Overview
The LV8081GQ-E is a dual DC motor driver manufactured by onsemi, designed for precise control of two independent motors. It integrates high-side and low-side MOSFETs to support bidirectional current flow, enabling forward and reverse rotation. The device features an integrated bootstrap diode and charge pump circuitry to drive the high-side N-channel MOSFETs efficiently. It supports PWM input signals for speed regulation and includes built-in protection mechanisms such as thermal shutdown and over-current detection to ensure reliable operation in various automotive and industrial applications.
Feature Summary
- Dual channel architecture for independent motor control
- Integrated high-side and low-side power stages
- Built-in thermal and over-current protection
- Supports PWM-based speed and direction control
Applications
- Automotive seat adjustment systems
- Power window and sunroof actuators
- HVAC blower motor control
- Industrial automation linear actuators
Procurement Notes
Verify the specific suffix 'GQ-E' against the official datasheet to confirm package type and temperature range. Ensure compatibility with the system's logic voltage levels and PWM frequency requirements before integration. Check for any recent lifecycle status updates or obsolescence notices from onsemi.
Selection Notes
Select this component when dual-motor synchronization or independent control is required within a compact form factor. Consider its operating temperature range and current handling capabilities relative to the load requirements. Evaluate the need for external components versus the integrated features offered by this driver.
Part Context
This part belongs to onsemi's LV80xx series of dual DC motor drivers, which are widely used in automotive electronics. The series is known for robust performance in harsh environments and integration of power management features to reduce external component count.
Replacement Considerations
Check for direct pin-to-pin replacements within the LV80xx family, such as the LV8081M or LV8081T, ensuring voltage and current ratings match. Verify that any substitute maintains the same package outline and thermal characteristics.
