The BTS 5434G is a four channel high-side power switch (four times 60 mΩ) in
P-DSO-28-19 package providing embedded protective functions.
The Enhanced IntelliSense pins IS1 to IS4 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 pins SENA and SENB.
Integrated ground resistors as well as integrated resistors at each input pin (IN1, IN2,
IN3, IN4, 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 built by two dual
channel chips, monolithically integrated in Smart SIPMOS technology.
