Overview
The A6801SEP-T is a bipolar latched driver IC manufactured by Allegro MicroSystems, housed in a 28-PLCC package. It features eight low-side outputs with a 1:1 input-to-output ratio and supports a maximum load voltage of 50V. The device operates on a supply voltage range of 3V to 5.5V and delivers a maximum output current of 600mA per channel. It utilizes parallel gate pulse interfaces with non-inverting inputs. The component is rated for an ambient operating temperature range from -20°C to +85°C.
Feature Summary
- Integrates eight independent low-side bipolar latched drivers within a single integrated circuit.
- Supports parallel gate pulse interface control with non-inverting logic inputs.
- Designed for robust operation under high load voltage conditions up to 50V.
- Provides reliable performance across standard industrial temperature ranges.
Applications
- Bipolar stepper motor driving systems
- General-purpose power switching applications
- Industrial control circuits requiring multiple low-side outputs
Procurement Notes
Verify the specific suffix SEP-T against official manufacturer documentation to confirm the 28-pin PLCC package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for obsolescence notices as this part may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing PCB footprints for the J-lead PLCC form factor.
Selection Notes
Select this component when a multi-channel low-side driver with latching functionality is required. The 28-PLCC package offers a compact solution for designs needing eight isolated outputs. Consider the 600mA current limit and 50V voltage rating to ensure adequate headroom for the intended load. Verify that the parallel gate pulse interface aligns with the system's control logic architecture.
Part Context
The A6801 series represents Allegro MicroSystems' portfolio of bipolar latched drivers designed for versatile power switching tasks. These devices are engineered to simplify the control of bipolar loads such as stepper motors or solenoids. The SEP-T variant specifically denotes the plastic leaded chip carrier package option, providing a distinct physical footprint compared to SOIC or DIP alternatives within the same functional family.
Replacement Considerations
Publicly confirmed substitute part numbers for the A6801SEP-T are not available in the provided source material. Consult Allegro MicroSystems technical support for current cross-reference data or alternative components with matching pinouts and electrical specifications.
