Overview
The A4915METTR-T is a three-phase MOSFET pre-driver integrated circuit manufactured by Allegro MicroSystems. It operates with a supply voltage range of 3V to 5.5V and supports load voltages from 5V to 50V. The device is housed in a 28-QFN (5x5mm) package with an exposed pad for thermal management. It is designed for brushless DC motor applications, featuring parallel interface control. The component functions within a junction temperature range of -20°C to 150°C.
Feature Summary
- Integrates high-side and low-side pre-drivers for three-phase power stages
- Includes built-in dead-time generation to prevent shoot-through
- Provides overcurrent protection via internal comparators
- Supports bootstrap operation for high-side gate driving
Applications
- Brushless DC (BLDC) motor drives
- General-purpose motor control systems
- Three-phase power stage interfaces
Procurement Notes
Verify the specific suffix METTR against official datasheets to confirm the 28-QFN package and tape-and-reel packaging configuration. Ensure compatibility with system voltage requirements, as the device specifies a 3V to 5.5V supply range. Confirm that the 5V to 50V load voltage rating aligns with the target motor application before procurement.
Selection Notes
Select this component when a compact solution for three-phase BLDC control is required. The 28-QFN package offers a small footprint suitable for space-constrained designs. Consider the operating temperature range and thermal dissipation capabilities of the exposed pad for high-power applications. Verify interface compatibility with the host microcontroller for parallel control signals.
Part Context
This part belongs to the A4915 family of three-phase MOSFET controller ICs from Allegro MicroSystems. The family provides integrated solutions for driving power MOSFETs in motor applications. The METTR variant specifically denotes the QFN package and reel packaging format, distinguishing it from other pinout or package options within the same functional series.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for direct replacements or cross-reference compatible devices based on pinout and electrical specifications.
