LX7714 - 2.5A/1.25A RLCL Power Switches

Datasheet Summary

Description

The LX7714 is a quad power switch with line protection that is radiation-hardened-by-design and is used for spacecraft power distribution.

It provides a means to turn on and off four independent DC loads with continuous currents up to 2.5A.

Features

  • Four internal 2.5A or 1.25A rated power switches.
  • Power switches can be paralleled up to 10A.
  • Switches voltages to 46V.
  • Built-in fuse-like I²t current limiting.
  • Safe management of soft overload faults.
  • Automatic hiccup retry timer to clear faults.
  • Power Good and Fault status outputs.
  • Differential ON and OFF control inputs.
  • Low power switch voltage drop.
  • Over temperature shutdown.
  • Load current slew.

Preliminary LX7714 Quad 46V, 2.5A/1.25A RLCL Power Switches for Space Description The LX7714 is a quad power switch with line protection that is radiation-hardened-by-design and is used for spacecraft power distribution. It provides a means to turn on and off four independent DC loads with continuous currents up to 2.5A. The LX7714 comprises 4 independent protected power switch sections, each capable of driving a load up to 1.25A or 2.5A, depending on the version. The internal PMOS power switches use slew limiting when turned on and off to control power switching to capacitive loads, and to manage the switching off of inductive loads. A power switch automatically opens the circuit in the event of an overload condition.
