41 / 70 page  DocID029344 Rev 2 41/70 STGAP1AS Functional description 70 7.14.4 SENSE resistor check The purpose of this security check is to verify the connection between the device and the sense shunt resistor and to verify the optional sense resistor filter network is not open. To perform this test, the following procedure has to be followed: Set SD = low Send StartConfig command Set SENSE_EN = '1' Set SNSCHK = '1' Send StopConfig command Wait tRchk + tSENSERchk Read SENSE flag – SENSE = '0' → OK (VSENSE < VSENSEth) – SENSE = '1' → FAIL (VSENSE > VSENSEth) During the check a small current ISENSERchk is sourced from the SENSE pin (see Figure 18 ). If the sense resistor is not present or floating, SENSE pin voltage will rise and once VSENSEth is exceeded, a SENSE fault will be reported in the STATUS1 register within tRchk. To ensure the check result, the following condition has to be verified: – The SENSE flag read has to be delayed of tSENSERchk, which is the time the customer filtering network and/or the power switch gate takes to reach VSENSEth by the ISENSERchk current. |
