Product Details

The MAX5927 evaluation kit (EV kit) is a fully assembled and tested surface-mount quad hot-swap controller/power-sequencer/voltage-tracker circuit board, which provides current limiting and VariableSpeed/BiLevel™ fault protection on all four channels. The circuit uses the MAX5927 in a 32-pin thin QFN package and is configurable for a 1.0V to 13.2V input range. The MAX5927 features a configurable latch/autoretry fault mode, circuit-breaker function, and programmable undervoltage lockout (UVLO).

The EV kit is configured to demonstrate four separate input voltages: 5V, 3.3V, 2.5V, and 1.8V. The 5V input is configured for 0.5A of output current, while the 3.3V input is configured for 1.5A of output current. The 2.5V and 1.8V inputs are each configured for 5A of output current. The MAX5927 controls four n-channel power MOSFETs and provides current regulation during startup for all four inputs. Several configurations allow the MAX5927's unique current regulation architecture to be tailored to the application. The current limiting and short-circuit protection features are configurable and demonstrate the various features of the MAX5927.

The EV kit has several configurations for the startup timer setting, current limit, and voltage-tracking/powersequencing/independent modes of operation. The EV kit also provides independent turn-on delays for the four outputs, independent on/off control, and independent status reports of all four channels. The MAX5927 EV kit can also be reconfigured to emulate a MAX5929 (quad hot swap), MAX5930 (triple hot swap), or MAX5931 (triple hot swap) design.
