Product Details

The MAX6877 evaluation kit (EV kit) is a complete, fully assembled and tested multivoltage power tracker/sequencer/supervisor controller circuit that demonstrates the capability of the MAX6877 controller. The MAX6877 ensures controlled voltage tracking or sequencing of up to three power-supply outputs during power-up, and controlled voltage during power-down. Voltage tracking ensures that all output voltages of the supplies rise or fall at the same rate while voltage sequencing turns on the outputs in order once the input voltages reach stability. The EV kit circuit features active-low FAULT and PG/active-low RST output signals to indicate fault and power-good conditions, respectively. The circuit's timing parameters and voltage thresholds are reconfigurable. The EV kit board is designed to handle up to 10A per channel.

Applications

  • Multivoltage Systems
  • Networking Systems
  • Servers/Workstations
  • Storage Equipment
  • Telecom
