The TPS3110K33DBVRG4 is a very popular power management integrated circuit, or PMIC, designed particularly for embedded and system applications. It is part of the larger TPS3110K33 family of devices, which also includes other devices with functions such as LED drivers and multiplexers. The TPS3110K33DBVRG4 is classified as a supervisor PMIC, and due to its unique features and benefits, it is becoming increasingly popular for many applications.

Features

The TPS3110K33DBVRG4 provides several features and capabilities that make it an ideal choice for many embedded and system applications. These features include:

• Low quiescent current (1.5 μA typical, 10 μA Max)
• 3.3V reset input thresholds
• Adjustable reset input thresholds
• Two-cycled reset output pulse

These features allow for precise control and power management of the device, enabling it to be used in a variety of designs, from high-speed clock systems to ultra-low power applications.

Applications

The TPS3110K33DBVRG4 is primarily designed to provide system reset and power monitoring functions in modern embedded and system applications. Specifically, it can be used in the following applications:

• Clocks systems
• Thermal management
• Low power devices
• Power sequencing and sequencing
• High speed voltage/current conversion
• Memory protection
• Radiofrequency (RF) transceiver

Due to its ability to precisely control reset thresholds and its low power consumption, the TPS3110K33DBVRG4 is ideal for use in a wide range of embedded and systems applications.

Working Principle

The TPS3110K33DBVRG4 works by monitoring the power supply voltage and providing a reset output if the voltage falls below a predetermined level. The device offers an adjustable reset threshold voltage, allowing for precise control over the reset output. The operating voltage range of the TPS3110K33DBVRG4 is 1.6V to 3.6V, and the quiescent current (IDD) is 1.5 μA typical, 10 μA max.

When the supply voltage (Vcc) is above VddUV, the reset output (RST) is a low level. If the supply voltage drops below the correct reset threshold (VDDCMP), the reset output will be switched to a high level. This high level will remain until the supply voltage again rises above the correct reset threshold. The TPS3110K33DBVRG4 also offers a low-power mode which reduces current consumption to just 0.10 μA.

As the reset output is triggered, the device will also provide a two-cycle reset output pulse. This pulse can then be used to reset any associated system components, and provide the necessary low-power and system reset functions.

Conclusion

The TPS3110K33DBVRG4 is a popular power management integrated circuit, designed particularly for embedded and system applications. It is classified as a supervisor PMIC and is becoming increasingly popular due to its unique features and benefits, such as its low quiescent current draw and adjustable reset thresholds. Its applications are diverse, from high-speed clock systems to radiofrequency (RF) transceivers, and it provides a precise reset output with a two-cycle reset pulse.
