Overview
The A1448EEWLT-P is a fully integrated motor driver manufactured by Allegro MicroSystems, designed for brushless DC (BLDC) motor applications. It operates within a supply voltage range of 1.8V to 4.2V and delivers an output current of 200mA. The device features two half-bridge outputs and utilizes a CMOS technology with an on/off interface. Packaged in a compact 6-DFN/MLP (1.5x2mm) surface-mount format, it supports junction temperatures from -40°C to 165°C. This component integrates both control logic and power stages for efficient tactile feedback systems.
Feature Summary
- Fully integrated design combining control logic and power stage
- Optimized for brushless DC motor drive applications
- Capable of operating across an extended temperature range
Applications
- Tactile feedback systems
- Brushless DC motor control
- Haptic actuators
Procurement Notes
Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors or secondary markets. Ensure that any replacement strategy accounts for the discontinuation notice. Validate that the 6-DFN package dimensions match the target PCB footprint. Check RoHS3 compliance documentation for regulatory requirements.
Selection Notes
Select this part when designing low-voltage BLDC motor drivers requiring high thermal performance. The wide junction temperature range suits demanding environments. The small 6-DFN package aids in space-constrained layouts. Ensure the application voltage remains within the 1.8V to 4.2V specification. Consider the 200mA output limit for load requirements.
Part Context
