Product Details
The MAX5963 evaluation kit (EV kit) circuit demonstrates the dual hot-swap, current-limit/circuit-breaker, and ORing functions of the MAX5963 controller. The MAX5963 EV kit operates from a 7.5V to 40V DC source. The MAX5963 controls three separate dual n-channel MOSFETs to regulate load current from an input power supply providing up to 2A, and performs low-voltage-drop power-supply ORing for two independent outputs.
The MAX5963 EV kit features several jumpers to evaluate different configurations of the MAX5963. The output current-limit threshold, current-limit timeout period, circuit-breaker threshold and timeout period, ORing threshold, and fault-management features are programmable. Shutdown mode is controlled with on-board jumpers or user-supplied external logic signals. Active-low FAULT output signals are also provided for fault-condition monitoring. The EV kit circuit is configurable for evaluating the MAX5963 latchoff or autoretry function and late Vg protection feature.
