LB1860M-TLM-E

Overview

The LB1860M-TLM-E is a bipolar brushless DC motor controller manufactured by onsemi. It operates within a supply voltage range of 2.5 V to 9 V and delivers an output current of up to 800 mA. The device functions across an operating temperature range from -40 °C to +85 °C. It utilizes a 14-MFPS surface-mount package for integration into compact designs.

Feature Summary

• Integrates a two-speed mode select function allowing full speed or low speed operation with minimal external components
• Supports thermistor-controlled continuous operation for enhanced thermal management

Applications

• Fan motor control systems
• Brushless DC motor applications requiring speed selection
• Thermistor-protected motor drives

Procurement Notes

Verify the specific suffix TLM-E against official onsemi documentation to confirm pinout and packaging details. Confirm availability status as distribution channels may list obsolete or discontinued inventory. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component for applications requiring integrated speed control without complex external circuitry. Consider the 800 mA output limit and bipolar architecture suitability. Verify that the 14-MFPS package fits the mechanical constraints of the target design.

Part Context

This part belongs to onsemi's motor driver family, leveraging BCD technology for mixed-signal integration. It serves as a specialized solution for controlling brushless DC motors in consumer and industrial electronics where space efficiency and simplified control logic are prioritized.

Replacement Considerations

Check for direct substitutes such as the LB1836ML-TLM-E or LB11921T-TLM-E based on current requirements. Verify pin compatibility and electrical specifications before substitution.
