Overview
The L9904TR is a motor bridge controller designed for automotive applications, featuring an ISO 9141 bus interface. It operates with a supply voltage range of 8V to 28V, supporting up to 40V maximum overvoltage. The device includes a step-up converter allowing operation at 6V and features reverse battery protection via a charge pump. Key electrical parameters include a quiescent current in standby mode of less than 50μA and a PWM operation frequency up to 30kHz. It is housed in a SOIC-20 package and is qualified under AEC-Q100 standards.
Feature Summary
- Integrated programmable cross-conduction protection time
- Real-time diagnostic capabilities for system monitoring
- Comprehensive protection against overvoltage, undervoltage, short circuit, and thermal events
- ISO 9141 compatible interface for seamless integration
Applications
- Control circuits for power MOS bridge drivers in automotive systems
- Motor control applications requiring ISO 9141 communication
- Automotive ignition and motion control systems
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required packaging formats such as cut tape or reel. Confirm that the component meets AEC-Q100 qualification requirements for automotive deployment. Check moisture sensitivity levels prior to storage and handling to prevent damage during assembly processes.
Selection Notes
Select this component for automotive designs requiring robust motor bridge control with integrated diagnostics. Ensure the application supports the specified 8V to 28V operating range and utilizes ISO 9141 interfaces. Consider the SOIC-20 package constraints and thermal management needs associated with the integrated protection features.
Part Context
The L9904 belongs to STMicroelectronics' family of motor and motion controllers.
