A6810SLW

Overview

The A6810SLW is a bipolar latch driver manufactured by Allegro MicroSystems, designed for power switching applications. It features a 1:10 input-to-output ratio with ten high-side outputs configured for bipolar operation. The device supports parallel and serial interfaces and accepts non-inverting inputs. It operates within a supply voltage range of 3V to 5.5V and handles load voltages up to 60V. Each output provides a maximum current of 40mA. The component is housed in a 20-SOIC package and functions reliably across an operating temperature range of -20°C to +85°C.

Feature Summary

• Provides ten independent high-side outputs for driving bipolar loads
• Supports both parallel and serial interface configurations for control flexibility
• Integrates internal protection mechanisms against thermal overload conditions

Applications

• Automotive lighting systems requiring high-side switching
• Industrial load distribution networks
• Consumer electronics power management circuits

Procurement Notes

Verify the specific suffix and revision level when sourcing replacements, as manufacturing updates may affect pin compatibility or packaging standards. Confirm RoHS compliance status explicitly, as this specific part number indicates non-compliance with current environmental directives. Ensure the supplier provides valid traceability documentation for automotive-grade components. Cross-reference the datasheet version to confirm interface timing requirements match your system design constraints before finalizing procurement orders.

Selection Notes

Select this component when a high channel count is required within a limited footprint. The 1:10 decoding capability reduces microcontroller I/O usage compared to individual drivers. Verify that the 40mA per output meets the load requirements without external amplification. Consider the 60V load voltage rating for automotive battery-connected applications. Evaluate the serial versus parallel interface needs based on available processor resources and speed requirements.
