ISO808TR-1

ISO808TR-1 is a galvanic isolated octal high-side power solid state relay for high inductive loads. It is an 8-channel driver featuring a low supply current. It contains 2 independent galvanic isolated voltage domains (VCC and VDD for the process and control logic stages). The IC is intended for driving any kind of load with one side connected to the ground. Active channel current limitation (OVL) combined with thermal shutdown (OVT), independent of each channel, protects the device against overload. Built-in thermal shutdown protects each channel from overtemperature and overload: each overheated channel automatically turns OFF after its junction temperature triggers the protection threshold. Other embedded functions are loss of ground protection, VCC and VDD UVLOs (with hysteresis), and watchdog. Typical applications are programmable logic control, industrial PC peripheral input/output, numerical control machines, drivers for all type of loads (resistive, capacitive, inductive).

• VCC(AMR) = 45V, wide process side operating range VCC = 9.2 to 36V
• RDS(on) = 0.125ohm per channel (typical)
• Fast demagnetization of inductive loads VDEMAG(TYP) = VCC to 54V
• Low process and logic sides supply current, common output enable/disable pin
• Under-voltage shut down with auto-restart and hysteresis, case over-temperature protection
• Logic side 5V and 3.3V TTL/CMOS and MCU compatible I/Os, common fault open drain diagnostic
• Reset function for IC outputs disable, high common mode transient immunity
• Per-channel over-temperature protection with thermal independence of separate channels
• Meets IEC 61000-4-2, IEC 61000- 4-4, IEC 61000-4-5 and IEC 61000-4-8, UL1577 and UL508 certified
• PowerSO-36 package
