STMicroelectronics IPS160H/IPS161H Monolithic High-Side Switches
These single high-side switches help ensure safety of automation systems
The IPS160H and IPS161H from STMicroelectronics are monolithic high-side switches which can drive capacitive, resistive or inductive loads with one side connected to ground. The high-side switches are intended for use in designs which must comply with the requirements of the Safety Integrity Level (SIL) specifications applied by functional safety standards.
Features of the STMicroelectronics IPS160H and IPS161H that support functional-safety compliance include extended diagnostics and embedded protection functions. Engineers developing safety applications aimed at the highest SIL grades will also benefit from an operating-voltage range up to 60V, and on-resistance of 60mΩ. Also useful in these applications are extended diagnostic functions for detecting open load, overload and over-temperature conditions.
To minimise power dissipation when the output is shorted, the ST IPS16xH switches implement a non-dissipative short-circuit cut-off protection function: it limits the average output current, and this protects the device against overheating.
A common diagnostic pin reports thermal shut-down, open-load in the Off state, and cut-off events. The cut-off delay time may be programmed with an external capacitor.
