Frequently Asked Questions
What makes the PTCA9511ADGKR suitable for hot-swap applications?
The PTCA9511ADGKR is specifically designed as a hot-swappable I2C and SMBus buffer, meaning it allows circuit boards to be inserted or removed from a live bus without causing bus lock-up or data corruption. It provides voltage isolation between segments during the transition, protecting all connected devices.
What interface protocol does the PTCA9511ADGKR support?
The PTCA9511ADGKR supports both I2C and SMBus protocols. SMBus is widely used in power management and system health monitoring applications in servers and embedded platforms, while I2C is a standard two-wire interface used across a wide range of sensors, EEPROMs, and peripheral devices.
What is the package type and pin count of the PTCA9511ADGKR?
The PTCA9511ADGKR is housed in an 8-pin TSSOP (Thin Shrink Small Outline Package) with 0.19-inch pitch, identified by JESD-30 code S-PDSO-G8. This small surface-mount package is suitable for high-density board designs and automated PCB assembly.
Is the PTCA9511ADGKR RoHS compliant?
Yes, the PTCA9511ADGKR is RoHS compliant as indicated by its JESD-609 code e4 and Pb-free designation. It is manufactured using plastic/epoxy materials without lead or other restricted substances, making it compliant with global environmental regulations for electronic components.
When was the PTCA9511ADGKR introduced and what systems is it designed for?
The PTCA9511ADGKR was introduced on October 21, 2019, and is designed for modern systems requiring robust I2C/SMBus bus management, particularly in server backplanes, telecommunications racks, and industrial controllers. Its hot-swap capability makes it especially valuable in high-availability systems requiring zero-downtime maintenance.
