L99MOD50XPTR

Specialized ICS Overview

The L99MOD50XPTR is a microcontroller-driven multifunctional actuator driver for automotive applications, housed in a PowerSSO-36 EPD package. It integrates six half bridges and five high-side drivers to control up to five DC motors and five grounded resistive loads. The device features AEC-Q100 qualification and utilizes an ST-SPI 3.0 interface for mode control and diagnostics. Electrical specifications include two 6 A half bridges (RDSon = 150 mΩ), two 3 A half bridges (RDSon = 300 mΩ), and one 6 A high-side driver (RDSon = 90 mΩ). Standby current consumption is typically less than 6 μA.

Specialized ICS Feature Summary

• Integrated SPI controls forward, reverse, brake, and high impedance modes with full diagnostic readback.
• Configurable high-side drivers support dual resistance profiles: 500 mΩ for 1.5 A or 1800 mΩ for 0.4 A loads.
• Programmable soft-start function manages inrush currents for high-capacitance loads.
• Comprehensive protection includes over-current, open-load detection, temperature warning, and thermal shutdown.

Specialized ICS Applications

• Automotive door module actuators
• Seat adjustment systems
• HVAC blower motor control

Specialized ICS Procurement Notes

Verify the 'TR' suffix indicates Tape & Reel packaging as specified in the datasheet device summary table. Confirm the component grade is Automotive and that the PowerSSO-36 EPD package matches the target PCB footprint. Ensure the ordering code corresponds to the specific production revision DS12615 Rev 4.

Specialized ICS Selection Notes

Select this component when a single IC must drive multiple mixed loads including DC motors and resistive elements like bulbs or LEDs. The configurable high-side outputs allow optimization for either low-resistance incandescent loads or higher-resistance LED arrays. Verify VS supply voltage ranges from 7 V to 28 V and logic supply is within 4.5 V to 5.3 V.

Specialized ICS Part Context

The L99MOD50XPTR belongs to the L99MOD family of multi-output drivers designed for complex automotive actuation tasks. It serves as a centralized driver solution, replacing discrete MOSFET arrangements. The TR suffix specifically denotes the tape and reel shipping format suitable for automated surface-mount assembly processes.

Specialized ICS Replacement Considerations

The EVAL-L99MOD50XP evaluation board is available for testing the L99MOD50XP functionality prior to integration into final designs.
