PBTL mode. Only PWM_A input is used.
Protection works similarly to BTL mode

. Only
difference in SE mode is that OUT_X is Hi-Z
instead of a pulldown through internal pulldown
resistor.

The 1N and 2N naming convention is used to indicate the required number of PWM lines to the power stage per channel in a specific
mode.
An overload protection (OLP) occurring on A or B causes both channels to shut down. An OLP on C or D works similarly. Global errors
like overtemperature error (OTE), undervoltage protection (UVP), and power-on reset (POR) affect all channels.
