STP16CPC26
In order to correctly regulate the current, a minimum dropout voltage must be assured
across the current generators.
Figure 16: "Dropout voltage vs output current" and Table 9: "Dropout voltage vs output
current" provides just an indicative idea about the dropout voltage to assure over the
current range. However it is recommended to use value of VDROP slightly higher than those
indicated in Figure 16: "Dropout voltage vs output current" and Table 9: "Dropout voltage vs
output current".

10 Thermal shutdown
The STP16CPC26 is featured with a thermal shutdown. This protection is triggered if the
junction temperature reaches 170 °C. When the thermal shutdown is activated, all outputs
are turned off independently on the data latched. Once the temperature decreases (thermal
shutdown hysteresis is typically 15 °C), the outputs are enabled again and the device
keeps on working.
Once the temperature decreases (thermal shutdown hysteresis is typically 15°C), the
outputs are enabled again and the device keeps on working.
