Product Highlight

  • Type: Battery Management
  • Core Supported: SP6641

Exar's PowerXR products fuse digital power-supply control and monitoring technology with high-performance analog circuitry in a new generation of digital power-management products that enable system architects to create products with advanced, integrated, switching power supplies that significantly reduce wasted energy compared to more commonly used linear power-supply regulators.

The SP6641 is an ultra-low quiescent current, high efficiency, DC-DC boost converter designed for single and dual cell alkaline, or Li-ion battery applications found in PDA’s, MP3 players, and other handheld portable devices. The SP6641 features a 10 μA quiescent current, a 0.3 Ω Nchannel charging switch, 0.9 V input startup, and a 0.33 A or 1.0 A inductor current limiting feature.The SP6641 is offered in a 5 pin SOT-23 package and provides an extremely small power supply footprint optimized for portable applications. The SP6641 is preset to 3.3 V and can be controlled by a 1 nA active LOW shutdown pin.
