Product Overview
ISO808AQTR is a galvanic isolated octal high-side power solid state relay with an SPI interface for high inductive loads. Each driver contains 2 independent galvanic isolated voltage domains. The IC is intended for driving any kind of load with one side connected to the ground. The control logic stage features an 8bit output status register (where the MCU sets the ON/OFF status of the output channels in the process stage), and daisy chaining is allowed. The two stages communicate through the galvanic isolation channel by an ST proprietary protocol. Other embedded functions are loss of ground protection, VCC and VDD UVLOs (with hysteresis), watchdog and VCC Power GOOD. Typical applications are programmable logic control, industrial PC peripheral input/output, numerical control machines, and drivers for all type of loads (resistive, capacitive, inductive).
- Fast demagnetization of inductive loads VDEMAG(TYP) = VCC - 54V
- Low process and logic sides supply current, loss of GND and VCC protections
- Under-voltage shut down with auto restart and hysteresis
- Logic side 5V and 3.3V TTL/CMOS and MCU compatible I/Os
- Logic side SPI interface, common output enable/disable pin
- Reset function for IC outputs disable, high common mode transient immunity
- Per-channel over-temperature protection with thermal independence of separate channels
- Case over-temperature protection, over-voltage protection (VCC clamping)
- Meets IEC 61000-4-2, IEC 61000- 4-4, IEC 61000-4-5 and IEC 61000-4-8, UL1577 and UL508 certified
- TFQFPN32 package, -40 to 150°C storage temperature
