Overview
The A3932SEQ-T is a three-phase brushless DC motor driver manufactured by Allegro MicroSystems. It integrates power MOSFETs and operates within a supply voltage range of 18V to 50V. The device utilizes a 32-PLCC package with J-leads, measuring 11.43x13.97mm. It supports PWM and parallel interfaces for control. The component functions as a pre-driver with three half-bridge outputs and includes commutation and direction management capabilities. It is rated for an operating temperature range of -20°C to 85°C (TA) and complies with RoHS3 standards.
Feature Summary
- Integrates power MOSFETs for three-phase BLDC motor control
- Provides hardware-based commutation and direction management
- Supports PWM and parallel interface configurations
Applications
- Brushless DC (BLDC) motor drives
- General industrial motor control systems
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging versus other variants like 'SEQ'. Confirm current availability status as listings indicate potential discontinuation. Ensure compliance requirements match the RoHS3 designation found in distributor records. Cross-reference the 32-PLCC footprint dimensions against PCB layout specifications before finalizing procurement decisions.
Selection Notes
Select this component when designing systems requiring integrated three-phase BLDC drive solutions with voltages up to 50V. Consider the 32-PLCC package constraints for thermal management and board space. Verify that the -20°C to 85°C ambient temperature range meets environmental requirements. Evaluate interface compatibility if using parallel or PWM control signals for commutation.
Part Context
This part belongs to the A3932 family of motor drivers from Allegro MicroSystems. Variants such as A3932SEQ and A3932SEQTR-T share similar electrical characteristics but differ in packaging formats. The A3932 series is designed for robust performance in driving three-phase motors without external gate drivers.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Check manufacturer announcements for direct replacements due to the discontinued status indicated in some sources.
