1. ALL SENSE RESISTORS TIE TO VEE AT ONE COMMON POINT. 2. VSSK CONNECTS TO THE COMMON SENSE RESISTOR VEE POINT THROUGH AN ISOLATED KELVIN SENSE TRACE. 3. ONE S1B PROTECTION DIODE FROM VEE TO OUTn AND ONE S1B PROTECTION DIODE FROM OUTn TO AGND SHOWN ON MOTHER BOARD. 4. ALL RESISTORS AND CAPACITORS ARE 0603. 5. OPTIONAL REPLACE R1- R8 WITH 10 OHMS AND D68 - D75 WITH BAT41JFILM FOR INCREASED SURGE PROTECTION.
