8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLV703x and TLV704x are nano-power comparators with reasonable response time. The comparators have
a rail-to-rail input stage that can monitor signals beyond the positive supply rail with integrated hysteresis. When
higher levels of hysteresis are required, positive feedback can be externally added. The push-pull output stage of
the TLV703x is optimal for reduced power budget applications and features no shoot-through current. When level
shifting or wire-ORing of the comparator outputs is needed, the TLV704x with its open-drain output stage is well
suited to meet the system needs. In either case, the wide operating voltage range, low quiescent current, and
small size of the TLV703x and TLV704x make these comparators excellent candidates for battery-operated and
portable, handheld designs.
8.1.1 Inverting Comparator With Hysteresis for TLV703x
The inverting comparator with hysteresis requires a three-resistor network that is referenced to the comparator
supply voltage (VCC), as shown in Figure 34. When VIN at the inverting input is less than VA, the output voltage is
high (for simplicity, assume VO switches as high as VCC). The three network resistors can be represented as R1
|| R3 in series with R2. Equation 1 defines the high-to-low trip voltage (VA1).
(1)
When VIN is greater than VA, the output voltage is low, very close to ground. In this case, the three network
resistors can be presented as R2 || R3 in series with R1. Use Equation 2 to define the low to high trip voltage
(VA2).
(2)
Equation 3 defines the total hysteresis provided by the network.
