The MAX5904-MAX5909 dual hot-swap controllers provide complete protection for dual-supply systems. These devices hot swap two supplies ranging from +1V to +13.2V, provided one supply is at or above 2.7V, allowing the safe insertion and removal of circuit cards into live backplanes.

The discharged filter capacitors of the circuit card provide low impedance to the live backplane. High inrush currents from the backplane to the circuit card can burn up connectors and components, or momentarily collapse the backplane power supply leading to a system reset. The MAX5904 family of hot-swap controllers prevents such problems by gradually ramping up the output voltage and regulating the current to a preset limit when the board is plugged in, allowing the system to stabilize safely. After the startup cycle is completed, two on-chip comparators provide VariableSpeed/BiLevel™ protection against short-circuit and overcurrent faults, as well as immunity against system noise and load transients. In the event of a fault condition, the load is disconnected. The MAX5905/MAX5907/MAX5909 must be unlatched after a fault, and the MAX5904/MAX5906/MAX5908 automatically restart after a fault.

The MAX5904 family offers a variety of options to reduce component count and design time. All devices integrate an on-board charge pump to drive the gates of low-cost, external N-channel MOSFETs. The devices offer integrated features like startup current regulation and current glitch protection to eliminate external timing resistors and capacitors. The MAX5906-MAX5909 provide an open-drain status output, an adjustable startup timer, an adjustable current limit, an uncommitted comparator, and output undervoltage/overvoltage monitoring.

The MAX5904/MAX5905 are available in 8-pin SO packages. The MAX5906-MAX5909 are available in space-saving 16-pin QSOP packages.

Product Detail

The MAX5908 evaluation kit (EV kit) is a fully assembled and tested surface-mount, dual hot-swap controller circuit board that provides current-limiting and Variable Speed/Bilevel™ fault protection. The circuit uses a MAX5908 IC in a 16-pin QSOP package and is configurable for an input range of +1.0V to +13.2V.

The EV kit is configured for +5V and +1.8V inputs. Both inputs are configured for up to 10A of output current. The MAX5908 controls two N-channel MOSFETs and provides current regulation during startup for both inputs. Several configurations allow the MAX5908 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 of the MAX5908.

The EV kit features several configurations for the startup timer setting, current limit, and output-voltage monitoring. The EV kit also provides power-on sequencing for the outputs. The EV kit can also be used to evaluate a MAX5906, MAX5907, or MAX5909 after replacing the MAX5908 with the desired IC. Additionally, the EV kit can be reconfigured to emulate a dual MAX5904 or MAX5905 hot-swap controller design.
