3 / 12 page 2001-2015 Microchip Technology Inc. DS20001430E-page 3 TC52 2.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 2-1. 3.0 DETAILED DESCRIPTION In normal steady-state operation and for either channel, when VIN >VDET-, the output is high, see Figure 3-1. (In the case of the TC52N, this is an open- drain condition.) 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 voltages. (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 (open-drain for TC52N).
