No. A1136-10/19

[Configuration of I/O pins]

<Configuration of the

φA, φAB, φB, φBB, ENABLE, and RESETB input pins>

Input pins13, 17, 12, 10, 15, and 14

The input pins of this driver all use Schmitt input. Typical specifications at Tc=25

°C are given below. Hysteresis

voltage is 0.3V (VIHa-VILa).

Input voltage specifications are as follows.

VIH=2.5V min

VIL=0.8V max

<Configuration of the FAULT input pin>

<Configuration of the Vref input pin>

The internal impedance, 100k

Ω, is designed so that the increase in current is prevented while Pin 19 is open.

The recommended Vref voltage is 0.14V or higher because the output offset voltage of Vref/4.9 amplifier cannot be

controlled down to 0V
