AMT49106 Overview
Key Specifications
Description
The AMT49106 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a 3-phase bridge arrangement and is specifically designed for automotive applications with high-power inductive loads, such as BLDC motors. A unique charge pump regulator provides the supply for the MOSFET gate drive for battery voltages down to 5.5 V and allows the AMT49106 to operate with a reduced gate drive down to 4.5 V.
Key Features
- 3-phase bridge MOSFET driver
- Bootstrap gate drive for N-channel MOSFET bridge
- Cross-conduction protection with adjustable dead time
- Charge pump for low supply voltage operation
- Strong VREG charge pump to support up to 40 mA average gate switching current, enables driving 330 nC external MOSFETs at 20 kHz
