6.1.1
Unsupplied
In this state, the device is either unsupplied (no voltage applied to VS pin) or the supply voltage is below the
undervoltage threshold.
6.1.2
Power-up
The Power-up condition is entered when the supply voltage (VS) is applied to the device. The supply is rising
until it is above the undervoltage threshold VS(OP) therefore the internal Power-On signals are set.
6.1.3
Sleep mode
The device is in Sleep mode when all Digital Input pins (IN, DEN) are set to “low”. When BTS7040-1EPA is in
Sleep mode, the output is OFF. The current consumption is minimum (see parameter IVS(SLEEP)). No
Overtemperature or Overload protection mechanism is active when the device is in Sleep mode. The device
can go in Sleep mode only if the protection is not active (counter = 0, see Chapter 8.3.1 for further details).
6.1.4
Stand-by mode
The device is in Stand-by mode as long as DEN pin is set to “high” while input pin is set to “low”. All channels
are OFF therefore only Open Load in OFF diagnosis is possible. Depending on the load condition, either a fault
current IIS(FAULT) or an Open Load in OFF current IIS(OLOFF) may be present at IS pin. In such situation, the current
consumption of the device is increased.
6.1.5
Active mode
Active mode is the normal operation mode of BTS7040-1EPA. The device enters Active mode as soon as IN pin
is set to “high”. Device current consumption is specified with IGND(ACTIVE) (measured at GND pin because the
current at VS pin includes the load current). Overload, Overtemperature and Overvoltage protections are
active. Diagnosis is available.
