LB11660FV-TLM-H

Overview

The LB11660FV-TLM-H is a single-phase bipolar drive half-predriver motor driver manufactured by onsemi. It is designed to facilitate direct PWM driver motor circuits with high efficiency. The device features two outputs capable of delivering an output current of 1.5A and supporting an output voltage of up to 20V. It is specifically intended for driving single-phase fan motors. The component is housed in a 16-SSOP package, providing a compact solution for motor control applications requiring precise bipolar drive characteristics.

Feature Summary

• Single-phase bipolar drive half-predriver architecture
• Direct PWM driver circuit implementation capability
• Optimized for single-phase fan motor applications

Applications

• Single-phase fan motor control
• Direct PWM motor driver circuits
• Bipolar drive predriver stages

Procurement Notes

Verify the specific suffix TLM-H against the official onsemi datasheet to confirm package type and tape-and-reel specifications. Ensure the application environment remains within the specified 20V output voltage and 1.5A output current limits. Confirm that the 16-SSOP package dimensions align with the PCB footprint requirements. Cross-reference the part number with the latest product change notifications to ensure no unannounced process changes affect performance or compatibility.

Selection Notes

Select this component when a dedicated half-predriver for single-phase bipolar fan motors is required. It is suitable for designs needing direct PWM integration without additional complex logic. Consider the 16-SSOP package size for space-constrained layouts. Verify that the thermal dissipation capabilities of the SSOP package are sufficient for the expected operating current and ambient temperature conditions in the final assembly.

Part Context

This part belongs to onsemi's motor drivers and controllers category, specifically under bipolar parallel PWM drivers. It serves as a specialized predriver stage rather than a full H-bridge or complete motor controller. The component is part of a broader portfolio aimed at efficient motor management in consumer and industrial appliances, focusing on simplified circuit design for single-phase applications.

Replacement Considerations

Check for pin-compatible alternatives within the same family if supply constraints exist. Verify that any substitute maintains the 1.5A current rating and 20V voltage support. Ensure the replacement also supports single-phase bipolar drive configurations. Consult onsemi documentation for any recommended cross-reference parts to guarantee functional equivalence.
