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 active-low RESET output signals to indicate an undervoltage condition, or when active-low SHDN or active-low FAULT signals are pulled low. Additionally, dedicated active-low 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.
