Overview
The TPT29336 device is a dual bidirectional I3C, SMBus, and I3C voltage-level translator with an enable (EN) input, and work from 1.2V to 3.6V VREF1 and 1.8V to 5.5V VREF2.
The 3.5Ω Ron make the minimal propagation delay <1.5ns. If EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, will allow bidirectional data flow between ports. If EN is low, the translator switch is off, and a high-impedance state exists between ports to isolate both sides.
The TPT29336 can also be used to run two buses, one is 400 kHz and the other is 100 kHz. If the two buses are operating at different frequency, the 100 kHz bus must be isolated when the other 400 kHz bus is required. If the master is running at 400 kHz, the maximum system frequency may be less than 400 kHz because of the delays added by the translator.
As with the standard I3C-bus and I3C compatible system, pull-up resistors are required in both sides, to provide the logic HIGH levels on the translator’s bus. The device is designed to work with SM, FM and FM+ I3C-bus devices in addition to SMBus devices. The maximum frequency is dependent on the RC time constant, and supports 12.5 MHz.
TPT29336 is available in MSOP8 and VSSOP8 package, and is characterized from –40°C to +125°C.
