5.1.5 Board Level Isolation and Protection

TI provides a range of isolation designs analog or digital with basic or reinforced isolation. The following links provide information on the products.

ISO224

The ISO224 is a precision isolated amplifier with an output separated from the input circuitry by an isolation barrier of up to 5 kVRMS with an exceptionally long lifetime and low power dissipation. The input of the ISO224 is optimized for accurate sensing of ±10V signals that are widely used in industrial applications. The device operates of a single supply on the high-side. This unique feature simplifies the design of the isolated power supply and reduces the system cost. The integrated high-side supply voltage detection feature simplifies system level diagnostics.

UCC12050

UCC12050 is a DC/DC converter with 5kVRMS reinforced isolation rating designed to provide efficient, isolated power to isolated circuits that require a bias supply with a well-regulated output voltages. The device integrates a transformer and DC/DC controller with a proprietary architecture to provide 500mW (typical) of isolated power with high efficiency and low EMI. The device also has an enable pin, synchronization capability, and regulated 5V or 3.3V output options with headroom. The UCC12050 is a low-profile, miniaturized solution offered in a wide-body SOIC package with 2.65mm height (typical).

AMC3301

The AMC3301 is a precision, isolated amplifier with a fully integrated, isolated DC/DC converter that allows single-supply operation from the low-side of the device. The input of the AMC3301 is optimized for direct connection to shunt resistors or low voltage-level signals. The integrated isolated DC/DC converter makes the device a unique solution for space-constrained applications.

ISO774x

The ISO774x devices are high-performance, quad-channel digital isolators with 5000VRMS (DW package) and 3000 VRMS (DBQ package) isolation ratings per UL 1577. The ISO774x devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. If the input power or signal is lost, default output is high for devices without suffix F and low for devices with suffix F.

ISOW64xx, ISOW3080, ISOW1050

The ISO-Watt Family of device (ISOW64xx, ISOW3080, ISOW1050) are signal isolators with Integrated DC-DC converteres into a single device. This saves the need of generate isolated power and makes the design and layout significantly easy and saved significant space and cost. Along with that this family of devices are designed to meet best EMC performance. ISOW64xx is a digital isolator with integrated power and ISOW3080 is isolated RS485 with integrated power and ISOW1050 is an isolated CAN with integrated power. These are reinforced isolation devices with VISO = 5000VRMS. This
