Voltage-Tracking Controllers for
PowerPC, DSPs, and ASICs
General Description
The MAX5039/MAX5040 provide intelligent control to
power systems where two supply voltages need track-
ing. These cases include PowerPC ? , DSP, and ASIC
systems, which require a lower CORE voltage supply
and a higher I/O voltage supply.
The MAX5039/MAX5040 control the output voltage of
the CORE and I/O supplies during power-up, power-
down, and brownout situations. They ensure that the
two power supplies rise or fall at the same rate, limiting
the voltage difference between the CORE and I/O sup-
plies. This eliminates stresses on the processor. The
MAX5039/MAX5040 shut down both the CORE and I/O
supplies if either one is shorted or otherwise fails to
come up.
The MAX5040 provides a power-OK (POK) signal that
signals the processor if the CORE supply, the I/O sup-
ply, and the system bus supply (V CC ) are above their
respective specified levels. The MAX5039/MAX5040
are targeted for nominal bus V CC voltages from 4V to
5.5V. The MAX5039/MAX5040 work with CORE volt-
ages ranging from 800mV to about 3V (depending on
the gate-to-source turn-on threshold of the external N-

channel MOSFET) and I/O voltages ranging from
V CORE to 4V. The MAX5039/MAX5040 provide tracking
control of the I/O and CORE voltages using a single
external N-channel MOSFET connected across them.

PIN-PACKAGE

This MOSFET is not in series with the power paths and
does not dissipate any additional power during normal
system operation. The external MOSFET is only on for
brief periods during power-up/power-down cycling so a
low-cost, small-size MOSFET with a rating of 1/4th to
1/8th of the normal supply current is suitable.
The MAX5039/MAX5040 are offered in space-saving
8-pin μMAX and 10-pin μMAX packages, respectively.
