FUNCTION
Optional Supply Voltage Input. Connect V CC to an alternate (i.e., always-on) supply if desired. V CC
supports operation/communication when the monitored supplies are not powered or are below the
minimum required operating voltage. In a master/slave application, connect all V CC pins to a common
supply line.
Ground
Internal Analog Bypass. Bypass ABP with a 1μF capacitor to GND. ABP maintains the device supply
voltage during rapid power-down conditions.
Tracking Enable Input. TRKEN must be higher than 1.285V to enable voltage tracking power-up
operation. When TRKEN falls below 1.25V (3% hysteresis), OUT_ tracks down. Connect TRKEN to an
external resistor-divider network to set the desired monitor threshold. Connect TRKEN to ABP if not
used.
Selectable Tracking Synchronization Output/Input. SYNCH allows multiple MAX6876 devices to
control tracking of multiple power supplies (up to 16 voltages on the same I 2 C bus). One device is
programmed as SYNCH master and all other devices are programmed as slaves. SYNCH on the
master outputs the common ramp voltage to which all OUT_ voltages are tracked (with active control
loops). SYNCH of the slave devices is input for the ramp control voltage (no internal ramp is
generated in the slaves) (see the SYNCH section). Connect SYNCH to other SYNCH pins only.
Active-Low, Open-Drain Synchronization Hold Output/Input. HOLD communicates synchronization
status between master/slave devices in multiple MAX6876 applications. The HOLD output remains
asserted while selected tracking IN_ inputs are below their selected thresholds (the slave device can
delay tracking start until its inputs are at their required stable voltage levels) or held low by the master
when it is counting the autoretry time after a detected fault condition (see the Synchronization Hold
Output ( HOLD ) section). Slave device SYNCH are inputs for the ramp control voltage.
