Overview

Product Details

Demonstration circuit 1354B is a positive high voltage hot swap controller featuring either the LT®1641-1, LT1641-2, LT4256-1, or LT4256-2.

The board facilitates measurement of transient conditions, steady state operation with different loads, and fault conditions. The Controller responds to fault conditions such as input undervoltage(UV), output power good (PWRGD) fault, and overcurrent and response can be verified by the output voltage (VOUT) LED state and PWRGD pin signal. The LT1641-1 and LT4256-1 latch off if MOSFET shuts off under overcurrent condition, while LT1641-2 and LT4256-2 automatically restart after time-out delay.

The DC1354B contains one hot swap controller, power MOSFET, current sense resistor, enable circuit, input voltage clamp, gate protection circuit, resistive output voltage divider for feedback signal, and three LEDs to indicate the presence of input and output voltages and power good condition.
