Product Details

The EVAL-LT4200-AZ circuit board enables evaluation of two parallel LT4200 50 A hot swap E-fuses in a 100 A application. The LT4200 protects the backplane supply from glitches and sparks by controlling the inrush current during hot plug. During an output overload, the LT4200 shuts off after a delay to protect the internal power MOSFET and the backplane supply. The EVAL-LT4200-AZ includes resistive dividers for undervoltage and overvoltage protection and output power good. Turrets are provided for monitoring current, power good, fault status, and input and output voltages. Several test points allow probing of other circuit nodes. Design files for this circuit board are available at the Analog Devices, Inc. website.

Product Details

Demonstration circuit 3024A showcases the LT4200 50A hot swap E-fuse with guaranteed SOA. Included on the board are input voltage dividers for undervoltage and overvoltage protection, LEDs to indicate input voltage, output voltage, fault and power bad conditions, and jumpers to enable auto retry and to select circuit breaker delay. Turrets are provided for monitoring input voltage, output voltage, output status, and most of the pins on the LT4200.
