MAX5944EVKIT：Evaluation Kit for the MAX5944
The MAX5944 evaluation kit (EV kit) circuit demonstrates the multiple functions of the MAX5944 IC. The MAX5944 IC is a two-channel controller that performs hot-swapping, power-supply ORing, and current-limiting functions for FireWire® applications. The MAX5944 controls n-channel MOSFETs to regulate load current from two input power supplies and performs low-voltage-drop power-supply ORing. The output current limit and input undervoltage-lockout thresholds are configurable.
The MAX5944 EV kit is intended for 7.5V to 37V FireWire power-supply applications. The current-limit threshold is configured to 1.6A per channel. Shutdown mode can be controlled with an on-board jumper. A fault output for each channel is provided for circuit monitoring.
