Working Principles

The L6229D is a power DMOS full bridge driver designed for controlling DC motors. It utilizes integrated power DMOS transistors to drive the motor with high voltage capability. The device operates by receiving input signals (IN1, IN2, IN3, IN4) that control the direction and speed of the motor. These signals are amplified and used to drive the corresponding outputs (OUT1, OUT2, OUT3, OUT4) which control the motor phases.

The charge pump circuitry generates the necessary voltage levels for driving the high-side N-channel MOSFETs, allowing the use of low-cost components. The built-in protection features such as thermal shutdown and overcurrent protection ensure safe operation and prevent damage to the device and motor.
