Discover a space-qualified single-chip solution that integrates all the functions of a solid-state protection (SSP) system
Check out our on-demand webinar for an inside look at a pioneering new solution for power management in space applications.
The RHRPMICL1A is an innovative radiation-hardened (rad-hard), programmable integrated current limiter (ICL) that prevents power surges and overloads from damaging electronic equipment operated in space. It can be used as a universal solution to protect power supplies from anomalous external current demand (e.g. in cases where the load enters latch-up conditions) or to protect/replace conventional fuses, and can also be used to control redundant loads.
The device features three user-configurable operating modes (re-triggerable, latched, foldback), with different behaviors for overload or short-circuit events.
All key parameters of the RHRPMICL1A are configurable, including current limit, trip-off and recovery times, and undervoltage protection, making it ideal for a wide range of applications. Thanks to its floating ground, it can even be used on power buses with supply voltages higher than its specification maximum of 52 V.
