Overview
The A6810SLW-T is a bipolar latch driver manufactured by Allegro MicroSystems, designed for high-side switching applications. It features a 1:10 input-to-output ratio and provides ten independent outputs with a maximum current of 40mA per channel. The device operates on a supply voltage range of 3V to 5.5V and supports load voltages up to 60V. It utilizes non-inverting parallel or serial interfaces for control. The component is housed in a 20-SOIC surface-mount package and is rated for an operating temperature range from -20°C to +85°C.
Feature Summary
- Provides ten-channel high-side bipolar output capability for driving loads requiring latching control signals.
- Features a 1:10 input-to-output ratio allowing efficient control of multiple channels through minimal interface pins.
- Supports both parallel and serial interface configurations for flexible system integration.
Applications
- Bipolar stepper motor coil drive circuits
- High-side power switching for industrial loads
- Latching relay driver systems
Procurement Notes
Verify the specific suffix configuration against official datasheets, as variations may exist between tube and tape-and-reel packaging formats. Confirm RoHS compliance status, as historical data indicates discrepancies between different package types within the same base model number. Ensure the selected variant matches the required moisture sensitivity level and shipping format for your assembly process.
Selection Notes
Select this component when a high-side bipolar driver with a 1:10 gain ratio is required for controlling multiple loads efficiently. It is suitable for systems operating within a 3V to 5.5V logic domain and needing support for loads up to 60V. Consider the 20-SOIC package constraints and the specific interface requirements (parallel vs. serial) during PCB layout design.
Part Context
The A6810 belongs to Allegro's family of bipolar latch drivers, which are specialized integrated circuits for managing bidirectional current flow in inductive loads. These devices are distinct from standard MOSFET drivers by their internal latching mechanism, which maintains the output state without continuous signal input, reducing control line activity.
Replacement Considerations
Public records indicate that the A6810SLW variant is obsolete. Verify if the A6810SLWTR-T tape-and-reel version is available as a direct functional substitute or if a newer generation driver from the manufacturer is recommended for new designs.
