ZHCSMK7C November 2020 – December 2021 TPS2661
PRODUCTION DATA
The TPS2661x is an industrial current loop protector, providing a robust signal line protection in a wide range of industrial and automation systems. It is suitable for protection of all kinds of current loops like the 4–20-mA or ±20-mA current loops. TPS26610 is suitable for protection in current inputs whereas TPS26611 is suitable for protection in multiplexed V/I inputs.
TPS26612 is suitable for protection in power supply of two wire current transmitters. With disabled auto-retry time for first overload event, TPS26612 enables startup of power hungry transmitters requiring higher start up current for longer durations.
TPS26611 and TPS26612 devices can be also used to protect voltage outputs or digital communication signals like UART from miswiring of power supplies at these outputs. The device breaks the signal path by turning off the FETs when there is a voltage higher than supply voltage and thus keeping the system protected.
TPS2661x provides complete protection from industrial surge transients (IEC61000-4-5) and provides immunity from industrial fast transients (IEC610000-4-4) for signal lines.
