The UC1625, UC2625 and UC3625 are three high-performance brushless DC motor controllers that integrate most of the functions required for high-performance brushless DC motor control into one package. When coupled with external power MOSFETs or Darlingtons, these ICs perform fixed-frequency PWM motor control in either voltage or current mode while implementing closed loop speed control and braking, with smart noise rejection, safe direction reversal, and cross-conduction protection. Although specified for operation from power supplies between 10V and 18V, the UC1625 can control higher voltage power devices with external level-shifting components. The UC1625 contains fast, high-current push-pull drivers for low-side power devices and 50V open-collector outputs for high-side power devices or level shifting circuitry. The UC1625 is characterized for operation over the military temperature range of -55°C to +125°C, while the UC2625 is characterized from -40°C to +105°C and the UC3625 is characterized from -40°C to +85°C.
