Data Sheet
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. Forward current
in the integrated body diode of the high-side switch may cause undefined voltage levels
at the corresponding status output. The open load detection can be used to detect a
short to Vs as long as both low-side switches are off and R
by BCR192W.
