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.
