Texas Instruments I2C LED Driver: TCA6507
Texas Instruments' TCA6507 is the industry’s first I2C LED driver that can perform automatic gradual LED fading and control the brightness and blinking pattern, all at the same time using pulse-width modulation intensity control. The device features an internal self-contained oscillator that controls two PWM modules and provides two independent blink/fade patterns. The driver has very low power consumption of 25uA in operating mode and 10uA in standby, as well as superior drive capability. Applications include consumer, server, computing, and industrial markets, as well as applications in the handset market.
Texas Instruments Fault-Protected Transceiver
TI's SN65HVD1781 fault-protected, half-duplex, 1Mbps, RS-485 compatible transceiver is designed to survive over-voltage faults operating over the full 3.3V to 5V range. The bus pins can be shorted indefinitely to line voltages of up to +/-70V with no damage. The internal current-limit circuits allow fault survivability, without causing the high bus currents that otherwise might damage external components or power supplies. The transceiver is ideal for applications where there is a chance of damaging equipment by shorts to thepower rail and where reliability, survivability, and noise tolerance is essential.
Texas Instruments ISO7220 Dual Digital Isolators
Texas Instruments’ dual-channel digital isolators feature 1, 25, and 150-Mbps signaling rate options and operate with 3.3V or 5V supplies. A logic input and output buffer are separated by TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to 4000V. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and prevent noise currents on data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
