17 / 46 page Data Sheet 17 Rev. 1.0 2018-05-14 PROFET™+ 24 V BTT6200-1ENA Protection Functions 6 Protection Functions 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 Loss of Ground Protection 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 BTT6200-1ENA to ensure switching OFF the channel. In case of loss of module or device ground, a current (IOUT(GND)) can flow out of the DMOS as illustrated in Figure 14. ZGND is recommended to be a resistor in series to a diode . Figure 14 Loss of Ground Protection with External Components 6.2 Undervoltage Protection Between VS(UV) and VS(OP), the undervoltage mechanism is triggered. VS(OP) represents the minimum voltage where the switching ON and OFF can takes place. VS(UV) represents the minimum voltage the switch can hold ON. If the supply voltage is below the undervoltage mechanism VS(UV), the device is OFF (turns OFF). As soon as the supply voltage is above the undervoltage mechanism VS(OP), then the device can be switched ON. When the switch is ON, protection functions are operational. Nevertheless, the diagnosis is not guaranteed until VS is in the VNOM range. Figure 15 sketches the undervoltage mechanism.
