Product Overview
PCA9616PW,118 is a 3-channel multipoint fast-mode plus differential I²C-bus buffer with hot-swap logic in a 16 pin TSSOP package. The PCA9616 is a Fast-mode Plus (Fm+) SMBus/I²C-bus buffer that extends the normal single-ended SMBus/I²C-bus through electrically noisy environments using a differential SMBus/I²C-bus physical layer, which is transparent to the SMBus/I²C-bus protocol layer. It consists of three single-ended to differential driver channels for the SCL, SDA and a third channel useful for INT or other signalling. Typical applications include any application with multiple power supplies and the potential for ground offsets up to 2.5V, any application that requires long I²C-bus runs in electrically noisy environments, monitor remote temperature/leak detectors in harsh environment with interrupt back to host, control of power supplies in high noise environment, transmission of I²C-bus between equipment cabinets and commercial lighting and industrial heating/cooling control.
- I²C buffers offer improved resistance to system noise and ground offset up to 1⁄ 2 of supply voltage
- Hot swap (allows insertion or removal of modules or card without disruption to bus data)
- Active low READY signal (PCA9616 output) indicates device is ready from a cold start
- EN signal (PCA9616 input) controls PCA9616 hot swap sequence
- Bus idle detect (PCA9616 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 1MHz
- Active HIGH (internal pull-up resistor) enable disables the device to high-impedance state
- Single-ended I²C-bus on card side up to 540pF
2.2V and 400pF - Differential I²C-bus on cable side supporting multi-drop bus
- Lock-up free operation, supports arbitration and clock stretching across the I²C-bus buffers
