Constant Current Configuration #3: (PI3740-00-EVAL1 Board)
Low Side Current Sense and LGH
Current is sensed through R106 and, through a compensation network, fed into the LGH pin. This
is a low-side current sense configuration which requires only 4 components including the current
sense resistor.
Install jumpers as shown.
Install: J200 connecting R106 to R205/R206, JTRK, JISP and JISN shorting IS+ and IS- to ground.
Charging Current:
The charging current will be approximately 100mv/R106. If a standard resistor value
cannot be found that gives you the required current, use configuration #1.
