Overview
The A6812SLWTR-T is a power driver IC from Allegro MicroSystems featuring a 20-bit CMOS shift register with accompanying data latches and control circuitry. It provides bipolar sourcing outputs and operates within a supply voltage range of 3V to 5.5V, supporting a maximum load voltage of 60V. The device utilizes serial interface communication and is housed in a 28-SOIC package. It is designed for applications requiring high-density output control and is rated for an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrates a 20-bit CMOS shift register with data latches for sequential data handling
- Provides bipolar sourcing outputs for driving external loads
- Supports serial interface communication for efficient data input
Applications
- LED matrix drivers
- Industrial display systems
- Automotive interior lighting control
Procurement Notes
Verify the specific suffix 'SLWTR-T' against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Confirm end-of-life status as this component may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing serial clock and data lines in the target design.
Selection Notes
Select this component when a high-channel-count serial-to-parallel solution is required for sourcing applications. The 20-bit capacity reduces pin count compared to parallel alternatives. Verify that the bipolar sourcing capability aligns with the load requirements and that the SOIC package fits the thermal and spatial constraints of the PCB layout.
Part Context
This part belongs to the A6812 series of power drivers from Allegro MicroSystems, which are designed for high-performance shifting and latching applications. The series typically includes variants with different output configurations and packages, such as PLCC or DIP options, catering to diverse industrial and automotive needs.
Replacement Considerations
Check for direct substitutes like the A6812EEP-T or other A6812 family members. Verify pinout compatibility and electrical parameters before substitution. Note that some variants may have different package footprints or output types.
