PMICs, or Power Management Integrated Circuits, are powerful devices used to control and regulate the complicated power of modern electronics. They help manage the complex electrical patterns that power up and communicate with devices, making them essential components for any modern circuit board. The DS1833Z-10+ is a PMIC supervisor from Dallas Semiconductor that offers features specifically tailored to the needs of battery-powered devices. This article will discuss the application field and working principle of the DS1833Z-10+.

Application Field

The DS1833Z-10+ offers a host of features that make it ideal for many applications where power management is essential. The device is designed to be used in wireless sensor nodes, point of sale systems, remote control systems, and other low-power battery applications. It is also ideal for low-voltage, 3-terminal linear regulator designs. Its size makes it a perfect fit for handheld or portable devices.

The DS1833Z-10+ provides a low quiescent current, making it perfect for low-power applications. It has a high accuracy reset threshold and guarantees reset accuracy to ±1.1% of Vdd. Additionally, it has an adjustable watchdog timer and can detect any momentary power failures. All together, these features make the DS1833Z-10+ an excellent choice for applications where power management is critical.

Working Principle

The DS1833Z-10+ is a 3-terminal PMIC supervisor with an adjustable reset/WATCHDOG output. It monitors and regulates the output of the power supply of the device by comparing the input voltage to a pre-set threshold voltage. If the input voltage drops below the threshold value the output activates the reset or WATCHDOG signal.

The DS1833Z-10+ has an adjustable reset/WATCHDOG timeout. If a power failure occurs, the adjustable WATCHDOG timer will wait a certain amount of time before the reset/WATCHDOG output is activated. This time can be set by the user to monitor any power failure or short. Additionally, the DS1833Z-10+ has a wide operating range, making it suitable for a variety of battery operated applications.

The DS1833Z-10+ also has a power-on reset (POR) function, which enables the device to detect power loss and initiate a reset. It has an adjustable reset threshold which allows the user to select the voltage at which the reset signal is triggered. The DS1833Z-10+ also protects against power supply transients, providing circuit system stability.

Conclusion

The DS1833Z-10+ is an ideal choice for a variety of low-power applications, from wireless sensor nodes to point of sale systems. Its low quiescent current and adjustable reset/WATCHDOG timeout make it perfect for battery-powered applications. Additionally, its adjustable reset threshold and power-on reset (POR) function ensure that the device is protected during power failures or transients. All together, the DS1833Z-10+ is the perfect solution for applications where power management is critical.
