Overview
The LB11693H-MPB-E is a three-phase brushless DC motor driver IC designed for direct PWM drive applications. It operates within a supply voltage range of 9.5V to 28V and supports load voltages in the same range. The device delivers an output current of 1.8A per phase. It is housed in a 36-pin HSOP-R EP package with exposed pad, suitable for compact motor control designs.
Feature Summary
- Direct PWM drive capability for three-phase brushless DC motors
- Integrated bipolar transistor architecture for robust switching
- Wide operating voltage range supporting common 24V fan systems
Applications
- 24V fan motor control
- General purpose BLDC motor driving
- Computer cooling systems
Procurement Notes
Verify the specific suffix MPB-E against the official onsemi datasheet to confirm tape-and-reel packaging and pinout configuration. Ensure thermal management requirements are met due to the exposed pad design. Cross-reference the part number with authorized distributors to avoid counterfeit components, as generic listings may lack verified authenticity documentation.
Selection Notes
Select this component when a dedicated three-phase BLDC driver is required for low-to-medium power applications up to 1.8A. It is appropriate for systems operating between 9.5V and 28V where direct PWM input is available. Consider the HSOP-R EP package size for PCB layout constraints and thermal dissipation needs compared to alternative packages like TRM or TLM.
Part Context
This part belongs to onsemi's line of motor controllers and drivers. It is functionally similar to variants such as LB11693H-TRM-E and LB11693H-TLM-E, which share the same core controller specifications but differ in packaging and shipping formats. The MPB-E designation specifically indicates the HSOP-R EP package type.
Replacement Considerations
LB11693H-TRM-E and LB11693H-TLM-E are confirmed functional substitutes with identical electrical characteristics. Verify that the target PCB footprint accommodates the HSOP-R EP package dimensions if replacing from other package types.
