4 / 12 page TC54 DS21434C-page 4 2002 Microchip Technology Inc. 3.0 DETAILED DESCRIPTION In normal steady-state operation, when VIN > VDET -, the output will be at a logic high, see Figure 3-1. In the case of the TC54V, this is an open-drain condition. If and when the input falls below VDET -, the output will pull down (Logic 0) to VSS. Generally, VOUT can pull down to within 0.5V of VSS at rated output current and input voltage. (See Section 1.0, Electrical Characteristics). The output, VOUT, will stay 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 will become valid. VOUT will be 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. (High for TC54VC, open-drain for TC54VN). FIGURE 3-1: TIMING DIAGRAM 4.0 APPLICATIONS INFORMATION Refer to Microchip Technology Application Note #779, Using the TC54 Voltage Detector.
