Description

General part information

ISO7741 Series

The ISO7741E-Q1 automotive device is a grade 0, high-performance, quad-channel digital isolator with 5000VRMS isolation ratings per UL 1577. This device has reinforced insulation ratings according to VDE, CSA, TUV and CQC. With a high temperature range of up to 150°C, the device is designed for applications like belt starter generators, water, pumps, cooling fans, soot sensors, and more which can experience ambient temperatures greater than 125°C.

The ISO7741E-Q1 device provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. This device comes with enable pins which can be used to put the respective outputs in high impedance for multi-controller driving applications and to reduce power consumption. The ISO7741E-Q1 device has three forward and one reverse-direction channels. If the input power or signal is lost, default output is high for devices without suffix F and low for devices with suffix F. See the Device Functional Modes section for further details.

Used in conjunction with isolated power supplies, these devices help prevent noise currents on data buses, such as CAN, or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through remarkable chip design and layout techniques, electromagnetic compatibility of the ISO7741E-Q1 device is significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO7741E-Q1 device is available in 16-pin SOIC package.
