With a proven legacy of 55+ years in the Space market and supporting countless Space programs both domestically and internationally, TI is a trusted partner. We focus on radiation performance and best-in-class SWaP (Size, Weight, and Power) to enable leading-edge designs.
2 The breadth of TI s Space portfolio provides a full signal-chain solution. The portfolio includes the smallest RHA point-of-load power solutions, fast discrete SerDes, and some of the world s highest performance data s Space Products include MIL-PRF-38535 QML Class V and RHA components. These devices are typically supported with Total Ionizing Dose (TID) and Single Event Effects (SEE) test reports to address poten-tial product degradation in a Space environment. The test results for these devices are available at Applications Satellite bus/platform General payload Communications payload Imaging payload Data processing and storage (solid-state recorder) Telemetry sensors Inertial navigation (IMU/INS)

4 In Space , these particles generally have so much energy that they easily ionize atoms, freeing negatively-charged electrons and leaving the positively-charged atoms. In electronic devices, this ionization process creates excess charge, which can produce both tran-sient and lasting Ionizing DoseThe most common radiation require-ment in the aerospace design commu-nity is Total Ionizing Dose (TID), also known as total dose. Total-dose effects are caused when electrons and protons create excess charge in the dielectric layers used for insulation in electronic devices. Total-dose effects are cumu-lative and require chronic exposure to numerous radiation events before device degradation becomes obvious.
5 Electronics in a satellite or spacecraft thus accumulate TID damage over time as they operate under continuous levels of radiation . While electrons are mobile in insulators, the holes (positively-charged atoms) must move by breaking bonds and can become trapped in defects. The result of this accumulated positive charge in a device s insulators leads to degradation and/or device failure. The oxide charge buildup affects the current-voltage characteristics of transistors used in semiconductor circuits. Proper opera-tion of a transistor relies on the ability to switch it from a low-conductance (off) state to a high-conductance (on) state as the gate voltage passes through a threshold.
6 Extended expo-sure to TID radiation can shift the threshold voltages, making transistors easier or harder to switch. radiation may also increase the leakage current, causing the on and off states of the transistors to become less distinguish-able. Either effect can ultimately cause circuit failure. For our Space Products , these effects have been characterized and summarized in our TID radiation Reports at EffectsThe second and perhaps the most critical radiation effect to consider is Single-Event Effects (SEEs). SEEs actually include multiple different failure modes; the one commonality is that all of the failure modes are created by the passage of a single ionizing particle (single-event).
7 SEE failures in digital and analog devices are usually soft, meaning that the data or node voltage is affected but the device is not perma-nently damaged. These failures include the Single-Event Transient (SET), the Single-Event Upset (SEU), the Single-Event Functional Interrupt (SEFI), and possibly the Single-Event Latch-up (SEL), which may be destructive. Power devices are dominated by hard failure modes such as the Single-Event Burn-Out (SEB) and Single-Event Gate Rupture (SEGR), but can also suffer from soft mechanism like SET in the output or a SEFI in the PGOOD signal. The functional failures caused by SEE are evaluated in Space devices using the heavy ion beam provided by a cyclotron facility.
8 These effects on our Space Products are captured in our Single-Event Effects radiation reports at and High-Reliability Design ToolsTI s High-Reliability portfolio offers a comprehensive suite of design tools to serve your simulation needs. You canfind support for transient and AC-Spice simulations, solution size estimation and thermal modeling via TI s WEBENCH simulation tools, and dgital I/O support via IBIS models. Our Spice models are thoroughly correlated to our Cadence design database, laboratory test benches, and mathematical represen-tations. A variety of sources are also used for IBIS model creation. These range from simulation tools in the IC design flow to third-party empirical testing.
