Overview
The A6810ELWTR-T is a bipolar latching driver manufactured by Allegro MicroSystems, designed for high-side power switching applications. It features a 1:10 input-to-output ratio and delivers a maximum output current of 40mA per channel. The device operates with a supply voltage range of 3V to 5.5V and supports load voltages up to 60V. It utilizes parallel and serial interfaces for control. The component is housed in a 20-SOIC package (7.50mm wide) and is rated for an operating temperature range of -40°C to +85°C.
Feature Summary
- Bipolar latching driver architecture for precise magnetic state retention
- High-side output configuration supporting loads up to 60V
- Integrated 1:10 gain stage providing 40mA drive capability
- Dual interface support for both parallel and serial communication
Applications
- Industrial motor control systems requiring latched states
- Automotive power distribution units
- General-purpose high-side load switching in embedded electronics
Procurement Notes
Verify the specific suffix ELWTR-T against official datasheets to confirm RoHS compliance status, as variations within the A6810 family may differ. Confirm that the 20-SOIC tape-and-reel packaging matches your automated assembly requirements. Cross-reference the manufacturer's latest product change notices regarding moisture sensitivity levels before finalizing procurement plans.
Selection Notes
Select this component when a bipolar latching response is required rather than a standard logic gate function. Ensure the system design accommodates the 1:10 gain ratio and 40mA output limit. Verify that the 3V to 5.5V supply range aligns with the host controller logic levels. Consider the 20-SOIC footprint constraints during PCB layout planning.
Part Context
This part belongs to the A6810 series of bipolar latching drivers from Allegro MicroSystems. The series provides versatile solutions for controlling external power switches using magnetic inputs. Variations in the suffix indicate differences in packaging, such as tube versus reel, and compliance standards like RoHS.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Allegro MicroSystems directly for qualified alternatives or pin-compatible replacements.
