MAX16050 Evaluation Kit
Evluates:/MAX6051
General Description
Features
The MAX16050 evaluation kit (EV kit) is a complete, fully
assembled and tested multivoltage sequencer circuit that
demonstrates the capability of the 4-channel MAX16050
and 5-channel MAX16051 sequencing ICs. The
MAX16050 EV kit monitors up to nine DC-DC converter
outputs and ensures proper power-up and power-down
conditions for systems requiring voltage sequencing.
♦ Quick Demo Mode Evaluation Without DC-DC
Converters
♦ Monitors and Sequences Up to Nine DC-DC
Converter Outputs
♦ Reverse-Sequencing Operation
♦ Configurable Sequencing Order (MAX16050 Only)
The EV kit features RESET output signals to indicate an
undervoltage condition, or when SHDN or FAULT sig-
nals are pulled low. Additionally, dedicated OV_OUT
outputs indicate an overvoltage fault when any of the
EV kit’s inputs go above the overvoltage threshold. The
EV kit is capable of evaluating the MAX16050 and
MAX16051 individually. The EV kit can be configured
for daisy chaining these two devices together, which
enables the user to sequence and monitor up to nine
voltages across both devices. The MAX16050 EV kit
also provides PCB pads for low-current MOSFETs that
are controlled using the MAX16050 and MAX16051
charge-pump outputs.
♦ Daisy-Chaining Operation of the MAX16050 and
MAX16051
♦ Overvoltage and Power-Good Monitoring
♦ Fully Assembled and Tested

+Denotes lead-free and RoHS compliant.
The MAX16050 EV kit utilizes two power supplies, one
for each IC. Each power supply can range from 2.7V to
13.2V, allowing the user to operate directly from an
intermediate bus voltage. The MAX16050 EV kit also
requires an additional 2.2V to 5.5V power supply for the
pullup resistors’ open-drain logic outputs.
