1 Amp limited 8 channel switch senses overload, cuts-off and restart automatically

Industrial electronics engineers dread short-circuits and any such current overload issues. The new over-current protection featured 8 line switch in a monolithic package from STMicroelectronics can handle current up to 1 Amp in each bus-line. They are made to suit well for industrial control applications such as PLCs to drive below 1-Amp-range current loads such as motors and many such control units. These devices feature protection against over load and junction temperature on every line. The new IPS8160HQ and IPS8160HQ-1 high-side octal switches takes less space by having packaged in compact QFN48L.
STMicro said IPS8160HQ and IPS8160HQ-1enhance reliability in PLC modules used for driving heavy loads and unidirectional motors in vending machines. Suggested applications include I/O peripherals in factory automation equipment, computer numerical control (CNC) machines, and in general for controlling resistive, capacitive, and inductive loads with one side connected to ground. Both switches have low on-resistance (RDS(on)) of 160mOhm (typ.at Deg 25C), which helps minimize power dissipation. Once overload is detected these switches turn off immediately but later restart automatically, whereas other non-overloaded channels continue to operate normally. These device turns off i...
