无刷子的DC马达控制器(英文)(pdf 14页)

DESCRIPTION
The UC3625 family of motor controller ICs 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 0°C to 70°C. (NOTE: ESD Protection to 2kV)……
