The Texas Instrument TPS7H2201-SP is a single channel load switch radiation hardened and suitable for space satellite power management and distribution.

With a programmable slew rate, configurable rise time is provided by the component to minimize the reverse current protection and inrush current.

The component features a P-Channel MOSFET capable operating over a range of input voltage. An on and off input (EN) controls the switch that interfaces directly with the low-voltage control signals.

The integrated thermal pad with the ceramic package of the component allows high power dissipation.


  • Space satellite power management and distribution
  • Radiation hardened and tolerant power tree applications
  • Available in military (–55°C to 125°C) temperature range
