SMA6821MHLF2452

Overview

The SMA6821MHLF2452 is a full-integrated motor driver IC manufactured by Sanken Electric USA Inc. Designed for AC and synchronous stepper motors, it integrates control logic and power stages using Power MOSFET technology. The device operates within a supply voltage range of 13.5V to 16.5V and supports load voltages up to 200V maximum. It provides an output current of 2A and features three half-bridge outputs. The component is housed in a 24-SIP (LF2451) through-hole package and functions reliably across a junction temperature range of -20°C to 150°C.

Feature Summary

• Integrates complete control logic and power stage circuitry into a single unit
• Utilizes Power MOSFET architecture for efficient switching performance
• Provides three independent half-bridge output configurations

Applications

• Home appliance motor control systems

Procurement Notes

Verify the specific suffix LF2452 against official Sanken Electric documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering information matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to validate technical parameters before finalizing procurement specifications.

Selection Notes
