2.3 Header Information

As outlined in Table 3-1, header J1 provides connections to the low-voltage side of the SENSE capacitors (corresponding to the SENSE pins of the IC), the low-voltage side of the inject capacitor, the IC bias power supply (VDD and GND pins), which is set between 8 V and 16 V, and a remote enable (EN) signal.

Table 2-1 J1 Header Connections
POSITION(1) LABEL DESCRIPTION
1 EN Enable input – leave open or tie high to enable the IC; tie to GND to disable
2 VDD Supply voltage connection – connect to a 12-V bias power supply referenced to GND(2)
3 INJ Inject output – connect to a Y-rated inject capacitor, CINJ
4 GND Ground – connect to the chassis ground of the system with a direct, low-inductance connection
5 S1 Sense 1 input – connect to a Y-rated sense capacitor, CSEN1
6 S2 Sense 2 input – connect to a Y-rated sense capacitor, CSEN2
(1) Pin positions of header J1 are designated right to left when viewed from the top side of the EVM.
(2) Working at an ESD-protected workstation, verify that any wrist straps, bootstraps or mats are connected and referencing the user to Earth ground before power is applied to the EVM.

A 6-pin right-angle header, part number TSW-106-08-G-S-RA, connects the EVM to a corresponding female receptacle, part number SSW-106-01-G-S, which mounts on the EMI filter board that carries the passive filter components – the CM chokes, X-capacitors and Y-capacitors – as well as the sense and inject capacitors. The EVM includes both the header and the receptacle, manufactured by Samtec. See Section 4.2.
