Description

The BTS740S2 is designed as one kind of N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input, diagnostic feedback and proportional load current sense monolithically integrated in Smart SIPMOS technology that providing embedded protective functions.

BTS740S2 can be used in all types of resistive, inductive and capacitve loads; most suitable for loads with high inrush currents, so as lamps; replaces electromech-anical relays, fuses and discrete circuits and µC compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads. And the basic functions of BTS740S2 are:(1)cmos compatible input; (2)undervoltage and overvoltage shutdown with auto-restart and hysteresis; (3)fast demagnetization of inductive loads; (4)logic ground independent from load ground.

The absolute maximum ratings of the BTS740S2 can be summarized as:(1)supply voltage:43 V;(2)supply voltage for full short circuit protection:34 V;(3)load current:self-limited A;(4)operating temperature range:-40 to +150°C;(5)storage temperature range:-55 to +150°C;(6)power dissipation (DC) Ta=25°C:3.8 W;(7)input voltage (DC):-10 to +16 V.
