The servomotor case contains a gearhead motor, a small motor driver circuit, and a potentiometer used to measure the position of the output shaft. Often the circuit consists of a single chip and a few transistors, resistors, and capacitors. The H-bridge handles the high current required to drive the motor. (Darren SAWICZ, "Hobby Servo Fundamentals" [28] ). The chip in a servomotor case is often  a Mitsubishi M51660L, RS ZN409 / GEC PLESSEY ZN409CE, KC2462 to KC8801, NE544, NJM2611, MC33030, etc. [29] [30]
