  I2C Programmable Multichannel Voltage Supervisors with
  EEPROM
  Michael Petersen The LTC2933 and LTC2936 are 6-channel, I2C/SMBus programmable voltage
  supervisors with EEPROM. Table 1 shows Linear Technology’s broad line
  of programmable voltage supervisors and Power System Managers. The
  LTC2933 and LTC2936 are well suited for multirail systems that require accurate
  power supply overvoltage (OV) and undervoltage (UV) detection.
  UNMATCHED VERSATILITY Comparator output mapping to
  dedicated comparator output pins
  (LTC2936 only) The following features can be configured,
  read, modified, and stored in the onboard
  EEPROM via the I2C/SMBus interface: I2C/SMBus write protection Two voltage thresholds for each of the
  six inputs First fault snapshot
  The threshold settings for each channel
  are programmable over multiple voltage
  ranges and feature 256 settings per range
  (see Tables 2 and 3). Programmability
  eliminates the need to qualify, source or
  stock unique parts for different threshold
  voltages or other feature combinations. Comparator polarity and mapping to
  GPIO pins GPIO mode, polarity, and delay GPI mode, polarity, and mapping to
  GPIO pins A snapshot of the first fault to occur after
  power-up is stored in the EEPROM, which …
