This document contains information for TLV3601 (DCK and DBV packages) and TLV3602 (DGK and DSG packages) to aid in a functional safety system design. Information provided are:
Figure 1-1 shows the device functional block diagram of single channel for reference.
TLV3601 and TLV3602 were developed using a quality-managed development process, but was not developed in accordance with the IEC 61508 or ISO 26262 standards.
ADVANCE INFORMATION for preproduction products; subject to change without notice.
This section provides Functional Safety Failure In Time (FIT) rates for the DCK and DBV packages of TLV3601 and DGK and DSG packages of TLV3602 based on two different industry-wide used reliability standards:
FIT IEC TR 62380 / ISO 26262 | DCK FIT (Failures Per 109 Hours) | DBV FIT (Failures Per 109 Hours) |
---|---|---|
Total Component FIT Rate |

The failure rate and mission profile information in Table 2-1 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:
Table | Category | Reference FIT Rate | Reference Virtual TJ |
---|---|---|---|
4 | CMOS, BICMOS Digital, analog / mixed | 12 FIT | 55°C |
The Reference FIT Rate and Reference Virtual TJ (junction temperature) in Table 2-3 come from the Siemens Norm SN 29500-2 tables 1 through 5. Failure rates under operating conditions are calculated from the reference failure rate and virtual junction temperature using conversion information in SN 29500-2 section 4.
