Figure 1: TMC222 Typical Application
Notes :
• Resistors tolerance +- 5%
• 2.7nF capacitors: 2.7nF is the minimum value, 10nF is the maximum value
• the 1µF and 100µF must have a low ESR value
• 100nF capacitors must be close to pins V
BB
and V
DD
• 220nF capacitors must be as close as possible to pins CPN, CPP, V
CP
and V
BB
to reduce EMC radiation.
