LB1909M-TE-L-E

Overview

The LB1909M-TE-L-E is a monolithic bipolar motor driver manufactured by onsemi, designed for general-purpose applications. It features a full-integrated architecture combining control and power stages within a compact 10-MFPS surface-mount package. The device supports a supply voltage range of 2.5V to 16V and delivers an output current of 800mA. It utilizes a parallel interface and includes four half-bridge outputs to drive bipolar motors. The component operates reliably across a temperature range of -30°C to 85°C.

Feature Summary

• Integrates control logic and power output stages into a single monolithic IC
• Supports bidirectional operation for bipolar motor control
• Includes built-in braking functionality for rapid motor stop
• Operates with low standby current consumption

Applications

• General-purpose motor control systems
• Portable electronic devices requiring bipolar motor drivers
• Video equipment motion mechanisms
• Camera lens actuation systems

Procurement Notes

Verify the specific suffix TE-L-E against the official datasheet to confirm pinout and packaging compatibility. Confirm that the 10-MFPS package dimensions match the target PCB footprint. Check for RoHS compliance status as indicated in the manufacturer's environmental documentation. Ensure the design accounts for the specified thermal operating range during system integration.

Selection Notes

Select this component when a fully integrated solution for bipolar motors is required without external discrete power transistors. The 800mA output capability suits small to medium load requirements. Consider the 10-MFPS package size for space-constrained designs. Verify that the parallel interface logic levels are compatible with the host controller. Evaluate thermal management needs based on the 85°C maximum junction temperature rating.

Part Context

This part belongs to the LB1909 series of motor drivers from onsemi. It shares architectural similarities with other members like the LB1830M but offers higher current capacity and a wider voltage range. The series utilizes BCD technology for efficient power management. It is positioned as a cost-effective solution for embedded motor control tasks in consumer electronics.

Replacement Considerations

Check for direct pin-to-pin replacements within the LB1909 family. Verify if upgraded variants with enhanced thermal performance are available. Cross-reference electrical parameters such as saturation voltage and standby current when considering alternative manufacturers. Ensure the replacement maintains the same 10-MFPS package outline for mechanical compatibility.
