LB11922-TLM-E Equivalent & Substitute Parts

Part Overview

The LB11922-TLM-E is a Brushless DC (BLDC) motor driver controller manufactured by onsemi, designed for general-purpose applications requiring commutation and direction management functions. Operating within a 4.4V to 7V supply voltage range, this device integrates three pre-driver half-bridge outputs in a 36-SSOP surface-mount package.

The LB11922-TLM-E carries an Obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support, production continuity, and system maintenance. Substitute parts must maintain core functional capabilities while accommodating differences in supply voltage ranges, package configurations, and interface specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB11922-TLM-E is determined by the following critical parameters:

• Motor Control Function: All substitutes must provide BLDC motor commutation and direction management via pre-driver half-bridge outputs (3 outputs minimum)
• Interface Type: Parallel interface operation is required for direct compatibility
• Supply Voltage Range: Substitutes must operate within or encompass the 4.4V to 7V supply window, or operate at higher voltage ranges suitable for step-down regulation in the application circuit
• Package Configuration: Surface-mount packages with compatible pinout and thermal characteristics
• Output Stage Architecture: Pre-driver half-bridge configuration supporting three independent motor phases

The substitute parts identified—BD62012FS-E2, BD62013FS-E2, BD6761FS-E2, and BD6762FV-E2—satisfy these functional requirements while operating at elevated supply voltages (10V–18V and 16V–28V ranges). These parts maintain identical motor control topology and output stage configuration, enabling functional substitution in applications where supply voltage can be accommodated through circuit design modifications.

Engineering Selection Recommendations

LB11923V-A-TLM-E (onsemi): This part represents the primary equivalent within the onsemi product family. It maintains BLDC motor control functionality with both parallel and PWM interface capability. The device carries Active product status and ROHS3 compliance, providing long-term design support and regulatory alignment. Inventory availability (1267 units) supports production requirements. Selection of this part eliminates supply voltage range concerns while maintaining manufacturer continuity.

BD62013FS-E2 (Rohm Semiconductor): This parallel-interface motor driver operates at 10V–18V supply voltage and provides identical three-phase pre-driver half-bridge output architecture. The part carries Not For New Designs status but maintains ROHS3 compliance and unlimited MSL rating. This substitute is suitable for applications where supply voltage elevation through circuit design is feasible. Current inventory (890 units) supports near-term production needs.

BD6761FS-E2 (Rohm Semiconductor): Operating at 16V–28V supply voltage, this device provides parallel-interface BLDC motor control with Active product status and ROHS3 compliance. The 32-SSOP package accommodates the three-phase pre-driver architecture. Unlimited MSL rating and substantial inventory (5200 units) support production continuity and long-term availability. This part is suitable for higher-voltage system architectures.

BD6762FV-E2 (Rohm Semiconductor): This 40-SSOP parallel-interface motor driver operates at 16V–28V supply voltage with Active product status and ROHS3 compliance. The expanded package provides additional pin count for enhanced system integration. Unlimited MSL rating and high inventory (8480 units) ensure supply security. Selection is appropriate for applications requiring higher voltage operation and expanded I/O capability.

BD62012FS-E2 (Rohm Semiconductor): This PWM-interface motor driver operates at 10V–18V supply voltage. The Not For New Designs status and PWM-only interface (versus parallel) limit its suitability as a direct substitute. This part is retained for reference in legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can the LB11922-TLM-E be directly replaced with a higher-voltage substitute without circuit modification?

A: Direct replacement without circuit modification is not possible. The LB11922-TLM-E operates at 4.4V–7V supply voltage, while all identified substitutes operate at 10V–18V or 16V–28V. System power supply architecture must be modified to accommodate the substitute part's voltage requirements, typically through addition of a step-down regulator or redesign of the power distribution network.

Q: What is the functional difference between parallel and PWM interface motor drivers?

A: Parallel interface devices accept commutation and direction control signals through dedicated logic-level input pins, enabling direct microcontroller integration. PWM interface devices modulate motor speed through pulse-width modulation of the supply voltage or gate drive signals. The LB11922-TLM-E requires parallel interface operation; BD62012FS-E2 operates in PWM mode only and is not functionally equivalent for direct substitution.

Q: Are all substitute parts RoHS and REACH compliant?

A: All identified substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. The original LB11922-TLM-E carries REACH Unaffected status but predates RoHS3 certification. Substitution with ROHS3-compliant parts ensures regulatory alignment for new production.

Q: What is the significance of MSL (Moisture Sensitivity Level) rating differences?

A: The LB11922-TLM-E carries MSL 3 rating (168-hour floor life), requiring controlled storage and handling procedures. All substitute parts carry MSL 1 rating (unlimited floor life), eliminating moisture sensitivity constraints during manufacturing and storage. This represents an improvement in supply chain handling and production flexibility.

Q: Which substitute part provides the closest functional match to the LB11922-TLM-E?

A: LB11923V-A-TLM-E provides the closest functional match, maintaining onsemi manufacturer continuity, parallel interface operation, and BLDC motor control architecture. Active product status ensures long-term design support and availability. This part is the recommended primary substitute for applications where supply voltage can be accommodated through circuit design.

Q: Can multiple substitute parts be used interchangeably within a single product line?

A: Interchangeability depends on system power supply architecture and PCB layout constraints. Parts operating at different voltage ranges (10V–18V versus 16V–28V) require separate power supply designs. Package differences (24-SSOP, 32-SSOP, 40-SSOP) necessitate distinct PCB layouts. Within a single product line, standardization on one substitute part is recommended to minimize design and manufacturing complexity.

Q: What inventory considerations apply to substitute part selection?

A: Current inventory levels vary significantly: LB11923V-A-TLM-E (1267 units), BD62013FS-E2 (890 units), BD6761FS-E2 (5200 units), and BD6762FV-E2 (8480 units). For production programs requiring sustained component supply, parts with higher inventory and Active product status (BD6761FS-E2, BD6762FV-E2) provide greater supply security. Parts with Not For New Designs status should be reserved for legacy system maintenance only.
