Overview
The BTS 5235G is a dual channel high-side power switch (two times 60 mΩ) in
P-DSO-20-21 package providing embedded protective functions.
The Enhanced IntelliSense pins IS1 and IS2 provide a sophisticated diagnostic feedback
signal including current sense function, over load and over temperature alerts in ON-
state and open load alert 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.
