The TLV6703-Q1 is a wide-supply voltage range (1.8 V to 18 V) comparator with a high-accuracy rising input threshold of 400 mV (1% over temperature) and built-in hysteresis. The output is also rated to 18 V, independant of supply voltage, and can sink up to 40 mA. The TLV6703-Q1 asserts the output signal, as shown in Table 8-1. To monitor any voltage above 0.4 V, set the input using an external resistor divider network. Each input pin has very low input leakage current, allowing the use of large resistor dividers without sacrificing system accuracy. Broad voltage thresholds are supported that enable the device for use in a wide array of applications. Table 8-1.

The comparator rising threshold is trimmed to be equal to the reference voltage (400 mV). The comparator also has a built-in falling hysteresis that makes the device less sensitive to supply-rail noise and provides stable operation. The comparator input (SENSE) is able to swing from ground to 6.5 V, regardless of the device supply voltage. Although not required in most cases, to reduce sensitivity to transients and layout parasitics for extremely noisy applications, place a 1-nF to 10-nF bypass capacitor at the comparator input. OUT is driven to logic low when the input SENSE voltage drops below (VIT-). When the voltage exceeds VIT+, the output (OUT) goes to a high-impedance state; see Figure 7-1 . 8.3.2 Output Pin (OUT) In a typical TLV6703-Q1 application, the output is connected to a GPIO input of the processor (such as a digital signal processor [DSP], central processing unit [CPU], field-programmable gate array [FPGA], or applicationspecific integrated circuit [ASIC]). The TLV6703-Q1 device provides an open-drain output (OUT). Use a pullup resistor to hold this line high when the output goes to high impedance (not asserted). To connect the output to another device at the correct interface-voltage level, connect a pullup resistor to the proper voltage rail. The TLV6703-Q1 output can be pulled up to 18 V, independent of the device supply voltage. Table 8-1 and the Section 8.3.1 section describe how the output is asserted or deasserted. See for a Figure 7-1 timing diagram that describes the relationship between threshold voltage and the respective output. 8.3.3 Immunity to Input-Pin Voltage Transients The TLV6703-Q1 is relatively immune to short voltage transient spikes on the sense pin. Sensitivity to transients depends on both transient duration and amplitude; see Figure 7-7, Minimum Pulse Width vs Threshold Overdrive Voltage. 8.4 Device Functional Modes 8.4.1 Normal Operation (VDD > UVLO) When the voltage on V DD is greater than 1.8 V for at least 150 µs, the OUT signal correspond to the voltage on SENSE as listed in Table 8-1. 8.4.2 Undervoltage Lockout (V(POR) < VDD < UVLO) When the voltage on V DD is less than the device UVLO voltage, and greater than the power-on reset voltage, V (POR), the OUT signal is asserted regardless of the voltage on SENSE. 8.4.3 Power-On Reset (VDD < V(POR)) When the voltage on V DD is lower than the required voltage to internally pull the asserted output to GND (V (POR)), SENSE is in a high-impedance state.

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. 9.1 Application Information The TLV6703-Q1 device is a wide-supply voltage comparator that operates over a VDD range of 1.8 V to 18 V. The device has a high-accuracy comparator with an internal 400-mV reference and an open-drain output rated to 18 V for precision voltage detection. The device can be used as a voltage monitor. The monitored voltage are set with the use of external resistors. 9.1.1 VPULLUP to a Voltage Other Than VDD The output is often tied to V DD through a resistor. However, some applications may require the output to be pulled up to a higher or lower voltage than V DD to correctly interface with the reset and enable pins of other devices.

The resistors can have high values to minimize current consumption as a result of low input bias current without adding significant error to the resistive divider.

This confirmation is calculated by verifying that the pullup voltage minus the output-leakage current (I lkg(OD)) multiplied by the resistor is greater than the desired logic-high voltage. These values are specified in the Section 7.5. Use Equation 2 to calculate the value of the pullup resistor. VPU (VHI - VPU) ³ RPU ³ IO Ilkg(OD) (3) 9.2.2.3 Input Supply Capacitor Although an input capacitor is not required for stability, for good analog design practice, connect a 0.1-μF low equivalent series resistance (ESR) capacitor across the VDD and GND pins. A higher-value capacitor may be necessary if large, fast rise-time load transients are anticipated, or if the device is not located close to the power source. 9.2.2.4 Sense Capacitor Although not required in most cases, for extremely noisy applications, place a 1-nF to 10-nF bypass capacitor from the comparator input (SENSE) to the GND pin for good analog design practice. This capacitor placement reduces device sensitivity to transients. 9.2.3 Application Curves Positive-Going Input Threshold (mV) 401 VDD = 1.8 V VDD = 5 V VDD = 12 V VDD = 18 V 400.6 400.2 399.8 399.4 399 -40 -25 -10 5 20 35 50 65 Temperature (qC) 80 95 110 125 Figure 9-5. Rising Input Threshold Voltage (VIT+) vs Temperature 9.3 Dos and Don'ts Do connect a 0.1-µF decoupling capacitor from VDD to GND for best system performance. If the monitored rail is noisy, do connect a decoupling capacitor from the comparator input (sense) to GND. Don't use resistors for the voltage divider that cause the current through them to be less than 100 times the input current of the comparator without also accounting for the effect to the accuracy. Don't use a pullup resistor that is too small, because the larger current sunk by the output then exceeds the desired low-level output voltage (VOL).

In the upper right corner, click on Alert me to register and receive a weekly digest of any product information that has changed. For change details, review the revision history included in any revised document. 12.3 Support Resources TI E2E™ support forums are an engineer's go-to source for fast, verified answers and design help — straight from the experts. Search existing answers or ask your own question to get the quick design help you need. Linked content is provided "AS IS" by the respective contributors. They do not constitute TI specifications and do not necessarily reflect TI's views; see TI's Terms of Use. 12.4 Trademarks TI E2E™ is a trademark of Texas Instruments. All trademarks are the property of their respective owners. 12.5 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 12.6 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 13 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
