Detailed Description
The device is able to switch all kind of resistive, inductive and capacitive loads, limited by EAS and maximum
current capabilities.
The BTS3405G offers ESD protection of each IN Pin in relation to the corresponding Source Pin.
The overtemperature protection is in order to prevent the device from overheating due to overload and/or bad
cooling conditions. The temperature information is given by a temperature sensor in each of the two power
MOSFET. During thermal shutdown the device tries to sink an increased input current at the corresponding IN pin
to feedback the fault condition on this channel.
The BTS3405G has a thermal-auto-restart function, the regarding channel will turn on again after the measured
temperature has dropped for the thermal hysteresis.
The over voltage protection is active during load-dump or inductive turn off conditions. The power MOSFET is
turned on if the Drain-source voltage gets too high. This function is available without supply, means without voltage
on the IN pins.

Protection Functions
The device provides embedded protection functions. Integrated protection functions are designed to prevent IC
destruction under fault conditions described in the data sheet. Fault conditions are considered as “outside” normal
operation.
6.1
Thermal Protection
The device is protected against over temperature due to overload and / or bad cooling conditions. To ensure this
a temperature sensor located in the Power MOSFET is used.
The BTS3405G has a thermal auto-restart function. After the device has cooled down it will switch on again see

When switching off inductive loads with low-side switches, the Drain-Source voltage VD rises above battery
potential, because the inductance intends to continue driving the current.

Switching an Inductance
While demagnetization of inductive loads, energy has to be dissipated in the BTS3405G. This energy can be
calculated with following equation:

Short Circuit Protection
The condition short circuit is an overload condition of the device. If the current reaches the value of Ilim the device
starts to limit the current. In the condition of current limitation the device heats up. If the thermal shutdown
temperature is reached the device turns off. Figure 15 shows this behavior. During the current limitation the input
current is above IINnom. During the time period tdlim, the current can be above Ilim.

Short Circuit Behavior of BTS3405G
As the device is a low side switch it can be assumed that the Source to Ground path has a neglectable low
impedance and resistance. Therefore all impedance and resistance in the load path during short circuit is merged
into Zsc.
