LB11967V-TLM-E Equivalent & Substitute Parts

Part Overview

The LB11967V-TLM-E 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-E 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 functional equivalence in BLDC motor driver capability, PWM interface support, and half-bridge output configuration, despite differences in package pin count and specific output stage integration levels.

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-E. Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

BD69740FV-GE2 provides the closest functional match to the LB11967V-TLM-E, offering PWM interface control and half-bridge (2) output configuration identical to the original specification. This device operates across a 4.3V ~ 17V supply range, which encompasses the original 6V ~ 16V requirement.

BD69730FV-GE2 offers extended half-bridge output capability (4 bridges) with logic-level interface control and operates across the same 4.3V ~ 17V supply range. This device provides additional output stage flexibility for applications requiring expanded motor control capability.

Both substitutes feature improved moisture sensitivity ratings (MSL 1 vs. MSL 3) and extended operating temperature ranges (-40°C ~ 105°C vs. -30°C ~ 95°C), providing enhanced reliability margins in production and field deployment environments.

Frequently Asked Questions (FAQ)

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

A: BD69740FV-GE2 provides functional equivalence for BLDC motor speed control applications through matching PWM interface and half-bridge (2) output configuration. However, the package transition from 20-LSSOP to 16-LSSOP requires PCB layout modification. Pin-to-pin correspondence must be verified against device datasheets before implementation.

Q: What is the primary difference between the two substitute options?

A: BD69740FV-GE2 maintains PWM interface control matching the original LB11967V-TLM-E specification. BD69730FV-GE2 operates with logic-level interface control and provides four half-bridge outputs instead of two, offering expanded motor control capability for multi-motor or higher-complexity applications.

Q: Are there supply voltage compatibility concerns with the substitutes?

A: Both substitutes operate across 4.3V ~ 17V, which fully encompasses the original 6V ~ 16V specification. No voltage compatibility issues exist for applications within the original supply range.

Q: How do package differences affect board-level implementation?

A: The original LB11967V-TLM-E uses 20-LSSOP packaging, while both substitutes use 16-LSSOP packaging. Both packages maintain identical 0.173" width and 4.40mm body dimensions, but pin count reduction requires complete PCB footprint redesign and signal routing verification.

Q: What compliance advantages do the substitute parts offer?

A: Both BD69730FV-GE2 and BD69740FV-GE2 maintain ROHS3 compliance and REACH unaffected status. Additionally, both feature MSL 1 moisture sensitivity rating compared to MSL 3 for the original part, reducing moisture-related field failures and enabling extended storage without baking requirements.
