The device provides integrated protection functions. These functions are designed to prevent the destruction of
the IC from fault conditions described in the data sheet. Fault conditions are considered as “outside” normal
operating range. Protection functions are designed for neither continuous nor repetitive operation.
6.1
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
pin.
In case of loss of device ground, it’s recommended to use input resistors between the microcontroller and the
BTS5012-1EKB to ensure switching OFF of channel.
In case of loss of module or device ground, a current (
