Figure 16 Timing of Diagnosis Signal in OFF-state

For open load diagnosis in off-state an external output pull-up resistor (R_OL) is necessary, because the integrated

pull-down current I_L(PD)causes secure suppression of the open load condition as long as no pull-up resistor is

activated. For calculation of the pull-up resistor, the pull-down current I_L(PD)and the open load threshold voltage

_OUT(OL)has to be taken into account.

_bb(min)– V_OUT(OL,max)

R_OL= ---------------------------------------------------------

_L(PD,max)+ I_leakage

_leakagedefines the leakage current in the complete system e.g. caused by humidity. V_bb(min)is the minimum supply

voltage at which the open load diagnosis in off-state must be ensured.

To reduce the stand-by current of the system, an open load resistor switch (S_OL) is recommended.

4.3.3

Sense Enable Function

The diagnosis signals can be switched off by a low signal at sense enable pin (SEN). See Figure 17 for details on

the timing between SEN pin and diagnosis signal I_IS. Please note that the diagnosis is enabled, when no signal is

provided at pin SEN.

Figure 17 Timing of Sense Enable Signal

The SEN pin circuit is designed equal to the input pin. Please refer to Figure 5 for details. The resistors R_limare

recommended to limit the current through the sense pins IS1 and IS2 in case of reverse polarity and overvoltage.

The stand-by current of the BTS5241-2L is minimized, when both input pins (IN1 and IN2) and the sense enable

pin (SEN) are on low level or left open and V_OUT< V_OUT(OL). In case of open load in off-state (V_OUT> V_OUT(OL)and

V_IN= 0 V), diagnosis tries to switch on automatically which causes an increase in supply current. To reduce the

stand-by current to a minimum, the open load condition has to be suppressed by opening S_OL.
