LB1920-N-E

Overview

The LB1920-N-E is a three-phase bipolar brushless motor driver IC designed for office automation applications. It serves as an output current-improved version of the LB1824, offering enhanced drive capabilities for brushless motors. The device supports digital speed control and is engineered to interface directly with microprocessors or logic circuits. It integrates necessary protection features and driving circuits within a single package to simplify system design for fan and pump applications.

• Output current-improved performance relative to predecessor models
• Supports digital speed control interfaces
• Designed specifically for office automation equipment

Applications

• Office automation fans
• Printer cooling systems
• Copier internal mechanisms
• Pump drives in office equipment

Procurement Notes

Verify the manufacturer designation carefully, as Sanyo Semiconductor assets were acquired by Onsemi. Ensure the part number suffix matches the specific package and tape-and-reel configuration required for your assembly line. Cross-reference the datasheet revision date to confirm compatibility with your system's voltage and logic levels before finalizing procurement orders.

Selection Notes

Select this component when a dedicated three-phase driver for bipolar brushless motors is required in office automation contexts. It is suitable for designs needing improved output current handling compared to older generations like the LB1824. Consider its digital control interface requirements and ensure the operating voltage range aligns with the target application's power supply specifications.

Part Context

This component belongs to the Sanyo (now Onsemi) series of motor drivers intended for low-power office automation. It replaces earlier iterations like the LB1824 with improved current characteristics. The LB1920 family is distinct from general-purpose H-bridge drivers, focusing specifically on the commutation needs of three-phase brushless motors found in printers and copiers.

Replacement Considerations

The LB1920 is explicitly documented as an improved version of the LB1824. Verify pin-to-pin compatibility if substituting into existing designs originally using the LB1824. No other direct substitute part numbers are confirmed in the provided documentation.
