Frequently Asked Questions
What makes the ISO7761FDBQR different from the ISO7761DBQR?
The ISO7761FDBQR (F suffix) provides reinforced galvanic isolation, typically rated at 5000 Vrms, while the D-suffix variant provides basic or functional isolation. Reinforced isolation means the device meets the requirements for use in safety-critical systems where a single barrier must protect against hazardous voltages without requiring additional external isolation.
What channel configuration does the ISO7761FDBQR have?
The ISO7761FDBQR features a 6/1 bidirectional channel configuration: six channels transmit signals in the forward direction across the isolation barrier, and one channel carries a signal in the reverse direction. This configuration suits applications like gate driver circuits where control signals flow forward and fault feedback flows back.
What data rate does the ISO7761FDBQR support per channel?
Each channel of the ISO7761FDBQR supports data rates up to 100 Mbps, making it suitable for high-speed isolated digital communication such as gate drive PWM signals, encoder data, and high-speed serial interfaces used in motor control and power conversion systems.
What package is the ISO7761FDBQR available in and is it lead-free?
The ISO7761FDBQR is housed in a 16-pin SSOP package (JEDEC R-PDSO-G16, package equivalence SSOP16 at 0.25-inch pitch). It is RoHS compliant with a lead-free termination finish as confirmed by Pbfree Code Yes, meeting environmental requirements for global electronics markets.
