9 / 19 page MC33341 http://onsemi.com 9 RS Load R1 Battery or Resistive Load Source Return Source R2 R3 Comp The above figure shows the MC33341 configured for source return low−side current sensing allowing a common power path between Source + and Load +. This configuration is especially suited for negative output applications where a common ground path, Source + to Load +, is desired. The Inverting Amplifier inputs, Pins 1 and 4, are used to sense the load induced voltage drop that appears across resistor RS. The internal voltage and current regulation thresholds are selected by the respective external connections of Pins 2 and 6. Resistor R3 is required in applications where high peak levels of inrush current are possible. The resistor value should be chosen to limit the negative substrate current to less than 20 mA. Excessively large values for R3 will degrade the current sensing accuracy.
