LB11899J-TRM-E

Overview

The onsemi LB11899J-TRM-E is a fully integrated bipolar motor driver designed for disk drive applications. It features a parallel and PWM interface, combining control logic with power output stages. The device supports load voltage capabilities ranging from 8V to 16V and 8V to 28V, with an output current rating of 200mA. It incorporates eight half-bridge outputs and operates within a junction temperature range of -20°C to 75°C (TA). The component is housed in a 44-LSSOP package with an exposed pad, measuring 0.220 inches (5.60mm) in width.

Feature Summary

• Integrates control and power sections into a single fully integrated component
• Supports both parallel and PWM interface modes for flexible control
• Features eight half-bridge outputs for versatile motor driving configurations

Applications

• Disk drive motor controllers
• Brushless DC (BLDC) motor applications
• Brushed DC motor applications

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging and environmental compliance standards. Confirm that the 44-LSSOP exposed pad package matches the target PCB footprint and thermal design requirements. Cross-reference the RoHS status and lead-free specifications against project constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for disk drive motors is required. The dual voltage range options allow adaptation to different system power rails. Ensure the 200mA output current meets the motor's operational demands. The exposed pad package necessitates adequate thermal management on the printed circuit board to maintain performance within the specified temperature range.

Part Context

This part belongs to the onsemi motor driver portfolio, specifically targeting general-purpose motion control needs. It falls under the broader category of power management ICs and motor control solutions. The device serves as a specialized controller for electromechanical systems requiring reliable bipolar motor driving capabilities in a surface-mount form factor.

Replacement Considerations

The LB11899J-MPB-E is a documented alternative variant within the same product family. Verify pinout compatibility and package dimensions before substitution. Ensure that any replacement maintains the required voltage and current ratings for the specific application environment.
