ARPS10x0A5: Introducing the most compact radiation-hardened smart power switch for spacecraft

About

Introducing the Apogee Semiconductor ARPS10x0A5, a radiation-hardened power switch family from Apogee engineered to bring deterministic protection, fault containment, and continuous health telemetry to spacecraft and other mission-critical power architectures.
We’ll cover how it supports fault detection, isolation, recovery, current telemetry, overcurrent protection, thermal shutdown, and scalable PDU architectures.

Features:
- Compact
- 28V bus down to 3.3V
- Dual enable
- Programmable overcurrent protection
- Thermal protection
- Break-before-make functionality
- Programmable in-rush control
- True parallel operation for higher currents
- Current telemetry
- Enabling smart PDU, pairing with APIO16
- Radiation performance
- Design support: Models, EVMs,
- Product Grades

Presenter

David Grant

Lead Architect

David has 40 years of professional electronic engineering experience. Before joining Apogee, he worked at Texas Instruments, where he designed and led designs for LDOs, PCMCIA switches, POL buck controllers, integrated FET buck converters, integrated IF transceivers, and a reconfigurable, mixed-signal power control IC platform. As lead architect at Apogee Semiconductor, he has developed much of the foundational radiation resilience architecture used in Apogee’s portfolio including the Platinum Award-winning AxIO16 GPIO Expander. David has 36 issued US patents. He holds a Bachelor of Science degree from the University of Glasgow in Scotland, UK.
