LB11660RV-TLM-E

Overview

The LB11660RV-TLM-E is a BLDC motor controller by onsemi, designed for low-voltage applications. It operates within a supply voltage range of 4 V to 15 V and supports a maximum collector current of 1.5 A. The device features a typical switching frequency of 23 kHz and has a converter rated power of 0.8 W. Housed in a 16-pin SSOP package with dimensions of 5.2 x 4.4 x 1.3 mm, it functions reliably between -30 °C and +95 °C.

Feature Summary

• Integrated control logic specifically engineered for Brushless DC (BLDC) motor commutation
• Capable of driving loads up to 1.5 A with a wide operating voltage window from 4 V to 15 V
• Operates at a typical switching frequency of 23 kHz for efficient motor performance

Applications

• Brushless DC motor control systems
• Low-voltage industrial automation actuators
• Portable electronic devices requiring precise fan or pump regulation

Procurement Notes

Verify the exact suffix TLM-E against the manufacturer's latest datasheet to confirm pinout and thermal specifications. Ensure the SSOP-16 footprint matches the target PCB design. Confirm RoHS compliance status if required by specific regional regulations. Cross-reference the 1.5 A current rating with actual load requirements to prevent overheating.

Selection Notes

Select this component when a dedicated BLDC driver is needed for voltages between 4 V and 15 V. The 1.5 A output capability suits moderate-load applications. The 23 kHz switching frequency offers a balance between acoustic noise and efficiency. The SSOP-16 package provides a compact solution for space-constrained designs requiring integrated motor control logic.

Part Context

This part belongs to onsemi's motor controller portfolio, focusing on single-phase or simple multi-phase BLDC applications. It integrates gate drive and control logic, reducing external component count compared to discrete solutions. The device is optimized for cost-sensitive consumer and industrial electronics where reliable commutation is critical without complex microcontroller intervention.

Replacement Considerations

Check for direct pin-to-pin replacements within the LB116xx series. Verify that alternative parts support the same 4–15 V range and 1.5 A current limit. Ensure the replacement maintains the 23 kHz switching characteristic if acoustic performance is a constraint.
