A PMIC-Supervisors, TPS3613-01DGSR, is the most advanced component of the power management integrated circuit (PMIC)-supervisor family. The TPS3613-01DGSR is designed to control output voltages in a wide range of applications that require both high current and low voltage levels. It has a small footprint, and its integrated features such as overvoltage protection, power-good signal, and internal comparator make it an ideal component for low-voltage powered PCBs. This article will discuss the application field and working principle of the TPS3613-01DGSR.

Application Field

The TPS3613-01DGSR can be used in a variety of applications, such as low-voltage powered PCBs, power-good signal controllers, and overvoltage protection. It also works well in applications requiring a robust supply voltage that can withstand high transient spikes and can be easily integrated into most commercial power supply designs. It provides accurate voltage tracking and can be adjusted to match the output voltage requirement.

TPS3613-01DGSR is also suitable for use in sensing current in automotive applications, such as pulse width modulation (PWM) controllers, and in motor control applications. It can be used in the power-up sequencing of automotive systems, providing protection against overvoltage and inrush current. This component is also suitable for use in data communication applications, providing both an enable/disable signal and a programmable frequency output.

In addition to these, the TPS3613-01DGSR is also useful in security applications, hand-held devices, and gaming consoles.

Working Principle

The TPS3613-01DGSR integrates several voltage regulators and pass transistors. The power-good signal output provides an indication to the system when a regulated output voltage has been reached. The internal comparator monitors the output voltage and compares it with a preset threshold. If the voltage rises above the threshold, the power-good signal is activated, signaling that the circuit is operating as designed. The power-good signal must be re-asserted after reset.

The TPS3613-01DGSR also contains two overvoltage protections. The first protection is designed to protect the system in the event of an overvoltage condition. The second protection is designed to prevent the system from experiencing an overtemperature condition. Both protections can be enabled or disabled through the use of an internal control register.

The core of the TPS3613-01DGSR is the voltage regulator, which is formed by the external components connected to the voltage regulator pins. The voltage regulator works in three operating modes: linear, hysteretic, or pulse-width modulation (PWM). Each of these operating modes is determined by the user-specified values for the current limit, voltage and frequency.

The voltage regulator provides a constant voltage output with a fast and accurate response. The output voltage is adjustable from 0.3V to 6V, and the tolerance of the output voltage is typically ±2%. The TPS3613-01DGSR is designed to provide a current limit of 50mA and can be programmed with a frequency range of 0.75 to 6MHz.

Conclusion

The TPS3613-01DGSR is a highly efficient and advanced PMIC-supervisor component. It is designed to provide efficient power management in a wide range of applications, including automotive, low-voltage powered PCBs, and data communication. The integrated features such as overvoltage protection, programmable frequency output, and power-good signal make the TPS3613-01DGSR an ideal choice for numerous applications.
