MC13892CJVLR2 Application Field and Working Principle

The MC13892CJVLR2 is an application specific integrated circuit (ASIC) designed to manage the power supply system of electronic devices, such as mobile phones and personal digital assistants (PDAs). It is part of a family of application specific power management integrated circuits (PMICs) designed by Freescale Semiconductor. These ICs are designed to provide an integrated power management solution that allows device designs to minimize system complexity and minimize cost. The MC13892CJVLR2 is the most recent addition to Freescale\'s PMIC family and is designed specifically for the mobile phone market.

The MC13892CJVLR2 combines all essential power management sub-systems on-chip, offering mobile phone designers the highest levels of device integration and performance available. This single-chip integrated solution allows for the integration of a read-only memory (ROM) with a 12-bit analog-to-digital converter (ADC), a wide range of input and output voltage regulators, a direct memory access controller (DMAC), a power detect controller, and a pulse-width modulation (PWM) controller. Its flexible and configurable design also provides for easy system integration. It can process multiple data types and is compatible with Freescale’s popular ZSP processor family.

The MC13892CJVLR2 combines the features of analog and digital power management sub-systems. The analog part of the device is responsible for voltage and current regulation, while the digital part takes care of memory and data management. The device can monitor and control the voltages supplied to various circuit components. It can also detect and respond to overload conditions and it can generate error signals when a system fault occurs.

The MC13892CJVLR2 offers comprehensive power management features and numerous configuration options, making it ideal for use in a variety of applications. It provides for an extended operational temperature range, high current handling capacity, and low dropout operation. The device supports a wide range of input voltages from 1.0V to 5.5V and offers an adjustable maximum voltage limit. The device also integrates several current sensing and protection features, including power fail, soft start, and over-voltage and over-current protection. A built-in programmable pulse-width modulation (PWM) controller is also provided for dynamic voltage and current control.

The MC13892CJVLR2 allows for the integration of all necessary power management functions into one device. This integrated power management solution eliminates the need for multiple voltage and current regulators and reduces the need for PCB area. The device is fully configurable, which allows engineers to customize solutions to meet specific application requirements. This single-chip power solution offers low power consumption and high performance, making it a great choice for cost-sensitive, space-constrained applications.
