5 A integrated power switches with up to 48 V power supply capability.
Two output configurations are possible.
The former is the load to GND (high-side mode) and the latter is the load to VS (low-side mode).
This device is dedicated to proximity detectors; its internal +5 V supply can be used to supply external circuits (please refer to AN495 and AN1213 on www.
st.
com).
A signal is internally generated to block the IN signal, and prevent the output switch, as long as an abnormal condition is detected.
The power-on transition, as well as the chip overtemperature and the output overcurrent, generate this signal.
A minimum delay of 25 μs (typ.
value) is added to the trailing edge of this signal to ensure that a stable normal situation is present when the signal disappears.
The delay (the disappearance of block signal) can be further increased by connecting a capacitor between pin 3 and ground.
It can drive resistive or inductive loads.
