAX16046A) or up to eight (MAX16048A) 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 MAX16046A/MAX16048A 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 MAX16046A/MAX16048A 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 (active-low MR), or as margin control inputs.
The MAX16046A/MAX16048A feature two methods of fault management for recording information during system shutdown 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 MAX16046A/MAX16048A. These devices are offered in a 56-pin, 8mm x 8mm TQFN package or a 64-pin, 10mm x 10mm TQFP package and are fully specified from -40°C to +125°C.
