Power Supply Sequencer with Power-up
System Monitoring
The X80200 power sequencer provides a flexible approach
for handling difficult system power-up conditions. The
X80200 includes control of up to three voltage supplies and
can be cascaded to control additional supplies. The device
contains independent undervoltage lockout for each
controlled voltage.
The three voltage control circuits allow sequencing for
primary, core, and I/O voltages. The core and I/O supplies
are linked together with a comparator or a timer allowing a
tight coupling between these two supplies. The sequencing
may be either voltage based or time based.
The X80200 contains separate charge pumps to control
external N-channel power FETs for each of the supplies. The
charge pumps provide the high gate control voltage
necessary for efficient operation of the FET switches.
The X80200 turns on the primary voltage to the system
when the voltage source is steady. This primary FET switch
turn-on can be delayed with an external RC circuit. For the
secondary voltage sources, the device has a built-in “core-
up-first and core-down-last” sequencing logic which is ideal
for high performance processors, DSPs and ASICs.
The serial bus can be used to monitor the status or turn off
each of the external power switches. The X80200 has 3
slave address bits that allow up to 8 devices to be connected
to the same bus.
