Dual-/Triple-Voltage, Power-Supply
Sequencers/Supervisors
General Description
The MAX6880–MAX6883 dual-/triple-voltage monitors
are designed to sequence power supplies during
power-up condition. When all of the voltages exceed
their respective thresholds, these devices turn on volt-
ages to the system sequentially, enhancing n-channel
MOSFETs used as switches. The time between each
sequenced voltage is determined by an external
capacitor, thus allowing flexibility in delay timing. The
MAX6880/MAX6881 sequence three voltages and the
MAX6882/MAX6883 sequence two voltages.
These devices initially monitor all of the voltages and
when all of them are within their tolerances, the inter-
nal charge pumps enhance external n-channel
MOSFETs in a sequential manner to apply the volt-
ages to the system. Internal charge pumps drive the
gate voltages 5V above the respective input voltage
thereby ensuring the MOSFETs are fully enhanced to
reduce the on-resistance.
The MAX6880–MAX6883 feature capacitor-adjustable
slew-rate control to provide controlled turn-on charac-

teristics. After all of the voltages reach 92.5% of their
final value, a power-good output (MAX6880/MAX6882)
signal is active. The power-good output (PG/ RST ) can
be delayed with an external capacitor to create a
power-on reset delay. After the initial power-up phase,
the MAX6880–MAX6883 continue to monitor the volt-
ages. If any of the voltages falls below its threshold, the

MOSFETs are quickly turned off and the voltages are
tracked down together. An internal 100 ? pulldown
resistor ensures that the capacitance at the MOSFET’s
source is discharged quickly. The power-good output
goes low to provide a system reset.
