LB1861-E

Overview

The LB1861-E is a bipolar motor driver IC manufactured by onsemi, housed in a SIP-10 package. It supports a supply voltage range of 5 V to 18 V and delivers a maximum collector current of 1.6 A. The device operates within a temperature range of -25 °C to +75 °C and measures 24 x 3.25 x 6.5 mm.

Feature Summary

• Integrated bipolar motor driver architecture
• Through-hole SIP-10 packaging for standard mounting

Applications

• Small DC motor control systems
• Relay driving circuits
• Solenoid actuation applications

Procurement Notes

Verify the exact suffix against official onsemi documentation to confirm pinout compatibility and thermal specifications. Ensure the supplier provides traceable datasheets matching the LB1861-E designation. Confirm that the component meets the specified operating temperature range for your intended environment before finalizing procurement.

Selection Notes

Select this component when a through-hole solution is required for low-power motor or relay control. The 1.6 A current rating suits small loads, while the 5 V to 18 V input range offers flexibility for various logic levels. Consider the SIP-10 form factor for ease of manual assembly or prototyping where surface-mount options are less suitable.

Part Context

This part belongs to onsemi's legacy bipolar motor driver lineup. These components were designed for straightforward interface with microcontrollers and logic gates. The SIP-10 package distinguishes it from modern surface-mount alternatives, targeting industrial and consumer appliances requiring robust, simple drive solutions.

Replacement Considerations

Consult onsemi's official obsolescence notices for direct replacements. Verify pin-to-pin compatibility if substituting with newer series. Cross-reference thermal resistance and current ratings to ensure equivalent performance in the target application.
