Introduction

The TPS3305-18DRG4 Supervisors are a type of power management integrated circuit (PMIC) or an integrated circuit (IC). Specifically, they are part of the TPS3305 family of supervisors. The TPS3305-18DRG4 is able to regulate, supervise, and protect input voltage supplies. It is used to both ensure the smooth running and safeguard systems against damage or injury. The TPS3305 series, of which the TPS3305-18DRG4 is a member, are specifically designed small-dimension voltage supervisors. This article will examine the various application fields of the TPS3305-18DRG4 as well as its working principle.

Application Fields

The TPS3305-18DRG4 is used in many different applications. The first of these is portable systems. Smaller devices generally require lower input voltages and power consumption and hence the TPS3305-18DRG4, is the perfect fit for these situations. It has an input voltage range of 1.8V to 5.5V and extremely low power consumption of 0.18uA. The ‘green’ approach to its design (minimal power consumption) means it is perfect for battery operated devices meaning low battery drains in those emergency situations.In addition to this it is used in industrial applications such as medical equipment and steam generation. The TPS3305-18DRG4 ensures safety, reliability and efficiency in these situations.Finally, It is used in Automotive applications. The low power dissipation and small size of the TPS3305-18DRG4 is also beneficial here as it allows automotive applications to be miniaturised. This allows for reduced cost and saves valuable space. The low power mode of the TPS3305-18DRG4 also keeps the environmental impact low, thus making it the perfect choice for energy conscious engineers and designers.

Features of TPS3305-18DRG4

The TPS3305-18DRG4 has many features that set it apart from other PMICs. The first of these is that it is a 5-pin SOT23-2 package. This means that it is both small and easy to integrate. It also means that it can be easily soldered onto a board. It also has an internally set input voltage of 2.0V(±0.2V) and detects power supply reversals (Voltages above, or below the set voltage). This is beneficial as it increases the efficiency and reliability of the systems. The TPS3305-18DRG4 also features an input voltage hysteresis of 0.2V and an extremely low power consumption of 0.18uA. This allows it to be used in battery powered or energy saving applications as it will reduce the load on the batteries.Finally, the TPS3305-18DRG4 has an open circuit Response Time of 1ms maximum and a short circuit Response Time of 2ms maximum. This allows the TPS3305-18DRG4 to detect any instability or damage to the system quickly. This can result in a permanent shut-down of any systems, thus ensuring the safety of all users.

Working Principle

The working principle of the TPS3305-18DRG4 is fairly simple. It is designed to detect any power supply reversals (Voltages above, or below the set voltage) and output a high-level signal. This signal then triggers a shut-down of the system to protect it from any damage or injury. The TPS3305-18DRG4 features an internal voltage-detection circuit and a comparator. This voltage-detection circuit detects and sends the voltage signals to the comparator which then compares the signal to the reference voltage and outputs a logic-level signal. This signal will then be used by the system to trigger the shut-down.Thus, the TPS3305-18DRG4 is able to regulate, supervise and protect all input voltage supplies in order to ensure the smooth running and safety of the system.

Conclusion

In conclusion, the TPS3305-18DRG4 Supervisors are small-dimension voltage supervisors that can be used in many different applications. From portable devices to industrial, medical and automotive applications, the TPS3305-18DRG4 is the perfect choice for engineers and designers. This is thanks to its small size, low power consumption, and efficient detection and shut down system. The working principle of the TPS3305-18DRG4 is also very simple and is able to safeguard systems against any damage or injury brought by power supply reversals. Thus the TPS3305-18DRG4 is the ideal choice for power management integrated circuits and integrated circuits.
