Overview
The US91AEZE-AAA-000-RE is a two-coil fan driver from the US91A series, designed for brushless DC motor control. It operates on a supply voltage range of 4.7 V to 30 V with a maximum output current of 250 mA and a typical operating supply current of 2 mA. The device features two outputs and supports load voltages of 12 V or 24 V, with an output voltage rating of 100 V. It functions within a temperature range of -40°C to +125°C and is housed in an SOT-23-5 package.
Feature Summary
- Integrated Hall IC for fan driver applications
- Built-in frequency generator functionality
- Supports two-coil BLDC motor configurations
- Open/switch interface control
Applications
- Fan motor drivers
- Brushless DC motor control
- Two-coil fan systems
Procurement Notes
Verify component status as it may be marked not recommended for new designs due to minimum order quantity restrictions. Confirm package type matches SOT-23-5 specifications. Ensure supply voltage requirements align with the 4.7 V to 30 V operational range. Check RoHS compliance documentation before integration.
Selection Notes
Select this component for low-power two-coil fan applications requiring integrated sensing. Compare against single-coil alternatives if higher current capacity is needed. Verify thermal performance within the specified -40°C to +125°C junction temperature range. Consider the SOT-23-5 footprint constraints during PCB layout design.
Part Context
This part belongs to the US90A/US91A family of motor controllers. It serves as a specialized solution for simple fan driving tasks where integrated Hall sensing reduces external component count. It complements more complex LIN-based drivers by offering a direct open/switch interface for basic speed control applications.
Replacement Considerations
Check for MLX90411 variants if single-coil operation or higher current (up to 1A) is required. Verify compatibility with US90AEZE-AAA-000-RE if different voltage ratings are needed.
