IL33290D
MICROCIRCUIT ISO of K Line INTERFACE
DESCRIPTION
IL33290D – microcircuit of the serial interface, intended for ensuring the dual direction semi-
duplex connection in the automotive diagnostic applications. The microcircuit is designed to ensure
communication between the vehicle-borne microcontroller of the transport means and the external
systems via the special line ISO K. The microcircuit IL33290D is designed in compliance with
Specification of the diagnostic systems ISO9141. The microcircuit output, controlling line K, is
protected from short circuit and temperature overshoot.
Serviceability of the microcircuit in the wide range of temperatires
and supply voltages is ensured by its fabrication under the
BiCDMOS process, combining the CMOS logic, bipolar and MOS
analogue circuit solutions and powerful DMOS transistors.
Microcircuit IL33290D is mainly intended for the automotive
Plastic package
applications, but is also applicable in other applications with the
MS-012AA (SO-8)
serial connection. The microcircuit parameters are specified for the – Identification of microcircuit
ambient temperature range of -40 C TA 125 C and the supply
IL33290D in package
battery voltage range of 8.0 V UBB 18 V. The microcircuit
IL33290D is fabricated in the economic mass production package
MS-012AA.
Main functional features:
- operational in the wide voltage range of the supply battery from 8 to 18 V;
- operating ambient temperature is from minus 40 to plus 125 C;
- compatible with the standard CMOS logic;
- ISO K line pin is protected from short circuit to the ground;
- heat protection with hysteresis;
- possibility of letting large value currents via the connection pin to the ISO K bus;
- possibility of controlling the bus with the parasitic capacitance up to 10 nF;
- protection from influence of the static electricity up to 8.0 kV, attained by application of the
several additional components;
- in the mode “ stand-by ” non-availability of the current consumption from the battery at UDD = 5 V;
- low current consumption in the process of operation at UDD = 5 V.
