DUAL 2-A LOW DROP OUT SWITCH MULTIWATT15

The UAF1780-1781-1782 are dual interface circuits delivering high output currents and capable of driving any type of load.
An on-chip dc/dc conversion unit in conjuction with a few low-cost external components (a low value inductor and a low voltage capacitor) are implemented to limit the saturation voltage thereby optimizing the efficiency.
The devices are particularly well protected against destructive overloads. Each output implements a current limit circuitry, a desaturation monitoring unit for the detection of overloads and short-circuits, and a thermal protection feature.
Corresponding output is tumed oft in case ot prolonged desaturation or excessive internal dissipation. This condition is reflected by a low level on ALARM output terminal. This protection unit can be reactivated by applying a logic low signal to RESET input.
However, tor inductive loads, a delay is imposed on signal applied to this RESET input so as to prevent a rapid and premature conduction of output transistors.
A logic high signal applied to STROBE input will disable both power outputs.
The devices operates within a supply voltage range of+8V to +32V.
• LOW POWER DISSIPATION (LOW Vsat: 1 0.6 V @ 2 A)
• ALL INPUTS ARE OPERATIONAL WITH CONTROL SIGNALS HIGHER THAN Vcc
• ALL INPUTS WITHSTAND VOLTAGES LOWER THAN GROUND
• HIGH OUTPUT CURRENTS PROTECTION OF OUTPUT TRANSISTORS (UP TO + 32 v)
• THE OUTPUTS CAN WITHSTAND VOLTAGES LOWER THAN GROUND
• WITHSTAND ON Vcc SPIKES UP TO (60 V, 10 ms)
• DIFFERENTIAL INPUTS

The devices are from old stock (OEM industrial , mainly from Germany), but they are NEW and UNUSED (NOS devices), taken out from the original packaging ( see photo).
What you see on the photo, is what you get.
Manufacturer is STM (Datasheet available on the Internet.)
