Subsystem Components
Key component categories by subsystem
Power Management
- Buck-Boost Controllers — LM5176 for wide LiPo input
- LDO Regulators — TPS767 for dual-rail processors
- Battery Management — BQ series for charge control
- Current Sense Amplifiers — INA series for monitoring
- TVS Diodes — Littelfuse SP4020 for protection
Navigation & Sensing
- IMU Sensors — ICM-45686 for orientation
- Precision ADCs — ADS122U04 for sensor conditioning
- Barometric Pressure Sensors — BMP390
- Voltage References — REF195 for ADC accuracy
- Op-Amps — LM258 for signal conditioning
Design Requirements
Key engineering requirements
- Wide voltage input — LiPo 3.0V-4.2V per cell; multi-cell needs buck-boost
- Extended temperature — Military/ISR: -40°C to +85°C
- Low quiescent current — GPS and telemetry must minimize drain
- Radiation tolerance — High-altitude needs radiation-tolerant parts
- ECCN classification — Defense programs need export documentation
