MAX16050 Evaluation Kit

General Description

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.

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.

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.
