EVAL-LTC4286-A1Z

EVAL-LTC4286-A1Z is an evaluation board for evaluating LTC4286 high power positive hot-swap controller with power monitor via PMBus. The LTC4286 is an integrated solution for hot-swap applications allowing a board to be safely inserted and removed from a live backplane. The circuit breaker timer protects against metal-oxide semiconductor field-effect transistor (MOSFET) overheating, enabling reliable protection against overstress. The SMBus 3.1 interface, PMBus command structure, and on-board analogue-to-digital converter (ADC) with selectable averaging and speed allow monitoring of board current, voltage, power, temperature, and fault status. The LTC4286 has additional features to respond to input undervoltage (UV) and overvoltage (OV): interrupts the host when a fault occurs, notifies when output power is good, detects insertion of a board, and auto-reboot after a programmable delay following a host commanded turn off.

• Wide operating voltage range from 8.5V to 80V
• Monitors currents, voltages, and power with ADC
• Adjustable, 5% accurate current limit: 6mV to 20mV
• Current foldback limits MOSFET power dissipation for overstress protection
• Monitors VGS and VDS for MOSFET health
• Peak detect registers for current, voltage, and power
• Reports input or output power
• Remote temperature sensing with programmable warning and shutdown thresholds
