The BTS 5241L is a dual channel high-side power switch (two times 25 mΩ) in
P-DSO-12-2 power package providing embedded protective functions including
ReverSave.
ReverSave is a protection feature that causes the power transistors to switch on in case
of reverse polarity. As a result, the power dissipation is reduced to almost forward
condition.
The Enhanced IntelliSense pins IS1 and IS2 provide a sophisticated diagnostic feedback
signal including current sense function and open load in off state. The diagnosis signals
can be switched on and off by the sense enable pin SEN.
An integrated ground resistor as well as integrated resistors at each input pin (IN1, IN2,
SEN) reduce external components to a minimum.
The power transistor is built by a N-channel vertical power MOSFET with charge pump.
The inputs are ground referenced CMOS compatible. The device is monolithically
integrated in Smart SIPMOS technology.
