Recommended Power-on Sequence
Notes on Board Design Layout
Provide a wait time of 10µs or more after the V CC power supply rises before supplying the motor power supply.
Provide a wait time of 10µs or more after the motor power supply rises before setting the ST pin High.
The above power-on sequence is only a recommendation, and there is no risk of damage to the IC even if this
sequence is not followed.
• Use thick GND lines and connect to GND stabilization points by the shortest distance possible to lower the
• Use thick VM, VM1 and VM2 lines, and short-circuit these lines to each other by a short distance.
• Place the capacitors connected to V CC and VM as close to the IC as possible, and connect each capacitor to a
• Place the RF resistor as near to the IC as possible, and connect it to the GND stabilization point using a thick
