Brushless DC Motor Controller  
FEATURES  
DESCRIPTION  
• Drives Power MOSFETs or Power Darlingtons The UC3625 family of motor controller ICs integrate most of the  
Directly  
functions required for high-performance brushless DC motor con-  
trol 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.  
• 50V Open Collector High-Side Drivers  
• Latched Soft Start  
• High-speed Current-Sense Amplifier with Ideal  
Diode  
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.  
• Pulse-by-Pulse and Average Current Sensing  
• Over-Voltage and Under-Voltage Protection  
• Direction Latch for Safe Direction Reversal  
• Tachometer  
The UC1625 is characterized for operation over the military tem-  
perature range of –55°C to +125°C, while the UC2625 is charac-  
terized from –40°C to +105°C and the UC3625 is characterized  
from 0°C to 70°C. (NOTE: ESD Protection to 2kV)  
• Trimmed Reference Sources 30mA  
• Programmable Cross-Conduction Protection  
• Two-Quadrant and Four-Quadrant Operation
