Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB11872H-TLM-E is determined by the following critical parameters:

Functional Requirements:

• Motor driver type: Brushless DC (BLDC)
• Output configuration: Half Bridge (3)
• Interface: Parallel control
• Fully integrated control and power stage

Electrical Compatibility:

• Supply voltage range must encompass or exceed 10V ~ 28V
• Output current capability must meet or exceed 1.2A
• Load voltage range must accommodate 10V ~ 28V operation

Physical & Environmental:

• Surface mount technology
• Operating temperature range must support -20°C ~ 85°C minimum
• Moisture sensitivity level 3 or better

The LV8112VB-AH qualifies as a substitute based on these criteria, offering enhanced specifications across multiple parameters while maintaining functional equivalence for BLDC motor driver applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LB11872H-TLM-E and LV8112VB-AH are classified as obsolete products. Selection between these devices should be based on the following engineering criteria:

LB11872H-TLM-E remains the preferred choice for applications with strict form factor constraints, as its 28-pin package occupies less board space than the LV8112VB-AH 44-pin alternative.

LV8112VB-AH is suitable for applications requiring enhanced performance margins. The substitute offers increased output current (2.5A versus 1.2A), extended supply voltage range (10V ~ 35V versus 10V ~ 28V), and wider operating temperature range (-25°C ~ 150°C versus -20°C ~ 85°C). The Bi-CMOS technology provides lower power consumption characteristics compared to the bipolar implementation of the main part.

Both devices maintain identical compliance status (REACH Unaffected, EAR99 classification, HTSUS 8542.39.0001) and equivalent moisture sensitivity levels. PCB layout modifications are required due to package differences (28-SOP versus 44-LSSOP).

Frequently Asked Questions (FAQ)

Q: Can the LV8112VB-AH directly replace the LB11872H-TLM-E without PCB modifications?

A: No. The LV8112VB-AH uses a 44-pin LSSOP package versus the 28-pin SOP package of the LB11872H-TLM-E. Pin assignments differ, requiring PCB layout redesign and schematic updates. However, the functional interface (parallel control, half-bridge output configuration) remains compatible.

Q: What are the key electrical differences between these devices?

A: The LV8112VB-AH provides higher output current (2.5A versus 1.2A), extended supply voltage range (35V maximum versus 28V), and wider operating temperature range (-25°C to 150°C versus -20°C to 85°C). The LB11872H-TLM-E uses bipolar technology while the LV8112VB-AH employs Bi-CMOS technology.

Q: Are both parts still available for procurement?

A: Both devices are classified as obsolete. Availability is limited to existing inventory. The LB11872H-TLM-E has 3300 pieces in stock, while the LV8112VB-AH has 728 pieces available.

Q: Do these devices have different compliance or regulatory requirements?

A: No. Both devices share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8542.39.0001). Moisture sensitivity levels are equivalent (MSL 3, 168 hours).

Q: Which device should be selected for new designs?

A: Since both devices are obsolete, neither is recommended for new designs. Alternative current-production BLDC motor drivers from onsemi or other manufacturers should be evaluated for new applications.
