TPS3808G33QDBVRQ1 Description

When the sense voltage drops below a level or the manual reset (MR) pin goes logic low, the TPS3808Gxx-Q1 microprocessor’s supervisory circuitry sends an open-drain RESET signal. The user can set the limits for these events. When the sense voltage and MR go back over their limits, the reset output stays low for a time that the user can set. At VIT 3.3 V, the TPS3808Gxx-Q1 device can reach a threshold accuracy of 0.5% when used with a precision reference.

When the CT pin is disconnected, the reset delay lasts 20 ms; when it is connected to VDD through a resistor, it lasts 300 ms; and when it is connected to an external capacitor, it can last anywhere from 1.25 ms to 10 s. The TPS3808Gxx-Q1 is perfect for use in portable, battery-powered devices because its normal quiescent current is about 2.4 A. The device is fully defined from -40 degrees Celsius to +125 degrees Celsius (TJ) and comes in a small SOT-23 box (one choice in WSON).

TPS3808G33QDBVRQ1 Feature Description

● SENSE Input

The SENSE input has a terminal where any voltage in the device can be checked. If the voltage on this pin goes below VIT, RESET is said to be low. The comparison has hysteresis built in to make sure that reset assertions and deassertions happen smoothly. Putting a 1- to 10-nF bypass capacitor on the SENSE input is a good way to make the circuit less sensitive to sudden changes and layout parasitics.

● Manual Reset (MR) Input

With the manual reset (MR) input, a restart can be started by a processor or other logic circuits. When MR is logic low (0.3 VDD), RESET goes low. After the user-defined reset delay has passed and MR has gone back to a logic high and SENSE is above its reset level, the high state of RESET is cleared. A 90-k resistor is used to connect MR to VDD on the inside, so this pin can be left disconnected if MR is not being used.

● Immunity to SENSE Pin Voltage Transients

With the TPS3808Gxx-Q1, you will have the best defence against voltage spikes. It is more resistant to small negative spikes on the SENSE pin because of how well it is made. You can rest easy knowing that your system is stable and effective, even when things get tough. You can count on the TPS3808Gxx-Q1 to work well and not stop.

Application Information

When either the manual reset (MR) is pushed low or the sense pin voltage falls below VIT, the TPS3808G33QDBVRQ1 microprocessor supervisory product family is designed to deliver a reset signal. After both the manual reset (MR) voltage and the sense voltage return above their respective limits, the reset output stays on for a time that can be set by the user. There are many different voltage cutoffs and reset delay time settings, so these devices can be used in many different ways. Reset threshold voltages can be set in the factory to be between 0.82 V and 3.3 V or between 4.4 V and 5 V. With an external resistor divider, the TPS3808G01-Q1 can be set to any voltage above 0.405 V.

The user can also choose between two pre-set delay times. If the CT pin is connected to VDD, the reset delay is 300 ms. If the CT pin is left open, the reset delay is 20 ms. Also, the creator can choose any reset delay time between 1.25 ms and 10 s by connecting a capacitor between CT and GND.

Device Functional Modes

The TPS3808Gxx-Q1 gives you exact control over the reset. Its smart functional modes react to different situations. For example, when the MR pin is high and the sense input is higher than VIT, the reset pin is no longer held high, making the system stable. If MR is low or SENSE goes below VIT, RESET is asserted low, which starts a controlled reset. You can depend on the TPS3808Gxx-Q1 to work smoothly and reliably in your computer systems.

Power Supply Recommendations

The TPS3808Gxx-Q1 devices, which are known for their reliability and performance, need a certain type of power source to work well. These gadgets are made to work with a wide range of power supplies, from 1.8 V to 6.5 V. Texas Instruments (TI) suggests putting a 0.1-F capacitor close to the VDD pin to improve its function. By following these power source rules, you can make sure that your TPS3808Gxx-Q1 devices work as well and efficiently as possible.

Layout

● Layout Guidelines

Texas Instruments (TI) gives specific layout suggestions for where to put components in relation to the TPS3808Gxx-Q1 devices so that your design works as well as possible. One important tip is to put a buffering capacitor with a value of 0.1 F close to the VDD pin. This capacitor helps to cut down on noise and keep the device’s power supply stable.

Also, it is very important to make sure that the VDD trace can carry a current of up to 6 A without the voltage dropping a lot. This helps to make sure that the TPS3808Gxx-Q1 devices have a stable power supply, which improves their general performance and reliability.

By following these planning rules, you can make sure the TPS3808Gxx-Q1 devices work reliably and improve the functionality and efficiency of your design.

Conclusion

In conclusion, the speed and dependability of the TPS3808Gxx-Q1 devices from Texas Instruments are unmatched in the world of electronic systems. With an input supply range of 1.8 V to 6.5 V and excellent voltage tracking capabilities, these components raise the bar for excellence.
