Overview
The LB11690H-MPB-E is a three-phase motor driver IC from onsemi, designed for automotive applications. It integrates high-voltage power stages to drive brushless DC (BLDC) motors commonly found in automotive cooling fans and pumps. The device operates within a supply voltage range of 9.5 V to 28 V, supporting standard automotive electrical systems. It features integrated protection mechanisms including overcurrent, thermal shutdown, and under-voltage lockout to ensure reliable operation in harsh environments. The component is housed in a 36-pin HSOP-R package suitable for surface mount assembly.
Feature Summary
- Integrated three-phase bridge drivers for direct BLDC motor control
- Built-in diagnostic and protection functions for system reliability
- Automotive-grade construction compliant with AEC-Q100 standards
Applications
- Automotive radiator fan motor control
- Engine cooling pump drives
- HVAC blower motor regulation
Procurement Notes
Verify the specific suffix 'MPB-E' against the official datasheet to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's current documentation. Check for end-of-life notifications or alternative recommendations if sourcing for long-term production. Ensure the supplier provides valid traceability documents for automotive grade components.
Selection Notes
Select this component when designing automotive cooling systems requiring integrated three-phase drive capabilities. Consider the operating temperature range and thermal dissipation requirements of the HSOP-R package. Evaluate the need for external gate resistors and bootstrap capacitors based on the specific motor inductance and switching frequency requirements of the application design.
Part Context
This part belongs to onsemi's LB116xx series of automotive motor drivers. These devices are engineered specifically for the demanding environment of modern vehicles, offering high integration to reduce board space and component count. The series supports various motor types used in thermal management systems across different vehicle platforms.
Replacement Considerations
