说明 The MAX4273 evaluation kit (EV kit) is a fully assembled and tested surface-mount hot-swap controller circuit board that provides current-limiting and DualSpeed/Bi-Level fault protection. The circuit uses a MAX4273 IC in a 16-pin QSOP package and is configured for a +2.7V to +13.2V input voltage range.
The MAX4273 controls the N-channel MOSFET and provides current regulation during startup. Several configurations allow the MAX4273 IC’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 provided by the MAX4273 IC.
The EV kit features a power-on reset (POR) circuit. Several configurations for autoretry, glitch filters, auxiliary VCC power, and gate drive speed are provided. The EV kit can also be reconfigured to emulate the MAX4271 and MAX4272 hot-swap controllers.
