L9958SBTR

Overview

The L9958SBTR is a fully integrated bipolar stepper motor driver manufactured by STMicroelectronics. It operates on a CMOS technology platform within a 16-PowerBSOP package. The device supports a supply voltage range of 4.5V to 5.5V and handles load voltages from 4V to 28V. It delivers an output current of up to 8.6A through two half-bridge configurations. Communication is managed via an SPI interface, while the operating junction temperature spans from -40°C to 150°C.

Feature Summary

Integrates control logic and power stages for complete bipolar stepper motor management
Utilizes Serial Peripheral Interface (SPI) for digital command and status monitoring
Features robust thermal protection mechanisms suitable for high-temperature environments

Applications

Bipolar stepper motor control in automotive systems
Door actuator mechanisms requiring integrated drive solutions
General purpose motion control applications

Procurement Notes

Verify the specific suffix 'SBTR' against the official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required SPI protocol implementation and voltage levels. Confirm that the 16-PowerBSOP footprint matches the target PCB layout constraints. Check for any recent Product Change Notifications regarding assembly or material updates.

Selection Notes

Select this component when a compact, fully integrated solution for bipolar stepper motors is required. It is suitable for designs needing high current capability within a small surface-mount package. Consider the SPI interface requirements and the wide operating temperature range for harsh environment applications. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture.

Part Context

This part belongs to the L9958 family of motor drivers designed for automotive and industrial applications. It serves as a complete driver solution, eliminating the need for external power transistors. The PowerSO-16 package provides efficient heat dissipation for high-current operations. It is distinct from pre-driver ICs by including both logic and power stages.
