Overview
The LV8811G-AH is a three-phase brushless DC motor driver manufactured by onsemi, designed for PWM full-wave control. It operates within a load voltage range of 3.6 V to 16 V and delivers an output current of 2 A per phase. The device functions at working frequencies between 20 kHz and 50 kHz with a power dissipation rating of 2.5 W. It requires a supply current of 4.5 mA and provides a 3 V output voltage. The component supports surface mount installation in a TSSOP-20 package and withstands operating temperatures from -40°C to +105°C.
Feature Summary
- Integrates three-phase BLDC motor control with PWM full-wave driving capability
- Supports wide input voltage ranges suitable for various low-voltage applications
- Includes thermal protection mechanisms to manage power dissipation up to 2.5 W
- Features humidity sensitivity classification requiring careful handling during storage
Applications
- Brushless DC motor control systems
- Industrial motion control devices
- Automotive ignition controllers
- Small appliance drive circuits
Procurement Notes
Verify the specific ordering suffix AH against official onsemi documentation to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Check for moisture sensitivity level requirements to ensure proper handling protocols are followed during assembly. Validate that the TSSOP-20 package matches the design constraints. Review end-of-life notices as availability may be restricted.
Selection Notes
Select this component when designing three-phase BLDC motor drives requiring moderate current levels around 2 A. Ensure the application voltage stays within the 3.6 V to 16 V operational window. Consider the TSSOP-20 footprint for PCB layout compatibility. Evaluate thermal management needs given the 2.5 W power dissipation limit. Verify that the operating temperature range of -40°C to +105°C meets environmental demands.
Part Context
The LV8811G belongs to onsemi's family of motor and motion controllers. This series targets applications needing integrated three-phase drive solutions without external complex circuitry. The device simplifies BLDC motor implementation by combining control logic with power drivers. It serves as a compact solution for embedded motion control tasks in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult onsemi technical support or authorized distributors for direct replacements. Verify electrical compatibility and pin configuration before considering alternative components.
