Overview
The LB1838M-TRM-E is a monolithic digital integrated circuit functioning as a low-saturation, two-channel bidirectional motor driver. Designed for low-voltage applications, it serves as a bipolar stepper-motor driver IC suitable for printers, cameras, and portable devices. The device operates with a minimum supply voltage of 2.5V and features a low saturation voltage of 0.40V at 400mA. It incorporates built-in through-current prevention, separate logic and motor power supplies, spark killer diodes, and a thermal shutdown circuit.
Feature Summary
- Low-saturation two-channel bidirectional motor driver design
- Built-in through-current prevention and thermal shutdown circuits
- Separate logic and motor power supply architecture
- Integrated spark killer diodes
Applications
- Printers
- Cameras
- Portable devices
Procurement Notes
Verify the specific suffix TRM-E against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with the LB1838 base product family specifications. Confirm RoHS3 compliance and REACH status prior to integration. Cross-reference absolute maximum ratings with system operating conditions to prevent overstress.
Selection Notes
Select this component for low-voltage bipolar stepper motor control in compact electronics. The separate logic and motor power supplies simplify interface design. Built-in protection features reduce external component count. Verify that the required current does not exceed the specified saturation limits under expected thermal conditions.
Part Context
This part belongs to the LB1838 series of motor drivers from onsemi. It is specifically packaged in a 14-pin MFP-14 lead-free package. The device is categorized under signal circuits and power management solutions for motor control applications within the manufacturer's portfolio.
Replacement Considerations
LB1838MEVB is an evaluation board for the LB1838M, not a direct functional substitute. No other public substitute part numbers are confirmed for this specific model.
