10 / 23 page STK672-740B-E No. A1932-10/23 [Configuration of Each Input Pin] <Configuration of the φA, φAB, φB, φBB, <Configuration of the FAULT2 pin> ENABLE, and RESETB input pins> (The buffer has an open drain configuration.) All input pins of this driver support schmitt input. Typ 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 Vref input pin> <Configuration of the FAULT1 output pin> <FAULT1, FAULT2 output> FAULT1 Output FAULT1 is an open drain output. It outputs low level when any of motor terminal open, overcurrent, or overheat is detected. FAULT2 output Output is resistance divided (3 levels) and the type of abnormality detected is converted to the corresponding output voltage. • Motor terminal open: 10mV (typ) • Overcurrent: 2.5V (typ) • Overheat: 3.3V (typ) Abnormality detection can be released by a RESETB operation or turning VDD voltage on/off. VIHa When rising When falling 1.5V typ VILa 1.8V typ Input voltage Input pin 5V VSS 10k Ω 100k Ω 5V Overcurrent Overheating 50k Ω 50k Ω Output pin Pin 8 50k Ω Motor terminal open Vref/4.9 VSS Amplifier − + Input pin Pin 19 Output pin Pin 16 5V VSS Overcurrent Motor terminal open Overheating |
