Overview
The LB1923M-TLM-E is a three-phase brushless DC motor pre-driver manufactured by onsemi. It operates within a supply voltage range of 4.4 V to 7 V and functions as a half-bridge driver. The component supports surface mount installation in a reel or cut tape format. It is rated for an operating temperature range from -20°C to +80°C. The device weighs approximately 500 mg and is classified under PMIC power management ICs.
Feature Summary
- Provides pre-driver functionality for three-phase brushless DC motors
- Integrates half-bridge output configuration
- Supports bidirectional control and commutation management
Applications
- Brushless DC motor control systems
- Three-phase motor drive circuits
- Motion control applications requiring pre-driver stages
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, with some major distributors indicating no current sales in certain regions. Verification of lifecycle status and substitute part numbers is required before integration into new designs due to discontinuation.
Selection Notes
Designers should evaluate this part against active alternatives given its discontinued status. The low voltage operation between 4.4 V and 7 V limits suitability for higher voltage systems. Verify package compatibility and thermal performance within the specified -20°C to +80°C range for the target application environment.
Part Context
The LB1923M-TLM-E belongs to the LB1923M series of motor controllers. It is designed specifically for driving three-phase BLDC motors using a pre-driver architecture. The TLM suffix indicates the specific tape and reel packaging variant offered by onsemi for surface mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, engineers must identify functional equivalents independently based on pinout, voltage ratings, and interface requirements.
