TLE7368-3E - Common Failure Power IC for Transmission Control Unit (TCU), Automotive Grade

The TLE7368-3E is a dedicated multi-rail power supply IC designed for automotive transmission control units.

It is widely recognized as a common failure component in TCU assemblies due to continuous thermal and electrical stress.

This chip provides three regulated output voltages for microcontrollers, sensors, and CAN transceivers.

It includes integrated power sequencing, reset generation, and watchdog functionality for system reliability.

Designed for 12V automotive electrical systems, including passenger cars with automatic or dual-clutch transmissions.

Operating temperature range from -40°C to +150°C, suitable for transmission-mounted or under-hood installations.

Features overcurrent, overtemperature, and short-circuit protection to prevent cascading board failures.

Low quiescent current reduces battery drain during vehicle sleep mode.

The device monitors input voltage and generates system reset during undervoltage or overvoltage events.

This IC is a frequent replacement part for TCUs experiencing intermittent communication loss or shift errors.

It reduces external component count, simplifying PCB layout for transmission module repairs.

Compatible with multiple European and Asian vehicle platforms using similar TCU architectures.

Direct drop-in replacement for failed original power ICs on damaged transmission computer boards.

AEC-Q100 qualified, ensuring long-term durability in vibration-rich and high-temperature environments.

Packaged in a thermally enhanced PG-DSO-36 for efficient heat dissipation and automated assembly.
