A4936METTR-T

Overview

The A4936METTR-T is a three-phase brushless DC (BLDC) motor driver IC manufactured by Allegro MicroSystems. It operates within a supply voltage range of 8.5V to 37.5V and features a 32-VFQFN exposed pad package measuring 5x5 mm. The device integrates pre-drivers for three half-bridge outputs and supports PWM interface control. Designed for general applications, it includes built-in controller functions for commutation and direction management. The component is rated for an operating temperature range from -20°C to +105°C.

Feature Summary

Integrates pre-drivers for three half-bridge outputs to support BLDC motor control
Provides internal controller functions for automatic commutation and direction management
Supports PWM interface for external control signal input

Applications

Brushless DC (BLDC) motor control systems
General purpose motor driver applications
Industrial automation equipment requiring precise motor direction management

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm that the 32-QFN(5x5) package matches the target PCB footprint requirements. Ensure the 8.5V to 37.5V supply voltage range aligns with the system power design. Check current status as this part may be subject to discontinuation notices.

Selection Notes

Select this component when a dedicated BLDC driver with integrated commutation logic is required. The 32-pin QFN package offers a compact solution for space-constrained designs. Verify that the 37.5V maximum voltage rating suits the motor bus voltage. Consider the -20°C to +105°C operating temperature range for environmental suitability.

Part Context

The A4936 belongs to Allegro's family of stepper and BLDC motor driver integrated circuits. This specific model targets three-phase brushless motors, distinguishing it from bipolar stepper drivers in the same series. It provides a complete control solution by combining gate driving capabilities with logical commutation sequencing.
