High/low-side power switch, 1 channel, 6 ... 48 V, SO-8

TDE1707BFP, INTELLIGENT POWER SWITCH

Description
The E-TDE1707BFP is a 0.5A Integrated Power Switch with up to 48V Power supply capability. Two output configurations are possible:
- Load to Gnd. (High Side Mode)
- Load to Vs (Low side Mode)
Especially dedicated to proximity detectors, its internal +5V supply can be used to supply external circuits. A signal is internally generated to block the In signal, and prevent activation of 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, concurr to the generation of such signal. A minimum delay of 25µs (Typ.value) is added to the trailing edge of such signal to ensure that a stable normal situation is present when the signal disappears. The delay (of the disapperance of the block signal; no delay at its on set) can be further increased connecting a capacitor between pin3 and ground. It can drive resistive or inductive loads
