LB1830M-TLM-E

Overview

The LB1830M-TLM-E is a low-voltage bipolar stepper motor driver manufactured by onsemi. It operates within a supply voltage range of 3V to 9V and delivers an output current of 500mA. The device integrates full control and power stages in a compact 10-MFPS surface-mount package. It supports parallel interface control and functions as a half-bridge driver with two outputs. The component is rated for an operating temperature range from -20°C to 80°C.

Feature Summary

• Integrates complete drive and control circuitry for bipolar stepper motors
• Supports bidirectional operation with built-in braking functionality
• Designed for low-voltage applications with minimal standby current consumption

Applications

• Video equipment motor control
• Portable camera mechanisms
• General-purpose motion control systems

Procurement Notes

Verify the specific suffix 'TLM-E' against official onsemi documentation to confirm pinout compatibility and RoHS status. Confirm that the 10-MFPS package dimensions match the target PCB layout. Check for obsolescence notices, as this part may be discontinued or superseded by newer revisions in the LB1830 series.

Selection Notes

Select this component for applications requiring a single-chip solution for small bipolar stepper motors. Ensure the load current does not exceed 500mA and the supply voltage remains within the 3V to 9V window. Consider thermal management requirements if operating near maximum current limits in enclosed spaces.

Part Context

This part belongs to the LB1830 family of monolithic linear ICs designed for low-voltage motor driving. It replaces older discrete solutions by integrating power transistors and logic control. The TLM-E designation indicates a specific tape-and-reel packaging variant suitable for automated assembly processes.

Replacement Considerations

Check for direct replacements such as the LB1837ML-TLM-E for higher current capabilities or different package options. Verify functional equivalence with other onsemi stepper drivers in the same voltage class before substitution.
