8 Detailed Description
8.1 Overview
The TPS380x-Q1 devices are low-current supervisory circuits used to monitor system voltages above 1.226 V.
The devices assert an active low RESET signal when VDD ,SENSE, or both voltages drop below a preset
threshold. The RESET output remains low until the VDD, SENSE, or both voltages return above their thresholds.
The devices are also designed to be immune to short negative transients on the VDD and SENSE pins.
8.2 Functional Block Diagrams
8.3 Feature Description
8.3.1 VDD and SENSE Monitoring
The VDD and SENSE inputs provide a pin at which a system voltage can be monitored. If the voltage on this pin
drops below VIT, RESET is asserted low. The comparator has a built-in hysteresis to ensure smooth RESET
assertions and de-assertions. Refer to the Device Comparison Table to determine the VDD and SENSE voltage
thresholds for each device. The adjustable version TPS3803-01-Q1 can be used to monitor any voltage rail down
to 1.226 V using the circuit shown in Figure 13, where VIT' is the Vin threshold voltage.

8.3.2 Transient Immunity
The TPS380x-Q1 devices are immune to short negative transients on the VDD and SENSE pins. Sensitivity to
transients is dependent on threshold overdrive as shown in Figure 15 and Figure 16. These graphs show the
duration that the transient is below VIT compared to the magnitude of the voltage drop below VIT, called the
threshold overdrive voltage. Any combination of transient duration and overdrive voltage which lies above the
curves will result in RESET being asserted low. Any transient which lies below the curves will be ignored by the
device.

8.4 Device Functional Modes
TPS3803-01-Q1 and TPS3803G15-Q1 monitor only one supply, which is SENSE and VDD respectively. When
that supply is above the VIT threshold, RESET will be high. Otherwise, RESET will be low. TPS3805H33-Q1
monitors both VDD and SENSE. When both VDD and SENSE are above the VIT threshold, RESET will be high.
Otherwise, RESET will be low.

9 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.
9.1 Application Information
The TPS380x-Q1 voltage supervisor devices are designed to assert an active-low RESET signal when VDD
and/or SENSE drop below a voltage threshold VIT. The RESET signal remains low until the voltages return
above their respective thresholds. The TPS3803G15-Q1 and TPS3805H33-Q1 are fixed-voltage options, while
the TPS3803-01-Q1 is adjustable and can be used to monitor any voltage above 1.226 V. The TPS3803G15-Q1
and TPS3803-01-Q1 have an open-drain output, requiring an external pull-up on the RESET line.
9.2 Typical Applications
9.2.1 TPS3803G15-Q1
Figure 17. TPS3803G15 Typical Application
9.2.1.1 Design Requirements
When a single 1.5-V supply rail needs to be monitored, TPS3803G15-Q1 should be used. When a single voltage
higher than 1.226 V needs to be monitored, TPS3803-01-Q1 should be used. When a 3.3-V supply and second
supply above 1.226 V needs to be monitored, TPS3805H33-Q1 should be used.
9.2.1.2 Detailed Design Procedure
To monitor a single 1.5-V supply with TPS3803G15-Q1, connect the 1.5-V supply directly to VDD. The RESET
output should be connected to the reset of the microcontroller with a pull-up resistor from the RESET output to
VDD.
To monitor a single supply using TPS3803-01-Q1, connect the supply to VDD with a resistor divider to scale down
the voltage at the SENSE pin. The resistor values must be chosen to satisfy Equation 1:
VIT' = (1 + R1/R2) × 1.226
where
• VIT’ is the VDD threshold voltage. (1)
For example, if TPS3803-01-Q1 should monitor a 2.5-V supply and the desired threshold voltage is 2.2 V, R1
and R2 values could be 24 kΩand 30- kΩrespectively. A 1-nf to 10-nF decoupling capacitor is recommended to
be placed close to the SENSE input.

Typical Applications (continued)
To monitor two supplies using TPS3805H33-Q1, connect the 3.3-V supply directly to VDD, and the second supply
through a resistor divider to the SENSE pin. The SENSE pin should have a 1-nf to 10-nF decoupling capacitor
close to the pin.

10 Power Supply Recommendations
The TPS380x-Q1 devices are designed to operate from an input supply from 1.3 V to 6 V. TI recommends to
place a 0.1-µF capacitor near the VDD pin.

11.1 Layout Guidelines
TI recommends to place the 0.1-µF decoupling capacitor close to the VDD pin. The VDD trace should be able to
carry 6 µA without a significant drop in voltage. Avoid a long trace from the SENSE pin to the resistor divider.
