Description
Doc ID 13518 Rev 5
2.15
Operational amplifiers
The operational amplifiers are especially designed to be used for sensing and amplifying the
voltage drop across ground connected shunt resistors. Therefore the input common mode
range includes - 0.2 ... 3V.
The operational amplifiers are designed for GND + 3V... GND – 0.2V input voltage swing
and rail-to-rail output voltage range. All Pins (positive, negative and outputs ) are available
to be able to operate in non-inverting and inverting mode. Both operational amplifiers are
on-chip compensated for stability over the whole operating range within the defined load
impedance.

Lin master pull up
A dedicated built-in switch “Tsw” enables the LIN to act as a master. (see chapter 2.18)

LIN bus interface
General requirements:
●
Speed communication up to 20kbit/s
●
LIN 2.0 compliant (SAEJ2602 compatible) transceiver
●
Function range from +40V to -18V DC at LIN Pin
●
GND disconnection fail safe at module level
●
Off mode: does not disturb network
●
GND shift operation at system level
●
Microcontroller Interface with CMOS compatible I/O pins.
●
Pull up resistor internal.
●
ESD: immunity against automotive transients per ISO7637 specification (see
application note)
●
Matched output slopes and propagation delay
In order to further reduce the current consumption in standby mode, the integrated LIN bus
interface offers an ultra low current consumption.
