1/27/2004 - Microchip Technology (Nasdaq: MCHP), a leading provider of microcontroller and analog semiconductors, announced the PS700 battery monitor that provides precise battery information needed to calculate the battery capacity. Targeted for hand-held and mobile products, the PS700 supports battery-operated products to extend system run times while providing greater predictability of use. The device sets expectations of runtime, charge time and battery state of health; meanwhile, it accurately monitors and reports current operational conditions and status of the battery for use in system power management.
Microchip’s PS700 battery monitor integrates a precision, programmable, A/D converter with 4K bits of EEPROM and a SMBus interface. In addition the device eliminates the need for external components by incorporating a temperature sensor and regulator.
For flexibility during changing operating conditions, the A/D converter can be configured to provide measurements of parameters such as voltage, current and temperature with resolutions of 9-16 bits. Battery information is provided to the host over an industry-standard SMBus interface while battery and user data is stored within the onboard 4K-bit EEPROM. The PS700 can utilize an onboard or external temperature sensor for use in determining battery temperature. Designers using the PS700 have the ability to achieve precise predictions of battery capacity and current operational conditions, which results in longer run time and better overall system-power management.
In support of low-power applications, the PS700 operates in four different power modes. This device consumes less than 80 microamps in run mode and less than one micro-amp in sleep mode. The PS700 supports 1- and 2- cell Lithium (Li) batteries and 3-to-6-cell Nickel Metal Hydride (NiMH) battery backs. Batteries enabled with the PS700, can stop over-charge and over-discharge, predict run time, or time to charge, and provide accurate, real-time battery information for use by the system or system user.
Microchip Technology offers an evaluation kit PS7070EV, which includes PS7070 evaluation board, PS700 IC, PS070 PowerMateTM device programmer and PS051 PowerInfoTM2 interface board, USB cable and documentation.
Pricing for the PS700 in 1,000-unit quantities is $1.45 USD each in the 8-pin TSSOP. Samples are available now and volume production is scheduled for February 2004. For more information, contact any Microchip sales representative or authorized worldwide distributor.
