LB11967V-TLM-H Equivalent & Substitute Parts

Part Overview

The LB11967V-TLM-H is a motor driver IC manufactured by onsemi, designed for brushless DC (BLDC) motor speed control applications. This device operates across a 6V to 16V supply range and features PWM interface control with pre-driver half-bridge output configuration in a 20-SSOP package. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB11967V-TLM-H is determined by the following critical parameters:

• Motor type compatibility: Brushless DC (BLDC) motor support
• Control interface: PWM-based speed control capability
• Output stage configuration: Half-bridge driver topology
• Supply voltage range: Minimum overlap with 6V ~ 16V specification
• Package compatibility: Surface mount LSSOP family
• Regulatory compliance: ROHS3 and REACH status alignment

The substitute parts BD69730FV-GE2 and BD69740FV-GE2 meet these criteria through their BLDC motor driver functionality, PWM interface support, half-bridge output configuration, and compatible supply voltage ranges (4.3V ~ 17V). Both devices maintain ROHS3 compliance and surface mount packaging in the 16-LSSOP form factor.

Parameter Comparison

Engineering Selection Recommendations

Both BD69730FV-GE2 and BD69740FV-GE2 are active products from Rohm Semiconductor with extended product lifecycle support compared to the obsolete LB11967V-TLM-H. Selection between these alternatives depends on specific application requirements:

BD69740FV-GE2 maintains closer functional alignment with the original LB11967V-TLM-H through its PWM interface and pre-driver half-bridge (2) output configuration, making it the primary substitute for direct replacement in speed control applications.

BD69730FV-GE2 offers expanded output capability with half-bridge (4) configuration and logic-level interface, suitable for applications requiring enhanced driver integration. This device provides superior moisture handling with MSL 1 rating versus the original MSL 3 specification.

Both substitutes support the full supply voltage range of the original device and exceed the operating temperature range, providing enhanced thermal margin. ROHS3 compliance and REACH unaffected status are maintained across all three devices.

Frequently Asked Questions (FAQ)

Q: Can BD69740FV-GE2 directly replace LB11967V-TLM-H in existing designs?

A: BD69740FV-GE2 is functionally compatible for BLDC motor speed control applications. Both devices feature PWM interface control and half-bridge (2) output configuration. Pin-to-pin compatibility must be verified against specific PCB layout and schematic requirements, as package pin counts differ (20-SSOP versus 16-SSOP-B).

Q: What is the primary difference between BD69730FV-GE2 and BD69740FV-GE2?

A: BD69730FV-GE2 features half-bridge (4) output configuration with logic-level interface, providing expanded driver capability. BD69740FV-GE2 maintains half-bridge (2) configuration with PWM interface, offering closer functional alignment to the original LB11967V-TLM-H for speed control applications.

Q: Are package dimensions compatible between the original and substitute parts?

A: All three devices use LSSOP surface mount packages with 0.173" width and 4.40mm body width. The original LB11967V-TLM-H uses 20-SSOP packaging, while both substitutes use 16-SSOP-B packaging. PCB footprint redesign is required for implementation.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. BD69730FV-GE2 and BD69740FV-GE2 are both ROHS3 compliant and REACH unaffected, matching the regulatory status of LB11967V-TLM-H. Both substitutes offer improved moisture sensitivity ratings (MSL 1 versus MSL 3).

Q: What is the supply voltage overlap between the original and substitute parts?

A: The original LB11967V-TLM-H operates at 6V ~ 16V. Both substitutes operate at 4.3V ~ 17V, providing full compatibility within the original specification range with extended lower and upper voltage margins.
