The A4956GLPTR-T is a Smart Low-Side Power MOSFET and IGBT Gate Driver, specially designed to work with Arduinos and other microcontrollers. It is primarily used in the motion control industry, such as in drives and stepper motors, and is a perfect choice for other motor control applications. It is suitable for driving both N-channel MOSFET switches and IGBT power transistors with low on-state voltage drop. The A4956GLPTR-T has built-in protection, and it is also fault-protected.

The A4956GLPTR-T is designed for driving both low and high power discrete Mosfets and IGBTs in hard switching applications. Key features include: adjustable deadtime (down to 300 ns minimum); adjustable current limitation; temperature fold back; over-voltage protection (OVP) and under voltage protection (UVP) of the logic supply; a low-output voltage drop of 0.2 V; a 3.3 V logic input and a 6 V to 28 V powered gate drive. Its built-in startup/soft-start circuit eliminates power sequencing requirements. The A4956GLPTR-T also includes an adjustable overload and over-temperature protection.

The A4956GLPTR-T works in tandem with a logic input and the gate-source voltage (Vgs) to control the switching of the power transistor. It provides the gate-source voltage with adjustable peak current, deadtime and fast-recovery gate drive signal. This signal is optimized for low-frequency power conversion applications and ensures a minimum drive signal distortion. Its low voltage drop reduces dynamic power losses. It also has built-in protection circuit to prevent reverse-current backflow.

The A4956GLPTR-T is an ideal device for driving power transistors in applications such as AC inverter drives, brushed DC motor control and stepper motor control. It is an excellent choice for battery powered motor drives, as its high switching speed helps minimize power losses and minimize battery drain. When used alongside an appropriately chosen motor and motor control system, the A4956GLPTR-T can accurately and reliably control the speed and position of the motor.

In summary, the A4956GLPTR-T is an ideal power MOSFET and IGBT gate driver for applications such as motor control, AC inverter drives, and stepper motor control. Its adjustable deadtime, adjustable current limit, adjustable overload and over-temperature protection make it a great choice for applications that need reliable, accurate and low-loss power control. The low voltage drop also helps keep power consumption to a minimum, ensuring longer battery life for battery-powered applications.
