The BTF6070-2ERV is a 60 mΩ dual channel Smart High-Side Power Switch
It is specially designed to drive Valve Applications in the harsh automotive
environment.The µC compatible power switch can serve a wide application
portfolio starting from 12V, 24V and up to 42V DC.

In case of loss of the module ground and the load remains connected to ground,
the device protects itself by automatically turning OFF (when it was previously
ON) or remains OFF, regardless of the voltage applied on IN pins.

In case of loss of device ground, it’s recommended to use input resistors between
the microcontroller and the BTF6070-2ERV to ensure switching OFF of channels.

ZGND is recommended to be a resistor in series to a diode.
