Battery Charger NiCd, NiMH battery, 5.5V input, 5.5V / 2A charge, SOIC-16 Product Overview The BQ2004HSN is a switch-mode NiCd/NiMH Battery Charger with negative dV, peak voltage detection and dt/dt termination. This fast-charge IC provides comprehensive fast charge control functions together with high-speed switching power control circuitry on a monolithic CMOS device. Integration of closed-loop current control circuitry allows the BQ2004 to be the basis of a cost-effective solution for stand-alone and system-integrated chargers for batteries of one or more cells. Switch-activated discharge-before-charge allows based chargers to support battery conditioning and capacity determination. High-efficiency power conversion is accomplished using this charger as a hysteretic PWM controller for switch-mode regulation of the charging current. It may alternatively be used to gate as an externally regulated charging current. Fast charge may begin on application of the charging supply, replacement of the battery, or switch depression. Fast-charge and conditioning of nickel cadmium or nickel-metal hydride batteries Hysteretic PWM switch-mode current regulation or gated control of an external regulator Easily integrated into systems or used as a stand-alone charger Pre-charge qualification of temperature and voltage Configurable, direct LED outputs display battery and charge status Optional top-off charge and pulsed current maintenance charging Logic-level controlled low-power mode Green product and no Sb/Br Applications Power Management Product Information Battery Type: NiCd, NiMH Input Voltage: 5.5V Battery Charge Voltage: 5.5V Charge Current Max: 2A Battery IC Case Style: SOIC No. of Pins: 16Pins Operating Temperature Min: -20°C Operating Temperature Max: 70°C MSL: MSL 1 - Unlimited
