... And finally, the EMC1404 and EMC1424 each monitor one internal diode and up to three externally connected temperature diodes. All of the modes and functions of the EMC140X/2X can be tested and observed with the EVB- EMC14XX. The EVB-EMC14XX is a USB-based platform for evaluating all variations of the EMC140X/2X. A block diagram of this EVB is shown in 1.1 ...

... EMC1422 EMC1423 EMC1424 The remote diode on board the EVB-EMC14XX has an in-line series resistance adjustment. Checking the REC (Resistance Error Correction) feature of the EMC1402 is accomplished by setting the jumper on JP16 as shown in the diode connection. To return to 0 ohm series resistance, replace the jumper on JP16. This feature Revision 1 ...
