DS4510U-15+T&R

DS4510U-15+T&R is a popular digital supervisor used in PMIC (Power Management ICs). It offers a wide range of features and applications with a great level of performance. This article will describe the application fields and working principles of this IC.

Principle of Operation

DS4510U-15+T&R is based on a CMOS architecture that combines voltage regulation and supervision functions for power management. It has two input voltage monitoring pins (VIN1 and VIN2), two output voltage regulation pins (VOUT1 and VOUT2), one reset control pin (RST) and three output pins (F1, F2 and F3). The voltage monitoring pins are used to detect the presence of supply voltages and to prevent reset operation when a certain voltage is applied.

The reset control pin (RST) is used to control the reset logic. This pin must be in an "active" state for the circuit to operate correctly. When the RST pin is in an inactive state, the supervisor will initiate a reset sequence. The supervisor also offers protection against an over-voltage fault (OVF1) and an under-voltage fault (UVF1) when the voltage monitoring pins VIN1 and VIN2 have an input voltage greater or lower than a certain threshold.

The output pins (F1, F2, F3) are used to indicate status: F1 is used to signal an under-voltage fault (UVF1) and an over-voltage fault (OVF1). F2 is used to signal a power-good signal while F3 is used to indicate the reset output.

Applications

DS4510U-15+T&R is used in various application fields due to its versatility. It is used in power supplies, battery chargers, microprocessor-based systems and DSPs. The IC also offers protection against over-voltage, under-voltage and power-good signals.

In addition, the IC is used in hand-held devices such as laptops, smartphone and tablets. The IC is used to provide a safe and reliable power management, by monitoring the supply voltage and cutting it off when it passes a certain threshold. It also helps ensure that the device will not be damaged in cases of over-voltage.

The IC is also used for safety critical applications such as medical equipment and military systems. Here, it is used to ensure a constant voltage and to prevent any accidental over-current. As the IC also has an input voltage monitoring pin, it can prevent any reset operation when the voltage level drops below a certain threshold.

Conclusion

In conclusion, DS4510U-15+T&R is a versatile digital supervisor used in PMICs. Its wide range of features, applications and performance make it suitable for a variety of applications, from power supplies and battery chargers to hand-held devices and medical equipment. The supervisor offers protection against over-voltage, under-voltage and power-good signals, while the input voltage monitoring pin prevents any reset operation in cases of excessively low voltages.
