Product Details
L99MOD53XPTR - Automotive Multi-Output Driver
STMicroelectronics L99MOD53XPTR integrates five half bridges and three high-side drivers for microcontroller-directed automotive loads. SPI controls operating modes and returns diagnostic information. The exact TR ordering code is the PowerSSO-36 tape-and-reel option.
Engineering summary checked against ST's L99MOD53XP Rev. 5 production data sheet.
Overview
L99MOD53XP is a multifunction automotive actuator driver. Five half bridges can operate as three motor-control paths, 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 each load combination and the thermal design against the full data sheet.
Key Advantages
Five half bridges and three high-side outputs in one automotive device.
Read back open-load, overload and thermal conditions.
SPI mode selection, PWM control and programmable soft start support varied loads.
AEC-Q100 qualification is stated in ST's data sheet.
Feature Summary
OUT1 through OUT5 form protected bidirectional output stages.
OUT6, OUT7 and OUT8 serve grounded loads with channel-specific capability.
Outputs include short-circuit, over-temperature, open-load and overload monitoring.
An output is provided to drive an external reverse-polarity protection MOSFET.
Package & Footprint
The ST data sheet identifies L99MOD53XPTR 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 exposed-pad and PCB copper guidance.
- Connect every required VS, GND and duplicated output pin.
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's PowerSSO-36 top-view pin table defines these principal connections:
Ground references; all four must be connected for full output capability.
High-side output; both pins must be connected for full current capability.
Protected half-bridge outputs.
Power supply pins; ST requires all connected.
24-bit serial control and diagnostic interface.
Duplicated half-bridge connections; connect each pin pair.
Protected high-side outputs for compatible resistive loads.
Logic supply, charge pump, PWM input and current-monitor/second-PWM function.
Pins 22, 24, 29, 30 and 34 are not connected. Use the complete ST pin table for layout and load design.
Key Specifications

| Control word | 24-bit SPI, LSB first |
| Standby supply current | Below 6 µA typical at Tj ≤ 85 °C |
| DC VS absolute maximum | -0.3 V to 28 V; not an operating recommendation |
| Logic supply absolute maximum | -0.3 V to 5.5 V |
| Qualification | AEC-Q100, per ST data sheet |
Feature ratings, absolute maxima and typical values do not replace the operating, load, temperature and thermal conditions in ST's electrical tables.
Replacement Considerations
Compare bridge topology, channel-current limits, RDS(on), SPI command and status mapping, protection thresholds, supply requirements, thermal performance and the controlled package drawing before considering another driver. Other L99MOD5xXP devices are not automatic drop-in replacements. No internal substitute link is provided without exact API catalog verification.
Manufacturer Information
STMicroelectronics lists the exact L99MOD53XPTR order code as the PowerSSO-36 tape-and-reel automotive option. The DS12617 Rev. 5 production data sheet supplies pin definitions, electrical tables, diagnostic behavior and mechanical information. Use current controlled ST documentation for production qualification.
Applications
Configure compatible half-bridge combinations for 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 L99MOD53XPTR marking, lot traceability, automotive qualification documents, package and handling data. Test SPI diagnostics and every intended load combination under worst-case supply and junction-temperature conditions.
FAQ
What does the TR suffix designate?
ST's device summary lists L99MOD53XPTR as the PowerSSO-36 tape-and-reel order code.
How many output stages are integrated?
The architecture provides five half bridges and three high-side outputs.
Can the catalog PowerBFSOP footprint be used directly?
No. Reconcile it against ST's controlled PowerSSO-36 mechanical and thermal-pad 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.
