WAVEFORMS AND TRUTH TABLE
TRUTH TABLE IN NORMAL OPERATING CONDITIONS
In normal operating conditions the DIAG
pulled high.
PWM pin usage:
In all cases, a “0” on the PWM pin will turn-off both LSA and LSB switches. When PWM rises back to “1”, LS
turn on again depending on the input pin state.
NB: in no cases external pins (except for GND
