The TI ISO7041FQDBQRQ1 is a four-channel, unidirectional digital isolator from the ISO7041-Q1 series, using capacitive coupling to transfer digital signals across a galvanic isolation barrier. It is rated for 3000 Vrms isolation and supports a data rate of 4 Mbps, with a wide supply range of 3 V to 5.5 V. Typical applications include isolating SPI, UART, or general-purpose digital I/O in battery management systems, motor drive control, and on-board chargers.
Propagation delay is 165 ns max in either direction; pulse-width distortion is 10 ns max. Common-mode transient immunity is 50 kV/µs.
The 16-SSOP package has a 3.90 mm body width. Supply voltage range is 3 V to 5.5 V.
