ZHCSMK7C November 2020 – December 2021 TPS2661
PRODUCTION DATA
TPS26611 or TPS26612 can be used for protection of UART IO lines as shown in Figure 9-17. The OUT pin voltage is monitored with respect to the +Vs/–Vs supply voltages. If the OUT voltage goes outside the +Vs/–Vs supply rails, the FETs cutoff the current conduction path and protects the whole system.
