概述

Description

ISO1042QDWRQ1 is an automotive-grade digital isolator from TI’s ISO1042 family. It provides four isolated digital data paths between two power domains (VDD1 and VDD2), offering galvanic isolation to protect low-voltage logic from high-voltage or noisy circuitry. The Q1 suffix indicates automotive qualification (AEC-Q100). Key benefits include independent supplies, isolation for safety and reliability, protection from transients, and relatively fast signal propagation with good noise immunity. Typical uses are isolating control signals (SPI/I2C/UART, general I/O) between a microcontroller and high-voltage sensors, actuators, or motor drivers in automotive and industrial applications. In short: a quad-channel, automotive-rated digital isolator that enables safe, reliable signal transfer across a barrier between two voltage domains.

Package

QFN (WQFN) package — 16 pins, 4×4 mm, with an exposed pad.

Pinout

Pin count: 16 pins.
Function: Isolated RS-485/RS-422 transceiver (one channel) with DI/RO data pins and DE/RE control. Provides galvanic isolation between the logic side and the bus side via dual supplies (VCC1/GND1 and VCC2/GND2) and A/B differential bus on the isolated side.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- Company type: American multinational semiconductor company that designs and manufactures a wide range of analog and digital integrated circuits and embedded processing products.

Application

ISO1042QDWRQ1 is a 2-channel isolated digital I/O transceiver (automotive grade). It provides galvanic isolation for logic signals, letting data cross high-voltage/noisy environments safely. Typical applications: automotive ECUs and body electronics, sensor/actuator interfaces, motor drives and power electronics, industrial automation (PLC and isolated sensors/controls), and renewable energy systems.
