- Battery Protection IC for 1-cell Batteries Complements Successful Precursor Series
The new battery protection IC series S-8200A from Seiko Instruments Inc. is demonstrating that the requirement for higher precision in the overcharge- overdischarge- and overcurrent- supervision and lower power consumption are not necessarily a contradiction. The pin compatibility of the SOT-23-6 and SNT-6A packages provide exchangeability with the precursor series S-8261 and S-8211.
In the case of existing designs this circumstance is not only increasing the safety of availability of alternative components but is also providing an improvement of the technical parameters. Higher precision of overcharge-detection-voltage-accuracy, +/-25mV versus +/-35mV and overdischarge-detection-voltage-accuracy, +/-35mV versus +/-50mV…+/-80mV for all precursor series applies for the S-8200A. It is similarly applicable for discharge-overcurrent-detection-voltage-accuracy +/-10mV versus +/-15mV…+/-20mV, load-short-circuit-detection-voltage-accuracy +/-100mV versus +/-200mV…+/-400mV and charge-overcurrent-detection-voltage-accuracy, +/-15mV versus formerly +/-30mV. Current consumption of 100nA in power-down-mode is only half the requirement of the S-8211 Series. The typical current consumption is 2.8mikroA in active mode, precursor series needed 3.5mikroA. Specified maximum is 5.0mikroA, distinguishing S-8200A from its precursors with 5.5mikroA…7.0mikroA. Only two resistors, one capacitor and two N-MOS-FET power switches are the external components needed to turn S-8200A into a reliable, precise and energy-efficient single cell Li-Ion battery protection system. The tiny packages, SOT-23-6 or SNT-6A of merely 1.6mmx1.8mmx0.5mm permit extraordinary packing density and therefore enable the integration of the protection circuitry within most of the battery pack without own space requirement.
