TPT29617A
TPT29617A is Dual Channel Bidirectional I2C Bus Level Shift and Repeater manufactured by 3PEAK.
Features
Description
- Dual channel level shift and repeater for SDA/SCL Lines in I2C Applications and SMBus patible
- Support multi-mode: Standard-mode (SM), Fastmode (FM), and Fast-mode Plus (FM+)
- Open-Drain I2C Input/Output
- Latching free operation
- Allows Voltage-Level Translation Between
- VREF1 range 0.8 V to 5.5 V
- VREF2 range 2.2 V to 5.5 V
- 5 V tolerant I2C-bus and enable pins
- High-impedance SCL1, SDA1, SCL2 and SDA2 pins for EN = LOW
- Support Low level output current up to 30 m A
- Latch-Up performance exceeds 600 m A
- ESD Protection:
- 7000-V Human-Body Model
- 1500-V Charged-Device Model
The TPT29617A device is a dual channel I2C level shift and repeater function with an enable (EN) input, and work from 0.8 V to 5.5 V VREF1 and 2.2 V to 5.5 V VREF2.
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.
Dual channel, bidirectional buffer isolates capacitance and allows 540 p F on either side of the device at 1 MHz and up to 4000 p F at lower speeds.
TPT29617A is available in SOP8 and MSOP8 package, and is characterized from
- 40°C to +125°C.
Applications
- I2C, SMBus, PMBus, MDIO, UART, Low-Speed SDIO, GPIO, and Other Two-Signal Interfaces
- Servers/Storages
- Routers (Tele Switching Equipment)
- Personal puters/Consumer handsets
- Industrial Automation
