SLLSFQ8B December 2024 – December 2024 THVD9491-SEP
PRODUCTION DATA
The THVD9491-SEP driver is protected against any DC supply shorts in the range of -40V to +40V. The devices internally limit the short circuit current to ±250mA to comply with the TIA/EIA-485A standard. In addition, a fold-back current limiting circuit further reduces the driver short circuit current to less than ±5mA if the output fault voltage exceeds |±25V|.
The device features thermal shutdown protection that disables the driver and the receiver if the junction temperature exceeds the TSHDN threshold due to excessive power dissipation.
