FIGURE 8. TRIP TEST Digital Output Test Circuit

The TRIP TEST pin, normally used to check the operation of the OVERTEMP and OVERTEMP pins, may be used to latch the
outputs whenever the temperature exceeds the programmed limit and causes the digital outputs to assert. As shown in the figure,
when OVERTEMP goes high the TRIP TEST input is also pulled high and causes OVERTEMP output to latch high and the
OVERTEMP output to latch low. The latch can be released by either momentarily pulling the TRIP TEST pin low (GND), or by
toggling the power supply to the device. The resistor limits the current out of the OVERTEMP output pin.
