Product Brief
BTT6050-2EKA (Truck device) PROFET™+ 24V
Smart High-Side Power Switch for 2xP21W Lighting Load
Basic Functions
The BTT6050-2EKA is the first device of the new PROFET™+ 24V family. It is a dual
channel High-Side Power Switch (two times 50mΩ) in DSO-14 EP Package providing
„„
RoHS compliant & AEC qualified
excellent diagnostics and protection features.
„„
Op. Voltage range (5.0 … 36.0V)
„„
Low stand-by current (< 0.5μA)
The device is specifically designed to drive light bulbs and LEDs in harsh automotive
„„
ESD protection, optimized EMC
environments, for example, on trucks, farming machines or any other kind of 24V
„„
PWM capability up to 200Hz
supply voltage applications.
„„
3.3V and 5V–compatible
logic inputs
Its benchmark short circuit robustness (min. 100k cycles) extends system lifetime
and its high current sense accuracy enables it to diagnose the smallest loads such as
„„
Improved heat dissipation of
DSO package
LEDs.
Protection Functions
„„
Load Dump: 65V
Applications
„„
Target load: 2xP21W lighting load
