4 / 14 page  TC51 DS21429B-page 4 2002 Microchip Technology Inc. 3.0 DETAILED DESCRIPTION In normal steady-state operation, when VIN > VDET -, the output is high, see Figure 3-1. If and when the input falls below VDET -, the output pulls down (Logic 0) to VSS. Generally, VOUT can pull down to within 0.5V of VSS at rated output current and input voltage. (Also see Section 1.0, Electrical Characteristics). The output, VOUT, stays valid until the input voltage falls below the minimum operating voltage, VINMIN, of 0.7V. Below this minimum operating voltage, the output is undefined. During power-up or anytime VIN has fallen below VINMIN, VOUT will remain undefined until VIN rises above VINMIN, at which time the output becomes valid. VOUT is maintained in its active low state while VINMIN <VIN < VDET+. (VDET+ = VDET - + VHYST). If and when the input rises above VDET+, the output will assume its inactive state after Delay Time (TDLY).
