The device is optimized for low voltage operation from 2.7V to 5.5V single supply. It supports rail-to-rail input and output operation. With 4mA output current, the output voltage swing is within 190mV of the rails without external pull-up or pull-down circuitry. The SGM8746 is suitable for portable equipment. It can be compatible with CMOS and TTL logics. There are a lot of comparators switched frequently for the linear region as the effect of noise and parasitic parameters, and the condition of this negative situation is when the one input of the comparator tends to reach the other input voltage. In order to ease the effect of noise and parasitic parameter, there is a 2.5mV internal hysteresis inside the comparator. There are two trip points which are made by the comparator: the trip points when rising edge occurs and the trip points when falling edge occurs. And the gap between two trip points is the hysteresis of the comparator. The offset voltage VOS is defined as the average value of the two trip points. For the condition which two inputs of the comparator are nearly equal, the internal hysteresis will launch to avoid the frequently switching at this case. For the normal comparator other than SGM8746, the users usually use external resistors connected at +IN pin to provide hysteresis, while the internal hysteresis of SGM8746 can provide internal hysteresis without any external component. However, if users need more hysteresis to reject the influence of noise or parasitic parameters, please add the external resistors at +IN pin to increase the hysteresis. VTRIP+ VIN+ VHYST VTRIP+ + VTRIPVOS = 2 VIN- = 0 On the condition shown in Figure 1, the -IN is fixed while +IN is varied, and the corresponding output is shown under the figure of input signal. However, if +IN is fixed while -IN is varied, the output will be inverted. Output Structure In Figure 2, the SGM8746 has a push-pull output stage. When output is changed from logic high/low to low/high, the changed sink/source current pulls/pushes output pin to logic low/high. Beginning this transition, larger sink/source current is used to create a high slew rate transit from high/low to low/high. Once the output voltage reaches VOL/VOH, it will reduce the sink/source current to a just right value to maintain the VOL/VOH static condition. This current-driven push-pull output stage will significantly reduce the power consumption in application system. If low slew rate transition is needed in system design, adjusting the load capacitance will change the slew rate. The heavier capacitive load will slow down the output voltage transition. This feature will be used to reduce the interference generated by fast edge of transition between 1 and 0 in noise-sensitive system. +VS ISOURCE Output -VS ISINK Figure 2.
