DESCRIPTION/ORDERING INFORMATION

The UC1625 motor controller integrates most of the functions required for high-performance brushless dc motor

control into one package. When coupled with external power MOSFETs or Darlingtons, this device performs

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 10 V and 18 V, 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 50-V 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.
