Description

The BTS737S3 feayures are as follows:
• N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input and diagnostic feedback, monolithically integrated in Smart SIPMOS^®technology.
• Providing embedded protective functions

The BTS737S3 is a N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input and diagnostic feedback, monolithically integrated in Smart SIPMOS technology.It is designed for (1)C compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads; (2)all types of resistive and capacitve loads; (3)most suitable for loads with high inrush currents, so as lamps; (4)replaces electromechanical relays, fuses and discrete circuits.

Features of the BTS737S3 are:(1)short circuit protection; (2)overload protection; (3)current limitation; (4)thermal shutdown; (5)reverse battery protection with external resistor; (6)overvoltage protection with external resistor (incl. load dump); (7)loss of ground protection; (8)electrostatic discharge protection (ESD).For further information on technology, delivery terms and conditions and prices please contact your nearest Infineon Technologies Office in Germany or our Infineon Technologies Representatives worldwide (see address list).Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as "outside" normal operating range. Protection functions are not designed for continuous repetitive operation.

The absolute maximum ratings of the BTS737S3 can be summarized as:(1)supply voltage:40V;(2)storage temperature range:-55 to 150;(3)operating temperature range:-40 to 150;(4)power dissipation:3.7W;(6)supply voltage for full short circuit protection:36V.Infineon Technologies Components may only be used in life-support devices or systems with the express written approval of Infineon Technologies, if a failure of such components can reasonably be expected to cause the failure of that life-support device or system, or to affect the safety or effectiveness of that device or system. Life support devices or systems are intended to be implanted in the human body,or to support and/or maintain and sustain and/or protect human life. If they fail, it is reasonable to assume that the health of the user or other persons may be endangered.
