Protection and Diagnostics

In case the measured voltage at pin OCP is higher than the internal threshold VOCPD1, an Emergency (Safe) Turn-

off sequence is initiated, bit SER.OCPER is set and a fault notification is issued on pin NFLTA (in case of an OPM

transition the state machine - see Chapter 2.4.7). In case the measured voltage at pin OCP is higher than the

internal threshold VOCPD2, the sticky bit SSTAT.OCPCD is set. The allows to verify during application run time the

signal integrity of the sense path. The OCP function is not active while the output stage is in PWM OFF state.

Note: Both DESAT and OCP protection mechanisms can be used simultaneously.

Note: In case the OCP pin is open, the pull-up resistance ensures that an OCP event is generated.
