DESCRIPTION

· The A4955 is a full-bridge PWM gate driver designed for DC motor control.

· It operates at up to 50V and drives an all N-channel MOSFET bridge.

· Features internal synchronous rectification for reduced power dissipation.

· Includes multiple protection features: VDS protection, thermal shutdown, undervoltage monitoring, and crossover-current protection.

· Available in 20-pin QFN and eTSSOP packages with exposed thermal pads.

FEATURES

· Standard IN1/IN2 control logic for motor speed and direction.

· Adjustable off-time, blank-time, current limit, and gate drive.

· Overcurrent indication and internal UVLO.

· Voltage output proportional to load current.

· Synchronous rectification and MOSFET VDS protection.

APPLICATIONS

· PWM control of DC motors.

· Suitable for systems requiring efficient motor control with protection features.

· Ideal for applications needing adjustable current and gate drive parameters.
