P21XX Powerharvester® Chipset Reference Design

Evaluation Board

BT1 is a connection point used for charging a high impedance storage element (cell resistance >25

ohms) such as thin-film batteries or super capacitors. The cell impedance of these types of batteries

will limit the current drawn from the P21XXCSR-EVB.

BT2 is a connection point used for charging a low impedance battery such as Li-ion or Alkaline

rechargeable. Resistor R7 is in series with this connection to limit current flow between the output

switch and the battery.
