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 TechnologyвЂ™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 …
