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.
