L99MOD53XPTR

Specialized ICS Overview

The L99MOD53XPTR is a microcontroller-driven multifunctional actuator driver for automotive applications, housed in a PowerSSO-36 package. It integrates five half bridges and three high-side drivers to control up to three DC motors and grounded resistive loads. The device features an integrated SPI interface for operating modes including forward, reverse, brake, and high impedance. Electrical specifications include a supply voltage range of 7 V to 28 V, with output current capabilities reaching 10 A for specific outputs. Key parameters include an on-resistance of 1600 mΩ for half bridges and 100 mΩ for the high-side OUT8 driver.

Specialized ICS Feature Summary

• AEC-Q100 qualified for automotive reliability
• Integrated SPI control for all operating modes and diagnostics
• Programmable soft start function for high inrush currents
• Comprehensive protection including short circuit, over temperature, open-load, and overload detection

Specialized ICS Applications

• Automotive DC motor control
• Grounded resistive load driving
• Actuator driver systems requiring multiple outputs

Specialized ICS Procurement Notes

Verify the PowerSSO-36 EPD package configuration and Tape & Reel packing format. Confirm AEC-Q100 qualification status and ensure compatibility with the required VS and VCC supply voltages. Check that the specific ordering suffix TR matches the reel quantity requirements for the production line.

Specialized ICS Selection Notes

Select this component when designing systems requiring up to three half bridges and three high-side drivers. Ensure the application supports the 7 V to 28 V supply range and utilizes SPI communication. Consider the thermal performance in the PowerSSO-36 package if driving loads near the maximum current limits of 10 A or 6 A depending on the output channel.

Specialized ICS Part Context

The L99MOD53XPTR belongs to the L99MOD5xXP family of multi-output drivers from STMicroelectronics. It shares the same PowerSSO-36 footprint and basic interface as variants like the L99MOD51XP and L99MOD54XP, differing primarily in the number and type of integrated half bridges and high-side drivers available for specific actuator configurations.

Specialized ICS Replacement Considerations

L99MOD51XPTR: Offers fewer drivers (5 half bridges, no dedicated high-side drivers). L99MOD54XPTR: Provides six drivers (four half bridges, two high-side drivers). Verify pinout compatibility and electrical ratings before substitution.
