2-4) S3 command (The manual output open/short detection functions are executed.)

Operation) In the number of SCK pulses at TRANS="H" is 9 or 10, the following operation is executed.

The manual output open/short detection functions are executed. Note1

The output is compulsorily turned on during tON(S3) with about 60μA. And detection is done.

The manual output open/short detection result data is transmitted to the 16-bit shift register.

tON(S3) is about 800ns.

For the period of tON(S3), please set SCK and TRANS to “L”.

When inputting this command during PWM output, the manual output open/short detection

functions are executed after the PWM output. In this case, tON(S3) occurs after a PWM output.

Basic input pattern of S3 command)

The first SCK (signal X) after this command is used for transmission of the output open/short

detection result data. The input from SIN is not received. Note1

Note1: This operation is performed when the output open/short detection function is “Active” setting.

The output open/short detection functions are set by S6 command.

Default setting is “Not Active”.

2-5) S4 command (Reset of the internal PWM counter.)

Operation) In the number of SCK pulses at TRANS="H" is 11 or 12, the following operation is executed.

The internal PWM counter is reset.

When the internal PWM counter is reset, the output is turned off.

It is necessary to input S1 command to turn on the output again.
