The BTF6070-2ERV is a 60mΩ dual channel Smart High-Side Power Switch, embedded in
a PG-TDSO-14, Exposed Pad package, providing protective functions and diagnosis.
The power transistor is built by a N-channel vertical power MOSFET with charge pump.
The device is integrated in Smart6 HV technology. It is specially designed to drive Valve
Applications in the harsh automotive environment. For lighting applications the nominal
bulb load of P10W+P5W 24V or P10W 12V is considered.

The BTS3050EJ is a 50 mΩ single channel Smart Low-Side Power Switch with in a
PG-TDSO8-31 package providing embedded protective functions. The power transistor
is built by an N-channel vertical power MOSFET. The device is monolithically integrated.
The BTS305EJ is automotive qualified and is optimizedfor 12 V automotive applications.
