Overview

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.

Features:

  • Ultra Low Quiescent Current: 10 uA.
  • Wide Input Voltage Range: 0.9 V to 4.5 V.
  • 90 mA IOUT at 1.3 V Input (SP6641A-3.3 V).
  • 100 mA IOUT at 2.0 V Input (SP6641A-5.0 V).
  • Current Limit Protection.
  • Thermal Shutdown Protection with Hysteresis.
  • Auxiliary Supply Control.
  • Internal 0.3 Ω NFET Switch Eliminates External FETs.
  • Kelvin Connection with 3.3 V Feedback.

Applications:

  • PDA's.
  • DSC's.
  • CD/MP3 Players.
  • Pagers.
  • Digital Cameras.
  • Portable Handheld Medical Devices.
