1 / 19 page www.SiliconStandard.com 1 of 19 SS6782G 9/21/2005 Rev.3.01 Charge Controller for Dual Batteries FEATURES DESCRIPTION Quick and easy testing for production. The SS6782G fast-charge controller is designed for intelligent sequential charging of dual NiMH and NiCd batteries without the risk of malfunction. After powering on, the SS6782G charging sequence gives priority to battery pack A, represented by input signals at the ATS and ABV pins, over battery pack B, represented by BTS and BBV pin signals. The SS6782G automatically switches to charging the standby battery pack after the battery pack being charged finishes charging or encounters a fault condition. - ∆V (-0.25%) detection, 0∆V (peak voltage timer) detection, and ∆T∆t detection are the primary methods employed by the SS6782G to terminate fast charge. The fast charge can also be cut off by maximum battery voltage and maximum battery temperature detection along with the safety timer to prevent charging under fault conditions of the charging system or the battery itself . Sequential charging control of two NiMH/NiCd Battery Packs. Reliable sequential fast charge control of dual NiMH and/or NiCd Battery Packs, even with a fluctuating charging current. Fast charge termination by: ∆T∆t, -∆V, 0∆V, safety timer, maximum temperature, or maximum voltage. Linearly adjustable safety timer and ∆T∆t detection slope line. Selectable battery voltage protection range. Selectable battery temperature protection mode. Protection against battery voltage and battery temperature faults. Selectable LED display mode for battery status. Five pulsed trickle charge modes. Discharge-before-charge function available to eliminate memory effect. Choice of 20-pin DIP or 20-pin SOP packages. APPLICATIONS Dual-Battery Fast Chargers for: Mobile Phones. Both ∆T∆t and -∆V detection methods have been proved powerful in terminating fast charging for NiMH and NiCd batteries. The SS6782G utilizes the combination of these two methods to make a reliable decision for ending fast charge and to avoid issues caused by using - ∆V detection alone under certain conditions. Fig. 1 shows an example of a charging curve of a battery charged by a fluctuating current from a NiMH battery charger which uses the SS6782G controller IC to achieve optimal charging. The ∆T∆t or -∆V detection cir- cuitry may be disabled independently for different applications, such as system-integrated chargers, chargers with varying charge current, or battery packs lacking a temperature-sensing thermistor.
