Both switches drive complex resistive, capacitive, and inductive loads with one side connected to ground, such as valves, relays, and lamps. They can be used in SIL-rated applications such as safety sensors, as well as general factory automation and process control equipment such as programmable logic controllers (PLCs), I/O peripherals, and computer numerical control (CNC) machines.
Built-in safeguards to protect the IC, the application and the load include ground-disconnect and VCC-disconnect protection, thermal shutdown, under-voltage lock-out and short-circuit cut-off. This last feature provides non-dissipative protection that minimises overheating. It acts after a delay and is programmed with an external capacitor.
The IPS160HF and IPS161HF are in production now and available in the thermally enhanced PowerSSO12 package.
