1FEATURES DESCRIPTIONThe UC3625 family of motorcontroller devices
• Drives Power MOSFETsor Power Darlingtons integrate most of the functions required for high-
Directly performance brushless dc-motor control into one
• 50-V Open Collector High-Side Drivers package. When coupled with external power
Latched Soft Start MOSFETs or Darlingtons, these devices perform
fixed-frequency PWM motor controlin either voltage
• High-Speed Current-Sense Amplifier with Ideal or current mode while implementing closed-loop
Diode speed control and braking with smart noise rejection,
• Pulse-by-Pulse and Average Current Sensing safe direction reversal, and cross–conduction
Over-Voltage and Under-Voltage Protection protection.
Direction Latch for Safe Direction Reversal Although specified for operation from power supplies
between 10V and 18V, the UC1625 controls higher
• Tachometervoltage power devices with external level-shifting
• Trimmed Reference Sources30 mA components. The UC1625 contains fast, high-current
• Programmable Cross-Conduction Protection push-pull drivers for low-side power devices and 50-V
Two-Quadrant and Four-Quadrant Operation open-collector outputs for high-side power devicesor
level-shifting circuitry.
The UC1625is characterized for operation over the
military temperature rangeof –55°Cto +125°C, while
the UC2625is characterized from –40°Cto +105°C
and the UC3625is characterized from 0°Cto +70°C.
