LB1641L-E

Overview

The LB1641L-E is a bipolar motor driver IC manufactured by onsemi, designed for driving small DC motors in consumer electronics and appliances. It utilizes a Single In-line Package (SIP) with 10 pins, measuring 24 x 3.25 x 6.5 mm. The device supports a minimum operating supply voltage of 5 V and a maximum of 18 V. It features a maximum collector-emitter voltage of 18 V and a maximum IGBT collector current rating of 1.6 A. The component operates within a temperature range of -25 °C to +75 °C.

Feature Summary

• Integrated bipolar motor driver architecture suitable for direct interface with logic circuits
• Single in-line package design facilitating through-hole mounting on printed circuit boards
• Operational capability across standard low-voltage power supply ranges

Applications

• Small DC motor control in household appliances
• Motor drive circuits in consumer electronic devices
• Industrial control systems requiring low-power motor actuation

Procurement Notes

Verify the specific suffix 'L' against the official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the application environment remains within the specified -25 °C to +75 °C operating range. Confirm that the load current does not exceed the 1.6 A maximum rating under all operating conditions. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a through-hole SIP package is preferred over surface-mount alternatives for mechanical stability or legacy board designs. Consider the 18 V maximum voltage limit when designing power supplies. Evaluate the 1.6 A current capacity against peak motor startup currents to prevent thermal overload. Verify logic level compatibility for control signals.

Part Context

This part belongs to onsemi's standard product portfolio focused on motor control solutions. It complements the company's broader range of drivers and power management devices. The SIP form factor distinguishes it from modern surface-mount offerings, targeting applications where manual assembly or specific mechanical constraints necessitate through-hole technology.

Replacement Considerations

Consult official cross-reference lists for equivalent bipolar motor drivers. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Generic replacements may differ in thermal resistance or package dimensions.
