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.

(1) Currents are positive into and negative out of the specified terminal.
(2) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only and functional operation of the device at these or any other conditions beyond
those specified is not implied.
