The PMP4397 is a battery charger module reference design suitable for 2-cell battery applications with a DC input of 4.5V – 15V. Detailed data for radiated emissions compliance is provided. The cell number could be trimmed by resistors over a range from 1-cell to 3-cells. A typical application is for 2-cells (8.4V/2000mAH).

  • Fully tested to comply with the industrial requirement (EN55022 CLASS B)
  • Single chip for battery charge & outputs
  • Protection includes the Input UVP, Input OVP, output OCP and OTP
  • Flexible configuration of output requirements by setting resistors
  • Good thermal performance with low component count
  • Small dimensions: 33mm x 50mm x 10mm
