Overview
The TS5A23157TDGSRQ1 is an automotive-grade analog switch featuring two independent single-pole double-throw (SPDT) channels. Manufactured by Texas Instruments, it operates within a supply voltage range of 1.65 V to 5.5 V and is housed in a compact MSOP-10 package. The device exhibits a maximum on-resistance of 10 Ohms and supports a continuous DC switch current of 100 mA. Key electrical specifications include a maximum turn-on time of 5.7 ns and a maximum turn-off time of 3.8 ns. It is qualified under AEC-Q100 standards for automotive applications, ensuring reliability across a wide operating temperature range from -40°C to +105°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for enhanced reliability in vehicle environments.
- Dual-channel SPDT configuration providing flexible signal routing capabilities within a minimal footprint.
- Low power consumption characteristics suitable for battery-operated and energy-efficient systems.
Applications
- Automotive infotainment system signal switching
- Vehicle telematics unit input selection
- ADAS sensor signal path management
Procurement Notes
Verify the specific suffix 'TDGSRQ1' to confirm the extended temperature rating up to +105°C and automotive grade status. Ensure compatibility with the MSOP-10 package dimensions during PCB layout. Confirm that the design meets the AEC-Q100 requirements if deployed in safety-critical automotive modules. Cross-reference the datasheet for thermal dissipation limits in the selected enclosure.
Selection Notes
Select this component when dual SPDT switching is required in space-constrained automotive designs. Compare against the TS5A23157DGSRQ1 if a lower commercial temperature range (-40°C to +85°C) suffices for the application. Evaluate the 10 Ohm on-resistance against signal integrity requirements for high-frequency audio or video paths. Consider the 100 mA current limit for driving low-impedance loads directly.
Part Context
This part belongs to the TS5A23157 family of dual SPDT analog switches designed for portable and automotive electronics. The 'Q1' suffix denotes automotive catalog qualification, while 'T' indicates the extended industrial/automotive temperature range. It serves as a robust alternative to mechanical relays in modern electronic control units, offering faster switching speeds and higher durability.
Replacement Considerations
TS5A23157DGSRQ1 offers identical functionality but with a limited temperature range of -40°C to +85°C. TS5A623157DGSR provides similar performance without automotive qualification. Verify pinout compatibility before substitution to ensure direct replacement in existing assemblies.
