• Datasheet

The TLE 7263E is a monolithic integrated circuit in an enhanced power package. The IC is designed for CAN-LIN gateway applications.

To support these applications the TLE 7263E covers smart power functions such as HSCAN transceiver and LIN transceiver for data transmission, dual low dropout voltage regulator (LDO) for external 5 V supply, and high-side switch as well as a 16-bit SPI (serial peripheral interface) to control and monitor the IC. There is also a window watchdog circuit with a reset feature, a fail-safe output, a voltage sensing input and a undervoltage reset feature implemented.

The device offer low power modes in order to support modules directly connected to the battery (KL. 30). A wake-up from the low power mode is possible via a message on the bus or via the bi level sensitive monitoring/wake-up inputs. The integrated High-Side switch can also be used to periodically supply an external wake-up circuitry in the low power mode, by choosing a special function. The integrated bus transceivers offer a receive-only mode for software diagnosis functions. The IC is designed to withstand the severe conditions of automotive applications.
