LB11693H-TRM-E

Overview

The LB11693H-TRM-E is a fully integrated three-phase brushless DC motor driver manufactured by onsemi. It operates within a supply voltage range of 8 V to 28 V and delivers an output current of 1.8 A. The device features a maximum output voltage of 5.3 V and a power dissipation rating of 900 mW. Designed for surface mount installation, it utilizes a 36-pin HSOP package (HSOP-36R). The component supports an operating temperature range from -40 °C to +85 °C and includes humidity sensitivity classification.

Feature Summary

• Fully integrated control and power stage for three-phase BLDC motors
• Supports PWM modulation for precise motor speed and torque control
• Integrated protection mechanisms against thermal overload and overcurrent conditions

Applications

• Camera autofocus and zoom actuators in mobile devices
• Optical drive spindle motors in office automation equipment
• Small fan motors in consumer electronics

Procurement Notes

Verify the specific suffix TLM versus TRM when sourcing, as packaging or tape specifications may differ between distributors. Confirm end-of-life status with the manufacturer, as this model is listed as discontinued. Ensure compatibility with existing PCB footprints for the 36-HSOP-R package during replacement planning.

Selection Notes

Select this component for applications requiring compact integration of driver and controller logic. The 1.8 A current rating suits small actuators rather than high-power loads. Evaluate the 36-pin package size against available board space. Consider the -40 °C to +85 °C range for standard commercial environments.

Part Context

This part belongs to the LB11693JH series of intelligent power devices designed for low-voltage, low-current motor control. It represents onsemi's solution for miniaturizing motor drive circuits in portable electronics. The series focuses on reducing external component count by integrating gate drivers and logic into a single IC.
