Overview
The onsemi LB1638MC-AH is a low-voltage, low-saturation bidirectional motor driver IC designed for driving brushed DC motors in battery-powered applications. It features a half-bridge output configuration capable of delivering up to 500 mA of output current. The device operates within a supply voltage range of 2.5 V to 9 V and has a maximum power dissipation of 820 mW. It functions with an operating supply current of 10 mA and supports a minimum operating temperature of -20°C.
Feature Summary
- Bidirectional control capability for low-voltage motor applications
- Low saturation output characteristics for improved efficiency
- Designed specifically for battery-powered systems
Applications
- Driving brushed DC motors in portable devices
- Battery-powered appliance motor control
- Low-voltage industrial motor drivers
Procurement Notes
Verify the specific suffix 'AH' against the official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your project standards. Cross-reference the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a bidirectional driver is required for small brushed DC motors operating below 9 V. The 500 mA current rating suits light-load applications. Consider thermal management due to the 820 mW power dissipation limit. Verify that the input logic levels are compatible with the controlling microcontroller or system interface.
Part Context
This part belongs to the LB1638MC series of bipolar parallel motor drivers from onsemi. These ICs are engineered for low-voltage environments where low saturation voltage is critical for maintaining efficiency. The series typically includes variants optimized for different packaging or environmental conditions, serving as compact solutions for motion control in consumer electronics.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as other LB1638MC variants. Evaluate generic H-bridge drivers with similar current ratings if specific onsemi features are not strictly required. Ensure any substitute maintains the bidirectional control and low-voltage operation capabilities.
