2.4 Waveforms and truth table
In normal operating conditions the DIAG
X
/EN
X
pin is considered as an input pin by the
device. This pin must be externally pulled-high
PWM pin usage: in all cases, a “0” on the PWM pin turns-off both LS
A
and LS
B
switches.
When PWM rises back to “1”, LS
A
or LS
B
turn-on again depending on the input pin state.
