MC13783VK5

Application Field and Working Principle

MC13783VK5 belongs to a power management integrated circuit (PMIC) device family categorized as Specialized. It is designed to provide the functionality to manage power control and system monitoring in portable devices. It is a highly-integrated device featuring 14 power management functions and 8 general-purpose output pins.

Application Field

The MC13783VK5 is ideal for applications in mobile phones and portable media players, electronic gaming systems, wrist watches, appliances, and digital cameras among others. It is a highly-integrated device that can be used to simplify power management design, consisting of step-up converter, DC-DC converters, PowerPath control, sequencing, sequencing, LDOs, reset generation, A/D converter monitor, and SPI/I2C serial interfaces, among others.

Power Management Functions

The MC13783VK5 provides a number of key power management functions to efficiently manage energy sources, including PowerPath control and sequencing, buck converter, 4 LDOs, step-up converter, two DC-DC converters, voltage supervisor, power DETection, SPI/I2C serial interface, and A/D converter monitor.

PowerPath Control and Sequencing

The MC13783VK5 features PowerPath control and sequencing, enabling a fully flexible system setup which allows for configuring power sources in any sequence and for setting up the charging system for different battery types and levels. PowerPath control includes automatic regulation of primary and secondary power supplies, voltage regulation, emergency shutdown, and over temperature protection.

Buck Converter

The buck converter supplies a regulated voltage for the device, including the I/O circuits, the processor, and the flash memory. The MC13783VK5 offers a 16-bit programmable buck controller, which accurately regulates the system voltage, offering excellent dynamic response.

LDOs

The MC13783VK5 offers four LDO regulators, each with an adjustable output voltage of up to 3.2 V. These offer a stable voltage source, which is suitable for a wide range of applications. The LDOs provide an enable pin, allowing them to be controlled by an external signal, reducing power consumption when not in use.

Step-up Converter

The MC13783VK5 features an adjustable step-up converter, which is used to generate an output voltage of up to 3.6 V from a battery as low as 1.2 V. The converter features efficient operation, low power consumption, and excellent line regulation capabilities, providing a stable output voltage for the processor and other devices to ensure proper system operation.

DC-DC Converters

The MC13783VK5 integrates two DC-DC converters, each equipped with an adjustable output voltage of up to 3.2 V and an adjustable current limit of up to 3.2A. These offer highly undesirable regulation characteristics and a wide range of operating voltages, ideal for powering loads such as radios and other high-power devices.

Voltage Supervisor and Power Detection

The voltage supervisor monitors the voltage of the battery, enabling the system to be shut down if a critical voltage is reached. The power detection feature monitors the state of the power sources, allowing the system to be shut down in the event of an unexpected change in the power supply.

SPI/I2C Serial Interface

The MC13783VK5 features an SPI/I2C serial interface, offering the flexibility to communicate with different peripheral devices. The GPOs and GPs can be programmed and controlled through this interface, allowing customization of the system power sequence and status.

A/D Converter Monitor

The A/D converter monitor feature enables the system to sample and convert analog signals, making it suitable for measuring the battery voltage, temperature, and process variations.

Conclusion

The MC13783VK5 is a highly integrated Specialized PMIC designed to offer a range of power management functions, including buck converter, step-up converter, four LDO regulators, two DC-DC converters, voltage supervisor, power detection, SPI/I2C serial interface, and A/D converter monitor. This device is especially suited for mobile phones and portable media players, electronic gaming systems, wrist watches, appliances, and digital cameras.
