Import - High Output Current Two Coil Fan Driver - Supplier [Wekeway]

The US890/US891 series is a two coil DC motor andFan driver. It includes a Hall sensor, a dynamic bias calibration circuit, and an output driver with a peak output current of up to 1200mA. It is specially designed to drive large fans and is particularly suitable for low-voltage starting. It also has a frequency generator (FG) or rotation detection (RD) output. And itCollector open circuitOutput makes it easier to interface with external circuits.

Main features:

The peak current can reach 1200mA

● Low starting voltage

● Ground output resistance

● High sensitivity Hall sensor

● Rotor lock protection and automatic restart function

● Built in output protection clamp diode

● Output of speed with protection (US890) or alarm signal (US891)
