Product Brief
BTS 5231-2GS
Smart High-Side Power Switch
Two Channels 140 mΩ
T H E B T S 5 2 3 1 - 2 G S is a dual channel high-side power switch (two
times 140 mΩ) in PG-DSO-14 package providing embedded protective functions.
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.
