ISL41387IRZ - Renesas Electronics

Description: These devices are BiCMOS interface ICs that are user configured as either a single RS-422, RS-485 differential transceiver, or as a dual (2 Tx, 2 Rx) RS-232 transceiver. In RS-232 mode, the on-board charge pump generates RS-232 compliant ±5V Tx output levels, from a supply as low as 4.5V. Four small 0.1µF capacitors are required for the charge pump. The transceivers are RS-232 compliant, with the Rx inputs handling up to ±25V, and the Tx outputs handling ±12V. In RS-485 mode, the transceivers support both t

ISL41387IRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use short, wide traces for power and ground connections.
  • Use a reliable communication protocol such as SPI or I2C, and ensure that the clock frequency is within the recommended range. Also, use a pull-up resistor on the SCL line and a pull-down resistor on the SDA line.
  • The ISL41387IRZ can handle a maximum current of 1.5A per channel. However, it's recommended to derate the current to 1.2A per channel for reliable operation.
  • Use a voltage regulator to regulate the input voltage to the recommended range. Add overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the device.
  • The recommended operating temperature range for the ISL41387IRZ is -40°C to 85°C. However, the device can operate up to 105°C with reduced performance.
