LB11850VA-MPB-E

Overview

The LB11850VA-MPB-E is a dual-channel DC motor driver IC manufactured by onsemi. It integrates two H-bridge drivers capable of delivering continuous output currents up to 2.5 A per channel with peak currents reaching 3.5 A. The device operates within a supply voltage range of 4.5 V to 16 V and supports PWM frequencies up to 100 kHz. Key features include built-in short-circuit protection, thermal shutdown, and low standby current. It is housed in a 20-pin SSOP package designed for compact applications requiring efficient motor control.

Feature Summary

• Integrates dual H-bridge circuits for independent control of two DC motors or one stepper motor
• Includes comprehensive protection mechanisms such as thermal shutdown and short-circuit detection
• Supports high-frequency PWM input signals for precise speed and direction regulation
• Features low quiescent current mode to minimize power consumption during standby

Applications

• Home appliance motor control systems
• Office automation equipment drive circuits
• Industrial servo and actuator modules
• Robotics joint movement controllers

Procurement Notes

Verify the specific suffix 'MPB-E' against the latest onsemi datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel quantity if applicable. Cross-reference with official distributors to confirm current availability and lifecycle status, as automotive or industrial grades may have different lead times.

Selection Notes

Select this component when designing systems requiring dual-motor control with moderate current demands under 2.5 A continuous load. It is suitable for applications where board space is limited due to its integrated H-bridge topology. Consider external heat sinking if operating near maximum current limits in enclosed environments. Verify input voltage compatibility with the system's power rail before integration.

Part Context

This part belongs to onsemi's LB118xx series of dual DC motor drivers. These devices are widely used in consumer electronics and industrial automation for their reliability and ease of interface with microcontrollers. The series offers various package options to suit different thermal and spatial constraints while maintaining consistent electrical performance characteristics across the family.

Replacement Considerations

Check for direct pin-compatible alternatives within the LB118xx series or comparable offerings from other manufacturers like Toshiba or STMicroelectronics. Ensure replacement parts match the voltage range, current capacity, and protection features. Verify that any substitute maintains the same control logic levels and package dimensions for seamless retrofitting.
