Product Brief
BTS 5236-2GS
Smart High-Side Power Switch
Two Channels 50 mΩ
T H E B T S 5 2 3 6 - 2 G S is a dual channel high-side power switch
(50 mΩ per channel) 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, 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.
