Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB11923V-TLM-E is determined by strict alignment of the following critical parameters:

• Motor Control Function: Brushless DC (BLDC) commutation and direction management capability
• Output Configuration: Pre-driver half-bridge topology with three output stages
• Interface Protocol: PWM-based control input
• Supply Voltage Range: 4.4V to 7V operation
• Package Compatibility: 44-LSSOP surface mount form factor
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Moisture Sensitivity: MSL 3 rating (168 Hours)

The LB11923V-A-TLM-E qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while maintaining the same base product number (LB11923) and regulatory certifications.
