Functional Description：
1、 When input voltage (VIN) rises above detect voltage (–VDET), output voltage (VOUT) will be equal to VIN. 2、 When input voltage (VIN) falls below detect voltage (–VDET), output voltage (VOUT) will be equal to the ground voltage (VSS) level. 3、 When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become unstable. In this condition, V IN will equal the pulled-up output (should output be pulled-up.) 4、 When input voltage (VIN) rises above the ground voltage (VSS) level, output will be unstable at levels below the minimum operating voltage (VMIN). Between the VMIN and detect release voltage (+VDET) levels, the ground voltage (VSS) level will be maintained. 5、 When input voltage (VIN) rises above detect release voltage (+VDET), output voltage (VOUT) will be equal to VIN. 6、 The difference between +VDET and –VDET represents the hysteresis range.
