    nn 16-Pin 5mm Г— 4mm DFN and SSOP Packages The LTCВ®2933 is an EEPROM configurable voltage supervisor which can simultaneously monitor up to six power
    supply voltage inputs. Each voltage detector offers I2C
    programmable over/undervoltage thresholds in various
    ranges and increments. nn Two general purpose inputs (GPI) can be configured as
    programmable manual reset (MR), UV disable (UVDIS),
    margin (MARG) or auxiliary comparator (AUXC) inputs.
    Three general purpose pins (GPIO) can be configured for
    input or output operation. When configured as an input, a ...

    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 ...
