FD128MX/FD128NX
Single Phase Smart DC Motor Driver IC
General Description
The FD128 series is a direct PWM drive IC with single-phase and bipolar drive. The
IC is suitable for variable speed control Fan of PC.
Features
Single-phase coil driver, applied to fan or motor.
Lock function built-in and a lock detect output signal (RD).
Thermistor or PWM modes are available for speed control.
An external capacitor (CO) is necessary for lock function.
An external capacitor (CP = 47pf) for internal 25KHz saw-tooth wave
Thermal Shutdown built-in.
Hall IC input (INN) can use as rotation output (FG)

Single Phase Smart DC Motor Driver IC
1. Input PWM signal by Vset pin
The slowest rotational speed is limited, it is unable to totally stop operating.
2. Input PWM signal by CP pin
The slowest rotational speed is not limited , can totally stop operating
Note: Circuit of using that please watch the application circuits.
