Overview
The LB1668M-MPB-E is a bipolar motor driver IC manufactured by onsemi, designed for driving two-phase unipolar brushless motors. It features a half-bridge output configuration with two channels and utilizes logic interface control. The device is housed in a 14-MFPS surface-mount package, specifically a 14-LSOP with a width of 4.40mm. It operates within a supply voltage range of 6.4V to 7V and supports load voltages of 12V and 24V. The component functions reliably across an operating temperature range of -30°C to 80°C (TA).
Feature Summary
- Designed for two-phase unipolar brushless motor applications.
- Integrates dual half-bridge output configurations.
- Compatible with standard logic interface signals.
Applications
- DC motor control systems
- General purpose motor driving
Procurement Notes
Verify current availability status as the product may be discontinued or subject to end-of-life notices. Confirm that the specific suffix matches the required package and compliance specifications. Check for official replacement recommendations from the manufacturer if this part is no longer in active production. Ensure environmental compliance documents are reviewed prior to integration.
Selection Notes
Select this component for designs requiring dedicated bipolar drive for two-phase unipolar motors. Consider the 14-pin LSOP package constraints and thermal performance within the specified temperature range. Verify that the 6.4V to 7V supply requirement aligns with the system power architecture. Evaluate the 12V and 24V load voltage support against motor specifications.
Part Context
This device belongs to the LB1668 family of motor drivers from onsemi. It is functionally similar to variants such as the LB1668M-TLM-E and LB1668M-TLM-H, which share the same core driver capabilities but may differ in packaging or ordering suffixes. The family targets low-power brushless motor applications.
Replacement Considerations
Official substitute part numbers include LB1668M-TLM-E and LB1668M-TLM-H. These variants maintain the same functional description as two-phase unipolar brushless motor drivers. Verify package compatibility and electrical parameters before substitution.
