Open Load Detection
Open load is detected by voltage measurement in Off state. If the output voltage exceeds
a specified level the error flag is set with a delay.
Status Flag
The status flag output is an open drain output with Zener-diode which requires a pull-up
resistor, c.f. the application circuit on page 14. Various errors as listed in the table
“Diagnosis” are detected by switching the open drain output ST to low. An open load
detection is available when there is an external resistor < R
0
from SH1 and SH2 pin to
DHVS or Vs. In order to reach low quiescent current, we recommend to disconnect this
resistor when not used.
