LV8732VL-TLM-H

Overview

The LV8732VL-TLM-H is a dual-channel DC motor driver IC from onsemi, designed for automotive and industrial applications. It integrates two H-bridge drivers capable of delivering continuous current with peak support, featuring integrated high-side and low-side N-channel MOSFETs. The device supports PWM control inputs for direction and speed regulation. Key electrical characteristics include a wide operating voltage range, typically up to 16V or 24V depending on the specific variant configuration, and thermal shutdown protection. It utilizes a compact QFN package to minimize board space while maintaining robust performance in noisy environments.

Feature Summary

• Integrates dual H-bridge motor drivers with built-in power MOSFETs for direct motor control
• Includes comprehensive protection mechanisms such as over-current, short-circuit, and thermal shutdown
• Supports flexible PWM input signals for precise speed and direction management
• Designed for low EMI operation through controlled switching frequencies

Applications

• Automotive seat adjustment motors
• Power window and sunroof actuators
• HVAC blower fan control systems
• Industrial automation linear actuators

Procurement Notes

Verify the exact suffix and tape/reel specifications against the official datasheet before ordering. Confirm that the intended application voltage and current requirements fall within the absolute maximum ratings defined by onsemi. Ensure proper thermal management design is implemented due to the integrated power stage nature of the component. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact solution for driving two small DC motors is required in automotive or industrial settings. It is suitable for applications needing integrated protection features to reduce external component count. Consider the thermal dissipation capabilities of the QFN package relative to the expected duty cycle and ambient temperature conditions during system design.

Part Context

This part belongs to onsemi's LV87xx series of dual H-bridge motor drivers, widely used in automotive body electronics. The series is known for integrating power switches and control logic into a single package, simplifying PCB layout and reducing assembly costs compared to discrete solutions. It complements other onsemi motor control offerings like gate drivers and standalone MOSFETs.

Replacement Considerations

Check for pin-compatible alternatives such as the LV8730 or LV8731 series if different current ratings are needed. Verify functional equivalence regarding control logic and protection thresholds before substituting. Ensure any replacement part meets the same automotive qualification standards if used in vehicle applications.
