and programming modes, excellent ESD robustness, immunity against disturbance, and radiated emission performance. They
have safe behavior, in case of a LIN bus short-to-ground, or a LIN bus leakage during low power mode.
POWER SUPPLY PIN (VSUP)
through a serial diode, for reverse battery protection. The DC operating voltage is from 7.0 to 18 V. This pin sustains standard
automotive condition, such as 40 V during load dump. To avoid a false bus message, an under-voltage on VSUP disables the
transmission path (from TXD to LIN) when V
LIN Module.
GROUND PIN (GND)
on the LIN bus pin when in the recessive state.
LIN BUS PIN (LIN1, LIN2)
compliant to the LIN bus specification 1.3, 2.0, 2.1, and SAEJ2602-2.
Transmitter Characteristics
diode structure is integrated, so no external pull-up components are required for the application in a slave node. An additional
pull-up resistor of 1.0 kΩ must be added when the interface is used in the master node.
The 33663 is tested according to the application conditions (i.e. in normal mode and recessive state during communication).

Analog Integrated Circuit Device Data
Freescale Semiconductor
The 33663L and 33663J are both a Physical Layer component dedicated to automotive LIN sub-bus applications.
The 33663L features include a 20 kbps baud rate and the 33663J a 10 kbps baud rate. Both integrate fast baud rate for test
Digital inputs are 5.0 and 3.3 V compatible without any external required components.
The INH1 and INH2 outputs may be used to control an external voltage regulator, or to drive a LIN bus pull-up resistor.
The VSUP supply pin is the power supply pin for the 33663L or 33663J. In an application, the pin is connected to a battery
In case of a ground disconnection at the module level, the 33663L and 33663J do not have significant current consumption
The LIN1 and LIN2 pins represent the single-wire bus transmitter and receiver. It is suited for automotive bus systems, and is
The LIN interface is only active during Normal mode.
The LIN driver is a low side MOSFET with internal over-current thermal shutdown. An internal pull-up resistor with a serial
The LIN pin exhibits no reverse current from the LIN bus line to V
The transmitter has a 20 kbps baud rate (Normal baud rate) for the 33663L and 33663S devices, or 10 kbps baud rate (Slow
