When coupled with external power • Latched Soft Start MOSFETs or Darlingtons, these devices perform fixed-frequency PWM motor control in 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 10 V and 18 V, the UC1625 controls higher • Tachometer voltage power devices with external level-shifting • Trimmed Reference Sources 30 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 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.
