Product Details
L99MOD54XPTR - Automotive Multi-Output Driver
STMicroelectronics L99MOD54XPTR integrates three half bridges and three high-side drivers for microcontroller-directed automotive loads. SPI controls modes and returns diagnostic information. The exact TR ordering code is the PowerSSO-36 tape-and-reel option.
Engineering summary checked against ST's L99MOD54XP Rev. 4 data sheet and exact-part listing.
Overview
L99MOD54XP is a multifunction automotive actuator driver. Three half bridges can operate DC motors or other bidirectional loads, while three high-side channels drive grounded resistive loads. The integrated SPI interface selects forward, reverse, brake and high-impedance states and reports protection and diagnostic events. Confirm the selected load and thermal design against the full data sheet.
Key Advantages
Three half bridges and three high-side outputs in one device.
Read back open-load, overload and thermal conditions.
SPI mode selection with PWM control and programmable soft start.
AEC-Q100 qualification is stated in ST's data sheet.
Feature Summary
OUT1, OUT2 and OUT3 support motor and actuator switching.
OUT4, OUT5 and OUT6 serve grounded loads with channel-specific capability.
Short-circuit, over-temperature, open-load and overload diagnostics.
External reverse-polarity protection MOSFET gate-drive output.
Package & Footprint
The ST data sheet identifies L99MOD54XPTR as PowerSSO-36 supplied on tape and reel. The LCDChip catalog records 36-PowerBFSOP (0.295 inch, 7.50 mm width), mapped in its package registry to 36-PowerBFSOP. These labels do not establish footprint equivalence. Review ST's controlled PowerSSO-36 mechanical and thermal-pad drawing before PCB release.
- Verify body outline, lead pitch and pin-one orientation.
- Follow ST's PowerSSO-36 thermal-pad and PCB copper guidance.
- Confirm all power and ground connections before full-load operation.
The registered JPG is absent locally and returns HTTP 404 on the production site; keep the page under review until the image and package mapping are confirmed.
Pin Functions
ST Rev. 4 data sheet identifies the PowerSSO-36 connections below. Use its top-view drawing for layout orientation.
Ground references; ST requires all four externally connected for full current.
High-side output; connect both pins for full current.
Half-bridge outputs for controlled loads.
Power supply pins; connect all for full current.
Serial control and diagnostic interface.
Logic supply, charge-pump output and PWM input.
Check the complete ST pin table for OUT4, OUT5, CM/PWM2 and no-connect locations.

Feature ratings and typical values do not replace the full load, temperature, supply and thermal conditions in ST's electrical tables.
Replacement Considerations
Compare bridge topology, output-current limits, RDS(on), SPI command and status mapping, protection thresholds, supply range, thermal resistance and controlled package drawing before considering another driver. Similar L99MOD devices are not automatic drop-in replacements. No internal substitute link is provided without exact API catalog verification.
Manufacturer Information
STMicroelectronics lists the exact L99MOD54XPTR ordering code as the PowerSSO-36 automotive-grade option. Its DS12616 Rev. 4 data sheet supplies pin definitions, electrical tables, load-protection behavior and mechanical information. Use the current controlled ST documentation for production qualification.
Applications
Configure half bridges for compatible automotive motors.
Drive grounded bulb or LED loads within channel limits.
Switch compatible sensor or camera supply paths.
Integrate multiple protected loads under MCU control.
Quality & Authenticity
Confirm the complete L99MOD54XPTR marking, traceability, automotive qualification documents, package and handling data. Test SPI diagnostics and each intended load under worst-case supply and junction-temperature conditions.
FAQ
What does the TR suffix designate?
ST's device summary lists L99MOD54XPTR as the PowerSSO-36 tape-and-reel order code.
How many outputs are integrated?
Three half bridges and three high-side drivers.
Can the catalog PowerBFSOP footprint be used directly?
No. Reconcile it against ST's PowerSSO-36 mechanical drawing first.
Engineering Notice
This summary is not a substitute for controlled ST documentation. The catalog and manufacturer package labels require layout reconciliation, and the registered production JPG is unavailable. Hold publication until those checks are complete.
