5 Common Settings

The peak current limit setting (IPK) and deadtime setting (DT/SD) are shared between the two channels.

When different peak current is required by CH1 and CH2, adjust the current sense resistor to get different peak current limit for each channel.

Both channels shut down and latch when DT/SD is pulled low.
