L99PM72GXPTR

Power Management - Specialized Overview

The L99PM72GXPTR is an automotive-grade Power Management IC in a PowerSSO-36 package, certified to AEC-Q100 standards. It operates within a supply voltage range of 6 V to 18 V and supports an extended temperature range from -40°C to +150°C. The device integrates two 5 V low-drop voltage regulators with outputs capable of delivering 100 mA and 250 mA respectively. It features embedded LIN 2.1 and high-speed CAN transceivers compliant with ISO 11898-2/-5 and SAE J2284. Additional integrated components include five fully protected high-side drivers, two low-side drivers, two operational amplifiers, and four internal PWM timers.

Power Management - Specialized Feature Summary

• Integrates advanced high-speed CAN transceiver with local failure and bus failure diagnosis capabilities
• Provides enhanced system standby functionality with programmable local and remote wake-up options
• Includes five fully protected high-side drivers equipped with an internal four-channel PWM generator
• Features complete three-channel contact monitoring interface with programmable cyclic sense functionality

Power Management - Specialized Applications

• Automotive electronic control units requiring integrated power management
• Systems utilizing LIN 2.1 and high-speed CAN physical communication layers
• Applications demanding ultra-low quiescent current during standby modes
• Industrial applications requiring robust diagnostic and protection features

Power Management - Specialized Procurement Notes

Verify the specific suffix GXPTR corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the AEC-Q100 qualification meets the specific reliability standards mandated by the target automotive application. Ensure input voltage constraints remain within the 6 V to 18 V operational window to maintain regulator stability and transceiver performance throughout the system lifecycle.

Power Management - Specialized Selection Notes

Select this component when a single IC solution is needed to combine power distribution, communication interfaces, and driver outputs. The integration of both LIN and HS CAN transceivers reduces bill-of-materials complexity compared to discrete solutions. Consider the thermal characteristics of the PowerSSO-36 package for heat dissipation requirements in enclosed environments. Evaluate the need for the specific high-side driver protection features against potential load fault conditions.

Power Management - Specialized Part Context

This part belongs to the L99PM series of specialized power management ICs designed for automotive electronics. It shares architectural similarities with the L99PM62GXP but offers enhanced CAN transceiver features including selective wake-up functionality per ISO 11898-6. The series targets applications requiring high integration levels to minimize board space and improve system reliability through reduced interconnect points.

Power Management - Specialized Replacement Considerations

The L99PM62GXPTR serves as a related variant within the same family, though it lacks the selective wake-up capability found in the L99PM72GXPTR. Verify pin-to-pin compatibility and software register mapping before substitution, as functional differences in the CAN transceiver diagnostics may require firmware adjustments.
