Overview
The LB1664N-E is a two-phase unipolar brushless motor driver manufactured by Sanyo. It features an output current capacity of 1.5 A and includes on-chip output protect zener diodes rated at 60 V. The output stage withstand voltage is specified at 85 V. This component is designed for driving two-phase unipolar brushless motors, integrating protection mechanisms within the driver circuitry to safeguard against electrical overstress during operation.
Feature Summary
- Integrated protection via on-chip zener diodes
- Designed for two-phase unipolar brushless motor control
- High output stage voltage withstand capability
Applications
- Two-phase unipolar brushless motor drive systems
- Industrial motor control applications requiring integrated protection
- Electronics utilizing Sanyo motor driver solutions
Procurement Notes
Verify the manufacturer designation as Sanyo or its successor entities, such as onsemi or Rochester Electronics, depending on the production era. Confirm the package type, typically DIP-16, matches the required footprint. Ensure the part number suffix '-E' is present if environmental compliance or specific binning is required. Cross-reference with official datasheets to confirm the 1.5 A output current and 60 V zener protection specifications align with system requirements.
Selection Notes
Select this component when a dedicated driver for two-phase unipolar brushless motors is needed. The integrated 60 V zener diodes provide necessary overvoltage protection without external components. The 1.5 A output current rating suits moderate power motor applications. Consider the 85 V output stage withstand voltage for systems with potential inductive kickback. Verify compatibility with the control logic levels used in the target design.
Part Context
The LB1664N-E belongs to the LB16xx series of motor drivers from Sanyo Semicon Device. This series includes variants like the LB1660N and LB1661, which share similar protective features but may differ in specific voltage ratings or pin configurations. The LB1664N-E is specifically tailored for two-phase unipolar configurations, distinguishing it from drivers intended for bipolar or three-phase motors.
Replacement Considerations
Check for direct substitutes within the LB16xx family, such as the LB1660N, noting differences in zener diode ratings. Verify availability from authorized distributors or secondary market suppliers like Rochester Electronics if original Sanyo stock is depleted. Ensure pinout compatibility before substituting.
