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.

+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.
