UC2625N Datasheet

Motor / Motion / Ignition Controllers & Drivers


The UC2625N family of motorcontroller devices 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 devices 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 10 V and 18 V, the UC1625 controls 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. UC2625N Features • Drives Power MOSFETs or Power Darlingtons Directly• 50-V Open Collector High-Side Drivers• Latched Soft Start• High-Speed Current-Sense Amplifier with Ideal Diode• Pulse-by-Pulse and Average Current Sensing• Over-Voltage and Under-Voltage Protection • Direction Latch for Safe Direction Reversal• Tachometer• Trimmed Reference Sources 30 mA• Programmable Cross-Conduction Protection• Two-Quadrant and Four-Quadrant Operation
