Data Sheet
Status Flag
The two status flag outputs are an open drain output with Zener-diode which require a
pull-up resistor, c.f. the application circuit on page 15. ST1 and ST2 provide separate
diagnosis for each high-side switch. Various errors as listed in the table “Diagnosis” are
detected by switching the open drain output ST1/2 to low. Forward current in the
integrated body diode of the highside 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 lowside switches are off and R
BCR192W.
