Accurately report lithium batteries and nickel consumption of power management products
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 batteries, or 6-12 Of nickel-hydrogen batteries and nickel-cadmium battery applications. New devices with smart laptop 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, 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 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 hp 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 battery current, temperature and voltage, but also directly connected to as many as four series lithium-ion or lithium-polymer Pavilion ZV5000 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 oscillator, 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 SMbus protocol with the host, and to support all Sbdata parameters.
Microchip for the PS501 Pavilion DV4000 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 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 Presario V2000 battery optimization, and provide PS501 applications such as custom programming and board and other adjustments Production support.
