LB11970FV-W-AH

Overview

The LB11970FV-W-AH is a single-phase brushless DC motor controller and driver manufactured by onsemi. It integrates control logic and power stages within an 18-pin SSOP package. The device supports a supply voltage range of 4.5V to 16V and operates with load voltages starting from 3.5V. It features a PWM parallel interface for command input and utilizes a half-bridge output configuration to drive the motor windings. Designed for applications requiring up to 1.2A current, it provides a compact solution for fan motor control systems.

Feature Summary

• Fully integrated control and power stage architecture
• PWM parallel interface for digital control
• Half-bridge output configuration

Applications

• Single-phase fan motor control
• Brushless DC motor drives
• Appliance cooling systems

Procurement Notes

Verify the specific suffix 'W-AH' against official onsemi documentation to confirm tape-and-reel packaging and material compliance status. Ensure the ordering part number matches the exact electrical specifications required for the target application circuit design.

Selection Notes

Select this component when a single-phase BLDC motor requires an integrated driver solution with a 4.5V to 16V supply range. The 1.2A current capability and 18-pin SSOP package make it suitable for space-constrained designs in consumer electronics and small appliance cooling applications.

Part Context

This part belongs to the LB11970 series of motor controllers. It shares functional similarities with variants like the LB11970RV-W-AH but differs in pinout or internal configuration. The series targets low-power single-phase motor applications requiring integrated control and power management.

Replacement Considerations

Check for direct pin-compatible alternatives within the LB11970 family. Verify that any substitute maintains the same 18-pin SSOP footprint and compatible voltage/current ratings.
