The A4956GESTR-T from Allegro Microsystems is a versatile Full-Bridge PWM Gate Driver engineered for precise control of DC motors. It supports operation up to 50V and provides gate drive for an all N-channel external MOSFET bridge, enabling efficient speed and direction control through externally applied PWM signals.
Key features include internal synchronous rectification for reduced power dissipation, adjustable current limit, adjustable off-time and blank-time, and selection for decay modes. The device incorporates robust internal circuit protection, including VDS protection, thermal shutdown with hysteresis, undervoltage monitoring of VBB, and crossover-current protection, ensuring reliable operation.
Supplied in a compact 20-pin QFN (4x4mm) package with an exposed thermal pad, the A4956GESTR-T is designed for surface mounting. Its input terminals facilitate easy integration with PWM control signals for motor speed and direction management, making it suitable for general-purpose applications requiring robust motor control.
This gate driver is designed for applications requiring advanced control and protection for brushed DC motors. Its comprehensive feature set and integrated protection mechanisms make it a reliable choice for various motor control systems.
