10 +5 V REF
• This is an internally regulated and monitored reference voltage supply for external devices.
• This reference output can be switched on/off by application.
10.1 Protection features
• Overcurrent
• External voltage protection
• Errors are indicated with a fault signal
10.2 Voltage monitoring
The level of the output voltage can be monitored by application.

Note 1: When output voltage is under overload conditions, for example, short circuit to supply
voltages. Exceeding the max value might cause damage to output.
Note 2: Current limit for overcurrent protection to limit internal power dissipation.
Note 3: When the limit is exceeded, the output current is regulated. In regulation, the output is
switched into overcurrent mode.
Note 4: The measurement is scaled down before the conversion. The effect is compensated in
Epec software libraries. For more information, see Epec Programming and Libraries manual.
