ADG5462F

Data Sheet User Defined Fault Protection and Detection,10 Ω RON, Quad Channel Protector ADG5462F FEATURES User defined secondary supplies set overvoltage level Overvoltage protection up to −55 V and +55 V Power-off protection up to −55 V and +55 V Overvoltage detection on source pins Minimum secondary supply level: 4.5 V single-supply Interrupt flag indicates fault status Low on resistance: 10 Ω typical On-resistance flatness: 0.5 Ω maximum 4 kV human body model (HBM) ESD rating Latch-up immune under any circumstance VSS to VDD analog signal range ±5 V to ±22 V dual supply operation 8 V to 44 V single-supply operation Fully specified at ±15 V, ±20 V, +12 V, and +36 V APPLICATIONS Analog input/output modules Process control/distributed control systems Data acquisition Instrumentation Avionics Automatic test equipment Communication systems GENERAL DESCRIPTION The ADG5462F contains four channels that are overvoltage protected. The channel protector is placed in series with the signal path and protects sensitive components from overvoltage faults in that path. The channel protector prevents overvoltages when powered and unpowered, and it is ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply voltages define the on-resistance profile, while the secondary supply voltages define the voltage level at which the overvoltage protection engages. When no power supplies are present, the channel remains in the off condition, ...
