ISO1640BDR Typical application Circuitry

ISO1640BDR is a high-performance, six-channel digital isolator chip designed by Texas Instruments. The primary function of the chip is to transfer digital signals between sections of a system while maintaining a high degree of electrical isolation between those sections.

This chip is commonly employed in scenarios that require isolation, such as industrial automation systems, isolated SPI, I2C interfaces, isolated ADCs and DACs, and medical applications.

The ISO1640BDR stands out due to the following key features:

1. Six Channel: The ISO1640BDR provides six isolated channels with a channel configuration of 4/2.

2. Data Rate: Up to 100 Mbps of data rate are supported by the chip.

3. Robust Isolation: It offers a maximum isolation rating of 5 kVRMS.

4. Wide Supply Range: The ISO1640BDR operates from a 2.25 V to 5.5 V supply range, offering compatibility with a wide range of devices.

5. Low Power Consumption: It is designed for low power consumption, only using 1.6 mA per channel at 1 Mbps.

Now, let's describe an application where we are using ISO1640BDR for isolating a microcontroller's SPI bus:

1. Power Supply: Pin VCC1 (pin 3) and GND1 (pin 5) are to be connected to the primary power source. The secondary side power source is to be connected to VCC2 (pin 16) and GND2 (pin 14).

2. SPI Lines: The microcontroller's SPI lines MOSI, MISO, and SCLK are connected to the inputs IN1, IN2, and IN3 (pins 1, 2, and 6, respectively) on the primary side. The corresponding isolated lines are connected to the outputs OUT4, OUT5, and OUT6 (pins 13, 12, and 11, respectively) on the secondary side.

3. Chip Select: The chip select line can be connected to IN4 (pin 7), and the corresponding isolated line is OUT1 (pin 10).

4. Decoupling Capacitors: Attach decoupling capacitors close to the VCC and GND pins to reduce noise.

When designing a circuit with ISO1640BDR, some considerations should be kept in mind:

- Isolated Power Supply: The isolated side (VCC2 and GND2) typically requires a separate power supply, which can be provided by an isolated DC-DC converter.

- Routing and Grounding: Proper routing and grounding practices must be adhered to, especially considering high-speed signals.

- Thermal Management: Since the device operates in a wide temperature range, adequate measures should be taken to keep the device within its safe operating temperature.

- Compatibility: The ISO1640BDR has a wide power supply range, but it's crucial to ensure it's compatible with other components in the circuit.

In conclusion, the ISO1640BDR is a versatile solution for applications requiring multiple channels of robust, high-speed digital isolation.
