6) CW/CCW Input Terminal (CW)

Rotation direction can be switched with CW terminal. When CW="H" or OPEN, the direction is CW. When CW="L",

the direction is CCW. Though we do not recommend switching rotation direction when motor is rotating, because if

rotation direction is switched when rotating, the rotation speed becomes hall frequency that is up to less than 40Hz

(Typ) and it is switched to the set rotation direction after the action short brake. In addition, CW terminal is pulled up

by VREG through resistance of 100k

Ω (Typ) ±30kΩ.

7) 1FG/3FG Switching Terminal (FGSW)

FG signal that is output from FGO terminal can be switched to 1FG/3FG. It becomes 3FG by FGSW="H" or OPEN,

and 1 FG by FGSW="L". Moreover, FGSW terminal is pulled up by VREG through resistance of 100k

Ω (Typ)±30kΩ.

8) Hall Input (HALL: HUP, HUN, HVP, HVN, HWP, HWN)

Hall input amplifier is designed with hysteresis (±15mV (Typ)) in order to prevent incorrect action due to noise inside.

So please set bias current for Hall element to make amplitude of Hall input voltage over minimum input voltage

difference input terminals of Hall amplifier. The in-phase input voltage range designed for Hall input Amplifier is

become "H" or "L", detect circuit detects these Hall input abnormalities and makes all driver outputs "Hi-z".

9) FG Output Terminal (FGO)

1FG or 3FG signal that is reshaped by hall signal is output from FGO terminal. It is does not have output in stand-by

mode. In addition, because FG terminal is output from open drain, please use resistance of about 10k

Ω to 100kΩ

pulled up from outside. In that case, please be careful that FGO voltage or current never exceed rating.

10) Power Supply Terminal (VCC)

switching. Please add capacity of capacitor as necessary when using large current and motor with large BEMF.

Moreover, it is recommended to place laminated ceramic capacitor of around 0.01µF to 0.1µF in parallel on the

VCC terminal has clamp element for preventing ESD damage. If applying steep pulse signal and voltage such as

surge more than ratings, this clamp element operates, which might be a cause of destruction. It is effective to put

between VCC and GND terminals. Please note that IC might be destroyed when BEMF is applied to VCC and GND

terminals.

11) Ground Terminal (GND, PGND)

Wiring impedance from this terminal should be as low as possible for reducing noise of switching current and

stabilizing basic voltage inside of IC, and the impedance also should be the lowest potential in any operating

condition. In addition, please do pattern design not to have same impedance as other GND pattern.

12) Driver Output Terminal (U, V, W)

Impedance wiring should be thick, short, and low due to motor drive current. When using big current, in case that

driver current changes considerably toward positive and negative (when BEMF is large), malfunction or destruction of

IC might occur. It is effective to add shot key diode. Moreover, clamp element is built in driver output terminal in order

to prevent ESD damage. If applying steep pulse signal or voltage such as surge more than ratings, this clamp

element operates. Then it might cause destruction of IC, so that please pay attention not to exceed ratings.

Additionally, When driver output converts "L"→"H" or "H"→"L", for example when synchronous rectification PWM

operating , dead time (1µs to 2µs(Typ)) can be set to prevent simultaneous ON of output top & bottom MOS.

13) Capacitor Connection Terminal for Boosting, Boosting Output Terminal (CP1, CP2, VG)

VG terminal by connecting capacitor between CP1 to CP2 terminals and VG to VCC terminals. It is recommended to

use capacitor more than 0.1µF.
