AMIS-30622 I²C Microstepping Motordriver
7.0 Typical Application
Data Sheet
Notes
(1) Optionally an external switch to Vbat or GND can be
connected to the SWI pin.
(2) Resistors tolerance: ± 5%.
(3) Depending on the application the ESR value of the 1µF
and 100µF capacitors must be carefully chosen. The
working voltage of the 100µF capacitor depends on the
maximum Vbat value.
(4) 100nF capacitors must be close to pins VBB and VDD.
(5) 220nF capacitors must be as close as possible to pins
CPN, CPP, VCP, and VBB to reduce EMC radiation.
(6) If SDA and/or SCK input voltage ≤ 0.3V, then a resistor
of 22 to 100Ω must be added in series.
