ZHCSED3A –NOVEMBER 2015–REVISED SEPTEMBER 2018
7 Detailed Description
7.1 Overview
The TPS3711 combines a comparator and a precision reference for undervoltage detection. The TPS3711
features a wide supply voltage range (1.8 V to 36 V) and a high-accuracy threshold voltage of 400 mV (0.75%
over temperature) with built-in hysteresis. The output is rated to 25 V and can sink up to 10 mA.
Set the input pin (SENSE) to monitor any voltage above 0.4 V by using an external resistor divider network.
SENSE has very low input leakage current, allowing the use of a large resistor divider without sacrificing system
accuracy. The relationship between the input and the output is shown in 表 1. Broad voltage thresholds are
supported that enable the device to be used in a wide array of applications.

7.3 Feature Description
7.3.1 Input Pin (SENSE)
The TPS3711 combines a comparator with a precision reference voltage. The comparator has one external input
and one internal input connected to the internal reference. The falling threshold on SENSE is designed and
trimmed to be equal to the reference voltage (400 mV). This configuration optimizes the device accuracy. The
comparator also has built-in hysteresis that proves immunity to noise and ensures stable operation.
The comparator input swings from ground to 6.5 V (7.0 V absolute maximum), regardless of the device supply
voltage used. Although not required in most cases, it is good analog design practice to place a 1-nF to 10-nF
bypass capacitor at the comparator input for noisy applications in order to reduce sensitivity to transient voltage
changes on the monitored signal.
For the comparator, the output (OUT) is driven to logic low when the input SENSE voltage drops below VIT–
.
When the voltage exceeds VIT+, OUT goes to a high-impedance state; see 图 1.
7.3.2 Output Pin (OUT)
In a typical TPS3711 application, the output is connected to a reset or enable input of the processor [such as a
digital signal processor (DSP), application-specific integrated circuit (ASIC), or other processor type] 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 TPS3711 provides an open-drain output (OUT); use a pullup resistor to hold the line high when the output
goes to a high-impedance state. Connect this pullup resistor to a voltage rail that meets the logic requirements of
the downstream device. The TPS3711 output can be pulled up to 25 V, independent of the device supply
voltage. To ensure the proper voltage level, give some consideration when choosing the pullup resistor value.
The pullup resistor value is determined by VOL, output capacitive loading, and the open-drain leakage current
(ID(leak)). These values are specified in the Electrical Characteristics table.
表 1 and the Input Pin (SENSE) section describe how the output is asserted or high impedance. See 图 1 for a
timing diagram that describes the relationship between threshold voltage and the respective output.
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 155 µs, the OUT signal corresponds to the voltage on
SENSE, as listed in 表 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)), OUT is in a high-impedance state.

8 Application and Implementation
注
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 TPS3711 is used as a precision voltage supervisor in several different configurations. The monitored voltage
(VMON), VDD voltage, and output pullup voltage can be independent voltages or connected in any configuration.
The following sections show the connection configurations and the voltage limitations for each configuration.

(1)
Choose an RTOTAL ( = R1 + R2) so that the current through the divider is approximately 100 times higher than the
input current at the SENSE pin. Use resistors with 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 logic-high voltage level (VHI), select a pullup resistor value where the pullup voltage divided
by the pullup resistor value does not exceed the sink-current capability of the device. Confirm this voltage level
by verifying that the pullup voltage minus the open-drain leakage current (ID(leak) ) multiplied by the resistor is
greater than the desired VHI. These values are specified in the Electrical Characteristics .
Use 公式 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.

9 Power Supply Recommendations
The TPS3711 has a 40-V absolute maximum rating on the VDD pin, with a recommended maximum operating
condition of 36 V. If the voltage supply that provides power to VDD is susceptible to any large voltage transient
that may exceed 40 V, or if the supply exhibits high voltage slew rates greater than 1 V/µs, then place an RC
filter between the supply and VDD to filter any high-frequency transient surges on the VDD pin. In these cases, a
100-Ω resistor and 0.01-µF capacitor are required, as shown in 图 17.

10 Layout
10.1 Layout Guidelines
•
•
•
Place R1 and R2 close to the device to minimize noise coupling into the SENSE node.
Place the VDD decoupling capacitor close to the device.
Avoid using long traces for the VDD supply node. The VDD capacitor (CVDD), along with parasitic inductance
from the supply to the capacitor, might form an LC tank and create ringing with peak voltages above the
maximum VDD voltage. If long traces are unavoidable, see 图 17 for an example of filtering VDD.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
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.
