The maximum operating P-DSO-20-6 voltage is 45 V. The output is able to drive a 150 m A load. It is short circuit protected and the thermal shutdown switches the output off if the junction temperature is in excess of 150 °C. A reset signal is generated for an output voltage of VQ < 4.6 V. The reset threshold voltage can be decreased by external connection of a voltage divider. The reset delay time can be set by an external capacitor. If the application requires pull up resistors at the logic outputs (Reset, P-DSO-14-4 Sense Out) the TLE 4269 with integrated resistors can be used. It is also possible to supervise the input voltage by using an integrated parator to give a low voltage warning.
