L99MOD51XPTR

Specialized ICS Overview

The L99MOD51XPTR is a microcontroller-driven multifunctional actuator driver for automotive applications, housed in a PowerSSO-36 package. It integrates three half bridges and two high-side drivers to control up to two DC motors and two grounded resistive loads. The device features one half bridge rated for 7.4 A (RDSon = 150 mΩ) and two half bridges rated for 5 A (RDSon = 200 mΩ). Two high-side drivers support 1.25 A loads (RDSon = 800 mΩ). Standby current consumption is typically less than 3 μA at Tj ≤ 85 °C. All outputs include short circuit protection, over-temperature protection, open-load diagnostics, and overload diagnostics.

Specialized ICS Feature Summary

• AEC-Q100 qualified for automotive reliability
• Integrated SPI interface for operation mode control and diagnostic readout
• Programmable soft start function for handling high inrush currents
• Charge pump output provided for external reverse polarity protection

Specialized ICS Applications

• Automotive body and convenience systems requiring multiple motor control
• Driving bulbs, LEDs, or sensors with protected supply configurations
• Actuator drivers for wipers, seats, or windows

Specialized ICS Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to the Tape and Reel packing format as defined in the manufacturer's device summary table. Confirm that the PowerSSO-36 EPD supplier device package matches the target PCB footprint requirements. Ensure the component grade meets the specified Automotive qualification standards before integration into production designs.

Specialized ICS Selection Notes

Select this component when designing circuits requiring up to five independent outputs with mixed half-bridge and high-side capabilities. Verify that the load current requirements do not exceed the 7.4 A limit for OUT1 or the 5 A limit for OUT2 and OUT3. Consider the thermal performance of the PowerSSO-36 package if operating near maximum current limits or elevated junction temperatures.

Specialized ICS Part Context

The L99MOD51XPTR belongs to the L99MOD family of multi-output drivers from STMicroelectronics. This family includes variants such as the L99MOD50XP, which offers different output configurations including six half bridges and five high-side drivers. The L99MOD series is specifically engineered for automotive applications requiring robust actuator control and comprehensive diagnostic feedback via a serial peripheral interface.

Specialized ICS Replacement Considerations

The L99MOD50XP is a related device within the same product family but features distinct output configurations, including six half bridges and five high-side drivers. Direct substitution requires verification of pin compatibility and confirmation that the alternative device's output current ratings and RDSon values meet the specific application requirements.
