● Safety measure
1) Reverse connection protection diode
Reverse connection of power results in IC destruction as shown in Fig 16. When reverse connection is possible,
reverse connection protection diode must be added between power supply and Vcc.

2) About measures of voltage rise by back electromotive force
The voltage of output terminal rises by back electromotive force. The diode D1 of Fig.17 is necessary to divide a power
supply line of motor with small signal line, so that the voltage of the output does not affect a power supply line.

Fig.18 Protection of FG and AL terminal
FG and AL output is an open collector and requires pull-up resistor.
The IC can be protected by adding resistor R1. An excess of absolute maximum rating, when FG or AL output terminal
is directly connected to power supply, could damage the IC.
