Reset Timing Thermal Shutdown minus Thermal Hysteresis Reset Delay Time Reset Delay Time t < Reset Reaction Time During power−up (or restoring OUT voltage from a reset event), the OUT voltage must be maintained above the Reset threshold for the Reset Delay time before RO goes high. The time for Reset Delay is determined by the choice of IC and the state of the DT pin. Reset Delay Time Select Selection of the NCV8660B device and the state of the DT pin determines the available Reset Delay times. The part is designed for use with DT tied to ground or OUT, but may be controlled by any logic signal which provides a threshold between 0.8 V and 2 V. The default condition for an open DT pin is the slower Reset time (DT = GND condition). Times are in pairs and are highlighted in the chart below. Consult factory for availability. DT=GND DT=OUT Reset Time Reset Time NCV86601B 8 ms 128 ms NCV86602B 8 ms 32 ms NCV86603B 16 ms 64 ms NCV86604B 32 ms 128 ms The Delay Time select (DT) pin is logic level controlled and provides Reset Delay time per the chart. Note the DT pin is sampled only when RO is low, and changes to the DT pin when RO is high will not effect the reset delay time. Thermal Shutdown When the die temperature exceeds the Thermal Shutdown threshold, a Thermal Shutdown event is detected OUT is turned off, and RO goes low. The IC will remain in this state until the die temperature moves below the shutdown threshold (175 °C typical) minus the hysteresis factor (25°C typical). The output will then turn back on and RO will go high after the RESET Delay time. |
