FEATURES
● 2 channel topology: low side input with common ground● Wide range input DC voltage: – VI = - 0.3 to 30 V with RI = 0 Ω – VI = - 30 to 35 V with RI = 750 Ω
● Current limiter: – 3 to 7.5 mA programmable reference – ILIM = 6.1 mA to 8.8 mA with RREF = 10 kΩ – ILIM = 2.8 mA to 4.3 mA with RREF = 22 kΩ – Narrow limiter spread: < 17% – Temperature compensated operation
● Output drive: – No output activation below 2 mA input – 1.5 mA minimum output activating current in opto-coupler mode – Programmable CMOS output mode option (VMOD > 2.9 V)
● LED drive for sensor status: 4.4 mA typical with RREF = 10 kΩ
● Input protection (RI = 750 Ω CIN = 22 nF)
● IEC 61000-4-2 ESD, Level 4 – In contact, ± 8 kV; in air, ± 15 kV – Criteria B: temporary disruption
● IEC 61000-4-5 voltage surge, Level 3 – ± 500 V with 42 Ω series resistor in differential mode – Criteria B: temporary disruption
● IEC 61000-4-4 transient burst immunity – ± 4 kV peak voltage; 5 kHz repetitive rate – Criteria A: fully f...
