MINA(B,C,D)1 is the low-side driver pin used with the minor gauges. The
current flow through the coil is restricted to one direction. Refer to

Refer to
To provide effective decoupling and to reduce radiated RF (radio
frequency) emissions, small decoupling capacitors must be located as
close to the supply pins as possible. The self-inductance of these
capacitors and the parasitic inductance and capacitance of the
interconnecting traces determine the self-resonant frequency of the
