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
