Product Details
The MAX5943A evaluation kit (EV kit) circuit demonstrates the hot-swap, current-limiting, and power-ORing functions of the MAX5943A. The MAX5943A EV kit is intended for 7.5V to 37V IEEE 1394™/FireWire® applications. The MAX5943A controls two n-channel MOSFETs to regulate load current from an input power supply and perform low-voltage-drop power-supply ORing. The MAX5943A EV kit can also be used to evaluate the MAX5943B/C/D/E versions (refer to the MAX5943 IC data sheet).
The MAX5943A EV kit features several jumpers to evaluate different configurations of the MAX5943A. The output current limit, current-limit timeout period, ORing threshold, and fault-management features are programmable. The undervoltage lockout threshold is configurable by installing external components. Shutdown mode can be controlled with an on-board switch or with an external logic signal. A active-low FAULT output signal is provided for fault condition monitoring.
