TCA9517DGKRQ1

The TCA9517DGKRQ1 is an automotive-qualified, dual bidirectional I²C bus and SMBus buffer with level shifting capabilities. This device is designed to support data transfer between I²C bus systems running at different voltage levels and to extend the I²C bus length.

Key Features:

• Voltage Level Translation: Supports voltage level translation between 1.2V to 5.5V on the A-side and 2.2V to 5.5V on the B-side
• Bus Capacitance: Can drive up to 400 pF on the B-side and 400 pF on the A-side
• I²C Bus Speed: Supports standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz)
• Bidirectional Communication: Allows bidirectional data flow between two I²C buses
• Offset Voltage: ±100 mV typical offset voltage on the B-side to prevent latch-up issues
• Low Standby Current: Low quiescent current for power-sensitive applications
• ESD Protection: High-level ESD protection
• Operating Temperature Range: -40°C to +125°C
• Package: 8-pin VSSOP (DGK) package
• Automotive Grade: AEC-Q100 qualified for automotive applications
• RoHS Compliant

Applications:

• Automotive infotainment systems
• Automotive body electronics
• Battery management systems (BMS)
• Industrial control systems
• Communication equipment
• Consumer electronics requiring I²C level shifting and bus extension
