The EV kit demonstrates Configured for 5A Load-Current Threshold the programmable overpower monitoring feature with Reconfigurable Overpower Thresholds manual or microcontroller reset options of the MAX4211E. The MAX4211E controls an external p-channel high-side Immune to Power-Up Capacitive Load Spikes power MOSFET to provide overpower fault protection. Configurable Reset (Manual or Microcontroller) The MAX4211E EV kits circuit overpower threshold is configured for 100W with a maximum input voltage of Surface-Mount Components 20V and up to 5A of load current. This makes it suitable Fully Assembled and Tested for circuit-breaker applications in notebooks and other portable power systems. The EV kit may be reconfig- Evaluates MAX4211A, MAX4211B, MAX4211C, ured for other power thresholds with a maximum load MAX4211D, or MAX4211F (IC Replacement current of up to 10A. Required) The EV kit can also be used to evaluate other versions of the MAX4211 power-monitoring ICs.
