TPT29306 Dual Bidirectional I2C Bus and SMBus Voltage-Level Translator Features ⚫ ⚫ ⚫ ⚫ Description Dual bidirectional Translator for SDA and SCL Lines The TPT29306 device is a dual bidirectional I2C and in I2C Applications and SMBus Compatible SMBus voltage-level translator with an enable (EN) input, Support multi-mode: Standard-mode (SM), Fast- and work from 1.2V to 3.6V VREF1 and 1.8V to 5.5V VREF2. mode (FM), and Fast-mode Plus (FM+) The 3.5Ω Ron make the minimal propagation delay <1.5ns. Less than 1.5 ns (max) Delay to Accommodate SM If EN is high, the translator switch is ON, and the SCL1 and FM I2C devices and multiple masters and SDA1 I/O are connected to the SCL2 and SDA2 I/O, Allows Voltage-Level Translation Between will allow bidirectional data flow between ports. If EN is ◼ 3.3V VREF1 and 5V VREF2 ◼ 2.5V VREF1 and 3.3V or 5 V VREF2 ◼ 1.8V VREF1 and 2.5V, 3.3V, or 5V VREF2 ◼ 1.2V VREF1 and 1.8V, 2.5V, 3.3V, or 5V VREF2 low, the translator switch is off, and a high-impedance state exists between ports to isolate both sides. The TPT29306 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 Provides bidirectional voltage translation with no isolated when the other 400 kHz bus is required. If the direction pin master is running at 400 kHz, the maximum system High-impedance SCL1, SDA1, SCL2 and SDA2 pins frequency may be less than 400 kHz because of the for EN = LOW delays added by the translator. Latch-Up performance exceeds 400 mA per JESD As with the standard I2C-bus system, pull-up resistors are 78 required in both sides, to provide the logic HIGH levels on ESD Protection Exceeds JESD 22 the translator’s bus. The device is designed to work with ◼ 4000-V Human-Body Model ◼ 1000-V Charged-Device Model SM, FM and FM+ I2C-bus devices in addition to SMBus devices. The maximum frequency is dependent on the RC time constant, but generally supports > 2 MHz. TPT29306 is available in MSOP8, DFN1.4X1-8L and DFN3X4-8L(none e-pad) package, and is characterized from –40°C to +85°C.
