AN44065A-VF

Overview

The AN44065A-VF is a bipolar stepper motor driver IC manufactured by Panasonic Industry. It operates within a supply voltage range of 10 V to 34 V and delivers an output current of 800 mA. The device utilizes a power MOSFET technology and features a parallel interface for control signals. It is housed in a 32-SSOP package with a width of 6.10 mm. The component supports full, half, eighth, and sixteenth step resolutions. It functions as a fully integrated driver including both control and power stages. The operating junction temperature range extends from -20°C to 120°C.

Feature Summary

• Integrated power MOSFET output stage for high-current drive capability
• Supports multiple stepping resolutions including full, half, eighth, and sixteenth steps
• Parallel interface design for straightforward digital control integration

Applications

• General purpose stepper motor control systems
• Wearable technology components requiring compact motor drivers
• Automation equipment utilizing bipolar stepper motors

Procurement Notes

Verify the specific suffix 'VF' against the manufacturer's official documentation to confirm package type and moisture sensitivity level. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may apply. Ensure RoHS compliance requirements are met for the specific revision. Check humidity sensitivity classification for proper storage and handling procedures during assembly.

Selection Notes

Select this component when a fully integrated bipolar stepper driver with parallel interface is required. The 800 mA output current suits moderate load applications. The 32-SSOP package offers space savings compared to larger packages. Verify that the system voltage remains within the 10 V to 34 V operational window. Consider the thermal performance characteristics given the power dissipation limits of the SSOP-32 package.
