LB11861H-TLM-H

Overview

The LB11861H-TLM-H is a fan motor driver manufactured by onsemi, designed for controlling small DC motors in cooling applications. It operates within a supply voltage range of 5.5 V to 16 V and features a low operating supply current of 15 mA. The device is housed in an SSOP-J-20 surface-mount package with dimensions suitable for compact designs. It supports a power dissipation of 800 mW and functions reliably across a temperature range from -30°C to +95°C. The component exhibits moisture sensitivity level 3 (168 hours) and is supplied in tape and reel packaging.

Feature Summary

• Integrated circuit dedicated to fan and motor control applications
• Surface-mount SSOP-J-20 package design for space-constrained layouts
• Operates with low quiescent current consumption

Applications

• Fan motor drivers
• Motion controllers
• Ignition controllers

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that availability is restricted or unavailable through standard retail outlets. Verification of current stock status should be conducted directly with authorized distributors or specialized surplus suppliers like Rochester Electronics, as inventory levels fluctuate and are not guaranteed. Compliance documentation such as RoHS and REACH status remains available for review prior to procurement attempts.

Selection Notes

Engineers selecting this part must account for its discontinued status when designing new hardware. The SSOP-J-20 footprint and specific voltage limits (5.5V–16V) define its integration constraints. Due to the EOL classification, long-term supply chain stability cannot be assured. Design reviews should prioritize identifying alternative components with compatible pinouts and electrical characteristics to ensure future manufacturability and maintenance support.

Part Context

The LB11861H belongs to the LB11861 series of motor drivers produced by onsemi. This family targets low-power motor control tasks, specifically optimized for fan applications in consumer electronics and industrial equipment. The TLM-H suffix denotes the specific tape-and-reel packaging configuration used for automated assembly processes, distinguishing it from other packaging variants within the same product line.

Replacement Considerations

Public records identify the LB11861H-MPB-E as an alternative packaging option for the same functional core. No other direct substitute part numbers are confirmed in the provided documentation. Engineers requiring different form factors should evaluate this variant, though supply status may vary similarly due to the overall product lifecycle stage.
