Digital Potentiometers datasheet and documents for CAT5269YI-50T-QJ
Digital Potentiometers Overview
The CAT5269YI-50T-QJ is a dual-channel digital potentiometer IC manufactured by onsemi. It features two independent potentiometers, each with 256 taps and a resistance of 50 kOhms. The device utilizes a non-volatile memory architecture to retain wiper settings without power. It operates within a supply voltage range of 2.5 V to 6 V and supports a 2-wire I2C serial interface for control. The component is designed for automotive applications, indicated by the 'QJ' suffix, and functions across an extended temperature range from -40°C to +125°C.
Digital Potentiometers Feature Summary
- Dual-channel configuration with independent wiper control
- Non-volatile memory retains position after power loss
- Automotive-grade reliability and qualification
- Serial I2C interface for simplified system integration
Digital Potentiometers Applications
- Automotive lighting brightness control
- Vehicle seat position adjustment systems
- HVAC airflow regulation in automobiles
- Audio volume or tone control in infotainment units
Digital Potentiometers Procurement Notes
Verify the specific suffix 'QJ' confirms automotive grade qualification and extended temperature range capabilities. Confirm that the '50' designation corresponds to the 50 kOhm resistance value required for the circuit design. Ensure the SOIC-24 package dimensions match the PCB footprint constraints. Cross-reference the datasheet for any specific ordering restrictions or end-of-life notifications associated with this part number.
Digital Potentiometers Selection Notes
Select this component when dual-channel precision control is required in space-constrained automotive environments. The non-volatile feature eliminates the need for initialization routines at startup. Compare against single-channel alternatives if only one potentiometer is needed. Consider the 256-tap resolution for smooth adjustment requirements. Verify compatibility with the system's I2C bus speed and voltage levels before finalizing the selection.
Digital Potentiometers Part Context
This part belongs to the CAT5269 family of digital potentiometers. It shares architectural similarities with other onsemi digital pots but is distinct due to its dual-channel layout and automotive qualification. It serves as a solid-state replacement for mechanical potentiometers in critical vehicle systems where reliability and size are paramount.
Digital Potentiometers Replacement Considerations
CAT5269WI-50-T1 is a commercial grade equivalent with similar electrical specifications but lacks automotive qualification. CAT5269YI-50-QJ appears to be a variant with identical core functionality. Verify pinout compatibility and software register mapping before substitution.
