Overview
The ZXBM1021Q20TC is a single-phase brushless DC motor pre-driver from Diodes Incorporated, designed for speed control in cooling fans and pumps. It operates within a voltage range of 6.8V to 18V, supporting direct 12V motors or higher voltages via external regulation. The device integrates PWM signal integration, MOSFET buffering, and Hall effect sensor biasing circuits. It features high-side and low-side drive outputs with specific current capabilities to manage external H-bridge switches without additional buffering.
Feature Summary
- Integrates PWM signal integrator and MOSFET buffer to simplify system architecture
- Includes Hall effect sensor bias and amplifier circuits for broad compatibility
- Features programmable overcurrent protection and soft-start functionality
Applications
- Cooling fans in consumer and industrial products
- Exhaust fans and ventilation systems
- Electric motors and pump applications
Procurement Notes
Verify the specific suffix 'Q20TC' against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure the component meets required automotive or industrial qualification standards if applicable to the target application environment.
Selection Notes
Select this component when space constraints require an integrated solution that reduces external passive components. It is suitable for designs needing flexible input control via PWM, DC voltage, or thermistor networks while requiring robust protection against rotor lockup and thermal damage.
Part Context
This part belongs to the ZXBM series of motor pre-drivers, which focus on simplifying BLDC motor control by integrating common external elements. The series supports various motor types and provides comprehensive protection features essential for reliable operation in constrained environments.
Replacement Considerations
Check for ZXBM1021 variants with different suffixes for package differences. Verify functional equivalence with other single-phase BLDC pre-drivers if supply chain constraints exist.
