TPS3710

ZHCSE85 –OCTOBER 2015
7 Detailed Description
7.1 Overview
The TPS3710 provides precision voltage detection. The TPS3710 is a wide-supply voltage range (1.8 V to 18 V)
device 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, and can sink up to 40 mA.
The TPS3710 asserts the output signal, as shown in Table 1. To monitor any voltage above 0.4 V, set the input
using an external resistor divider network. Broad voltage thresholds are supported that enable the device for use
in a wide array of applications.

TPS3710
ZHCSE85 –OCTOBER 2015

7.3 Feature Description
7.3.1 Input (SENSE)
The TPS3710 comparator has two inputs: one external input, and one input connected to the internal reference.
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, in order 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 1.
7.3.2 Output (OUT)
In a typical TPS3710 application, the output is connected to a reset or enable input of the processor (such as a
digital signal processor [DSP], central processing unit [CPU], field-programmable gate array [FPGA], or
application-specific integrated circuit [ASIC]) or the output is connected to the enable input of a voltage regulator
(such as a dc-dc converter or low-dropout regulator [LDO]).
The TPS3710 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 TPS3710 output can be pulled up to 18 V,
independent of the device supply voltage.
Table 1 and the Input (SENSE) section describe how the output is asserted or deasserted. See Figure 1 for a
timing diagram that describes the relationship between threshold voltage and the respective output.
7.3.3 Immunity to Input-Pin Voltage Transients
The TPS3710 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, Minimum Pulse Width vs Threshold Overdrive
Voltage.
7.4 Device Functional Modes
7.4.1 Normal Operation (VDD > UVLO)
When the voltage on VDD is greater than 1.8 V for at least 150 µs, the OUT signal correspond to the voltage on
SENSE as listed in Table 1.
7.4.2 Undervoltage Lockout (V(POR) < VDD < UVLO)
When the voltage on VDD 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.
7.4.3 Power-On Reset (VDD < V(POR)
)
When the voltage on VDD is lower than the required voltage to internally pull the asserted output to GND (V(POR)),
SENSE is in a high-impedance state.

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 TPS3710 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.
8.1.1 VPULLUP to a Voltage Other Than VDD
The output is often tied to VDD through a resistor. However, some applications may require the output to be
pulled up to a higher or lower voltage than VDD to correctly interface with the reset and enable pins of other
devices.

8.2 Typical Application
The TPS3710 device is a wide-supply voltage comparator that operates over a VDD range of 1.8 to 18 V. The
monitored voltage is set with the use of external resistors, so the device can be used either as a precision
voltage monitor.

R1 and R2 are the resistor values for the resistor divider on the SENSEx pins
VMON(UV) is the target voltage at which an undervoltage condition is detected
Choose RTOTAL ( = R1 + R2) so that the current through the divider is approximately 100 times higher than the
input current at the SENSE pin. 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. For details on sizing input
resistors, refer to application report SLVA450, Optimizing Resistor Dividers at a Comparator Input, available for
download from www.ti.com.

8.2.2.2 Pullup Resistor Selection
To ensure the proper voltage level, the pullup resistor value is selected by ensuring that the pullup voltage
divided by the resistor does not exceed the sink-current capability of the device. This confirmation is calculated
by verifying that the pullup voltage minus the output-leakage current (Ilkg(OD)) multiplied by the resistor is greater
than the desired logic-high voltage. These values are specified in the Electrical Characteristics .
Use Equation 2 to calculate the value of the pullup resistor.

8.2.2.3 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.
8.2.2.4 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.

8.3 Do's 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).

11.5 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.
