Segmentation power subsystem

Segmentation power subsystem



Many portable systems are generally based on several different parts of the structure or composition of district. In addition, each district may have its own set of power requirements laptop battery. These portable systems to meet the different needs of the individual often require specialized portable power chips.

Because of its electrical power output and low noise, dell laptop battery,linear regulators chips are usually installed in a portable system radio frequency (RF) in the district. Many linear regulators are open to provide rapid, and RF-conditioning needs of low-noise operation. There’s no need to ICP, they are very small in size, occupying only a small amount of board space.

In order to implement different lighting functions inspiron battery, such as: the camera flash digital cameras, portable cameras to provide continuous lighting or liquid crystal display and keypad of the backlight, may also be required number of DC / DC boost converter. An organic liquid crystal displays (organic light-emitting diode) of the bright colors may also require a certain level of voltage conversion.

Processor chip (including the general-purpose processors and digital signal processor (DSP)) have their own set of norms of power. dell 312-0386,Most processors are high-current, low-voltage devices, requirements to undergo a rigorous conditioning power. In order to be portable system down to 3.3 V power processor 1.2 V level, voltage converter is the most commonly used method. Usually, it 1691P requires a large current can provide a highly efficient DC / DC converters.

Of course, some highly complex system requirements Latitude D620, 312-0386, PC764, TD175, Latitude D820, Latitude D830, MM165, YD626, 312-0393 for portable power equipment for all or part of the power sub-system for monitoring and management. For example, the voltage monitoring device can monitor the power system, in response to some of the time of the incident to open or close the subsystem. A Power Management Unit (PMU) will be many possible by a number of discrete implementation of the power supply device functions into a single chip 75UYF . PC764,This integration cost savings, board space and design time.

Microchip introduced the integration of field-programmable power



A few days ago, microcontroller and analog semiconductor supplier Microchip Technology (micro-core technology companies in the United States) to further expand its lineup of battery management products, today announced the launch of the integration of field-programmable power, applicable to 2-4 lithium-ion and Lithium polymer laptop battery, or 6-12 nickel-hydrogen batteries and nickel-cadmium battery applications. New devices with smart battery system (Smart Battery System, called SBS), can accurately judge the battery power and provide battery monitoring function, improve the application of security, with the end-of-discharge (End of Discharge, called EOD) control,TD175, then extended Battery life and working hours.

PS501 battery management IC products used Microchip high-performance, low-power PIC18 microcontroller core, its 16 kilobytes of memory-chip memory in the Accuron ® patented algorithm.

The hp battery management devices of current low, only 150 microamps. When the suspension of work related applications, the device will automatically enter the low-power sleep mode, power consumption less than 1 microamp, both energy conservation and reduce excessive battery discharge.

The new device also integrates a 16 programmable Sigma-Delta ADC, as well as to optimize the professional application of mixed-signal circuits. As a result, the device can not only accurate measurement of Pavilion DV1000 battery current, temperature and voltage, but also directly connected to as many as four series lithium-ion or lithium-polymer battery pack. EEPROM device can be stored on the user and set up the system by “learning”, was the battery parameters. The device also has a precise silicon oscillatorLatitude D820, , no longer need an external crystal. The new device hardware and advanced algorithms will be combined balance of the battery, the device could well be applied to lithium-polymer battery applications.

The new device has 12-pin universal, support charge and safety control or user programmable digital I / O. The eight-pin can only be used for light-emitting diode driver, while another two to make a direct FET (FET) drive the open-drain. The device can be industry-standard Pavilion ZV5000 battery SMbus protocol with the host, and to support all Sbdata parameters.

Microchip for the PS501 battery management products provide a wide range of system development. One for lithium-ion or lithium-polymer battery, Microchip launched a series for four batteries of the PS5164EV, three batteries Latitude D620, 312-0386, PC764, TD175, Latitude D820, Latitude D830, MM165, YD626, 312-0393 of the series and two series PS5163EV battery PS5162EV; for nickel-hydrogen batteries and nickel-cadmium batteries, used to launch 6-12 series battery PS5100EV. These systems include the development of an application board, PowerInfoTM 2 interface board (PS051) and fringe of the cable, and documentation. In addition, the support of Microsoft Windows ® PowerToolTM 2 (PS050) software built-in wizard procedures to facilitate the assessment of engineers in the development of systems and application-specific parameters and Pavilion DV4000 battery optimization,Latitude D830, and provide PS501 applications such as custom programming and board and other adjustments Production support.
