ISOW7741-Q1 Automotive Quad-Channel 3/1 Reinforced Digital Isolator
Texas Instruments' isolator features an integrated low-emission, low-noise DC/DC converter
Texas Instruments' ISOW7741-Q1 is a galvanically-isolated quad-channel digital isolator with an integrated high-efficiency power converter with low emissions. The integrated DC/DC converter provides up to 550 mW of isolated power, eliminating the need for a separate isolated power supply in space-constrained isolated designs.
Features

- Ambient temperature range Grade 1: -40°C to +125°C
- Data rate: 100 Mbps
- Integrated DC/DC converter with low emissions and low noise:
- Emission-optimized to meet CISPR25
- Low-frequency power converter: 25 MHz enables low-noise performance
- Low output ripple: 24 mV
- High-efficiency output power:
- Efficiency at max. load: 46%
- Output power: up to 0.55 W
- VISOOUT accuracy: 5%
- 5 V to 5 V available load current: 110 mA (max.)
- 5 V to 3.3 V available load current: 140 mA (max.)
- 3.3 V to 3.3 V available load current: 60 mA (max.)
- Independent power supply for a channel isolator and power converter:
- Logic supply range (VIO): 1.71 V to 5.5 V
- Power converter supply range (VDD): 3 V to 5.5 V
- Robust electromagnetic compatibility (EMC):
- System-level ESD, EFT, and surge immunity
- IEC 61000-4-2 contact discharge protection: ±8 kV across the isolation barrier
- Reinforced and basic isolation options
- High CMTI: 100 kV/µs (typ.)
- Safety-related certifications:
- VDE reinforced and basic insulation per DIN EN IEC 60747-17 (VDE 0884-17)
- UL 1577 component recognition program
- IEC 62368-1, IEC 61010-1, IEC 60601-1, and GB 4943.1-2011
- ISOW774xB devices are planned
- Extended temperature range: -40°C to +125°C
- Package: 20-pin wide-body SOIC
Applications
- Hybrid, electric, and powertrain systems (EV/HEV):
- Battery management systems (BMS)
- Onboard chargers (OBC)
- Traction inverters
- DC/DC converters
