TLE9744QKXUMA1

TLE9744QKXUMA1 is an Infineon Technologies OPTIREG PMIC in a PG-LQFP-64 package, purpose-built as the safety power companion for automotive traction inverters driving AURIX TC2x, TC3x and TC4x or TRAVEO T1G controllers. From a 4 to 36 V input it generates the system rails with two buck-boost pre-regulators, linear post-regulators for the microcontroller, transceiver and ADC reference, and two sensor-supply trackers, at just 50 µA quiescent current. An integrated resolver exciter removes a separate excitation IC, and the safety engine (ISL) evaluates six analog inputs, five digital inputs, functional and window watchdogs and microcontroller supervision to force a safe state on failure - supporting ISO 26262 systems up to ASIL D. Infineon lists the OPN as active and preferred with longevity planned to 2039, over -40°C to +150°C. Selection advice: this is an application-specific safety PMIC, not a general multi-rail part - its value lands when the inverter safety case needs the integrated monitoring and safe-state logic. Parameters verified against Infineon Technologies documentation.
