Overview
The L99MM70XPTR is a microprocessor-driven automotive application-specific standard product (ASSP) designed for LIN-controlled exterior mirror systems. It integrates a voltage regulator, LIN2.1 physical layer, and ST SPI interface. The device supports independent control of up to three DC motors and five grounded resistive loads via four half bridges, one full bridge, and multiple high-side drivers. Key specifications include a 3 A full bridge with 500 mΩ on-resistance, 6 V to 18 V supply voltage range, and operation from -40°C to +150°C in a PowerSSO-36 package.
Feature Summary
- Integrated LIN transceiver compliant with LIN2.1 and SAEJ2602 standards
- Embedded EC-glass control block with fast discharge path capabilities
- Comprehensive diagnostic features including open-load and overtemperature protection
- Programmable soft start function for managing high inrush currents
Applications
- LIN-controlled exterior wing mirror actuation
- Mirror adjustment motor control
- Electrochromic glass management
- Automotive lighting and load driving
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and variant selection. Confirm that the PowerSSO-36 package dimensions align with your PCB layout requirements. Ensure compatibility with the target vehicle's LIN bus protocol version and voltage levels before integration into the design.
Selection Notes
Select this component for applications requiring integrated LIN communication and multi-axis mirror control. It is suitable for designs needing combined motor drive and resistive load handling within a single ASSP. Consider its thermal performance and diagnostic capabilities for robust automotive environments requiring high reliability and fault detection.
Part Context
This part belongs to the L99MM70XP series of microprocessor-driven ASSPs. It is specifically engineered for automotive body electronics, focusing on exterior mirror functionalities. The device consolidates power switching, communication interfaces, and control logic to simplify system architecture and reduce bill of materials complexity in modern vehicle mirror modules.
Replacement Considerations
Consult official substitution lists for direct replacements. Verify pinout compatibility and electrical parameters if considering alternative bridge driver ICs from other manufacturers.
