TLE9243QK
The TLE9243QK is an application specific multiple output system supply for transmission applications supplying 5 V-μC, transceivers, and sensors by an efficient and flexible pre-/post-regulator concept over a wide input voltage range.
Like other Application Specific PMICs, TLE9243QK is a power management IC that levers system cost optimization potential and FuSa harmonization for a specific application. The TLE9243QK offers the complete power supply functionality as well as application specific features for transmission systems.
Beside the power supply functions, the TLE9243QK provides sensor interfaces for three channels including one 9V LDO per channel as well as three channels to drive external n-channel power switches.
The TLE9243QK has been developed according to ISO 26262 targeting systems up to ASIL-D. Multiple safety features as window and functional watchdog and monitoring functions enable easy realization of ASIL-D together with the Infineon’s AURIX™ family and other microcontrollers as well.
The TLE9243QK is coming in a Grade 0 thermally enhanced LQFP-64 suitable for harsh environments.
