PCA9615
2-channel multipoint Fast-mode Plus differential I²C-bus buffer with hot-swap logic.
(Sıcak takas mantığına sahip 2 kanallı çok noktalı 'Hızlı Mod'da diferansiyel I²C Lojik Buffer)
Features and benefits
• New dI2C-bus buffers offer improved resistance to system noise and ground offset up to 1⁄2 of supply voltage
• 2 channel dI2C (differential I2C-bus) to Fm+ single-ended buffer operating up to 1 MHz with 30 mA SDA/SCL drive capability
• Hot swap (allows insertion or removal of modules or card without disruption to bus data)
• EN signal (PCA9615 input) controls PCA9615 hot swap sequence
• Bus idle detect (PCA9615 internal function) waits for a bus idle condition before connection is made
• Compatible with I2C-bus Standard/Fast-mode and SMBus, Fast-mode Plus up to 1 MHz
• Single-ended I2C-bus on card side up to 540 pF
• Differential I2C-bus on cable side supporting multi-drop bus
– Maximum cable length: 3 m (approximately 10 feet) (longer at lower frequency)
– dI2C output: 1.5 V differential output with nominal terminals
– Differential line impedance (user defined): 100 Ω nominal suggested
– Receive input sensitivity: ±200 mV
– Hysteresis: ±30 mV typical
– Input impedance: high-impedance (200 kΩ typical)
– Receive input voltage range: -0.5 V to +5.5 V
• Lock-up free operation
• Supports arbitration and clock stretching across the dI2C-bus buffers
• Powered-off and powering-up high-impedance I2C-bus pins
• Operating supply voltage (VDD(A)) range of 2.3 V to 5.5 V with single-ended side 5.5 V tolerant
• Differential I2C-bus operating supply voltage (VDD(B)) range of 3.0 V to 5.5 V with 5.5 V tolerant. Best operation is at 5 V.
• ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
• Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
• Package offering: TSSOP10
Applications
• Monitor remote temperature/leak detectors in harsh environment
• Control of power supplies in high noise environment
• Transmission of I2C-bus between equipment cabinets
• Commercial lighting and industrial heating/cooling control
• Any application that requires long I2C-bus runs in electrically noisy environments
• Any application with multiple power suppliers and the potential for ground offsets up to 2.5 V
