Description

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 HS-

CAN 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.
