Modern electronic applications continue to see an increase in the number and variety of functional electronic blocks for the applications. It has become increasingly difficult to reduce the number of integrated devices required to support a particular application. STWBC-EP devices incorporate power blocks and system-on-chips that can significantly reduce the number of components, enabling devices to be more easily integrated into single systems. This article provides an overview of the STWBC-EP application field and its working principle.

Description of STWBC-EP

STWBC-EP is an acronym for “System-on-Chip (SoC) with high level power control blocks”. It is a power management integrated circuit (PMIC) that combines multiple analog and digital blocks on a single chip. It is a highly integrated device for providing power control, conversion and protection for a wide range of electronic systems such as medical, automotive, industrial, home appliances, aerospace and others. The power converter blocks of the device provide DC-DC conversion and control for a wide range of input and output voltages. The power control blocks provide power sequencing, overload protection, system monitoring and safety, and status information.

Application Fields of STWBC-EP

STWBC-EP devices are typically used in a wide range of system-on-chip (SoC) and portable applications. The integrated power blocks enable the device to be used in a wide range of applications including automotive, clock and DC to DC applications. These devices provide a highly efficient power solution, with a wide range of features and flexibility, making them ideal for several different types of applications.

The STWBC-EP can be used in automotive applications such as vehicle infotainment systems, navigation systems, remote energy management, HVAC systems, and powertrain control. In these applications, the device provides a highly efficient power solution in a small form factor, with proven reliability and low thermal dissipation. By integrating many of the parts required for automotive applications, such as the DC–DC converter, voltage regulator, and power protection, the STWBC-EP can reduce the overall system cost and increase reliability.

The STWBC-EP can also be used in clock applications, providing low power and accurate clocking solutions. This is made possible thanks to the integrated voltage-programmable oscillator, which allows precise timing adjustments to be easily made. In addition, the STWBC-EP has an integrated reset control, allowing for precise system resets, even when the main power supply is removed. The device also provides an integrated power-on reset circuit and a watchdog timer, further enhancing system reliability.

The STWBC-EP also provides DC to DC conversion, allowing for efficient conversion from one voltage level to another. This is useful in applications such as battery charging, where precise control of the output voltage is required. The device also has a wide range of protections, such as current limit, thermal shutdown, output short-circuit protection, and voltage monitoring, to ensure reliable operation under harsh conditions.

Working Principle of STWBC-EP

The STWBC-EP combines several power blocks and system-on-chip (SoC) on a single chip, allowing for the development of highly integrated systems. The power blocks include one or more voltage regulator, DC-DC converter, voltage detector, reset control, watchdog timer, and power supply sequencer. The system-on-chip includes a CPU, system memory, peripheral interfaces, communication interfaces, and other support components.

The voltage regulator block supports a wide range of output voltages from 2.2V to 45V. It provides a highly accurate output voltage, with low output voltage ripple, and can either be used to power the system directly, or to regulate the output of the DC-DC converter. The DC–DC converter block is capable of providing DC–DC conversion for a wide range of input and output voltages. It is designed to work with switching frequencies up to 11MHz, and can operate with effeciencies up to 95%.

The voltage detector block is designed to detect a low or high power supply voltage, and can be used to provide an early warning system for system failure. The reset control block provides an advanced reset control circuit that can be used to reset the system under various conditions. The watchdog timer block provides an additional layer of system control, and can be used to reset the system when it has hung or crashed.

The power sequencer block provides an easy-to-use interface for connecting multiple power switches and power monitoring blocks, allowing for easy power control and monitoring of the system. This allows for the system to be powered up in a safe and efficient manner. The system-on-chip block provides CPU and memory, as well as peripheral and communication interfaces, allowing devices to be more easily integrated into single systems.

Conclusion

The STWBC-EP is a highly integrated power management device, providing a wide range of integrated blocks needed for a wide range of applications. The device offers highly efficient power solutions, with a wide range of features and flexibility, making it an ideal choice for various system-on-chip and portable applications. The power blocks, including voltage regulator, DC-DC converter, voltage detector, reset control, watchdog timer, and power sequencer, make the device highly reliable and capable of working in harsh conditions. In addition, the integrated system-on-chip block makes it easier to integrate the device into single systems. The STWBC-EP provides a simple, efficient, and cost effective solution for power management.
