ReverSaveTM is a protection feature that causes the power transistors to switch on in case of reverse polarity. As a result, the power dissipation is reduced. The BTS 6142D has a current controlled input and offers a diagnostic feedback with load current sense. The design is based on Smart SIPMOS chip on chip technology. 1.1 Block Diagram logic IC Rbb base chip Vbb voltage sensor IIN VIS VIN IS ESD IN driver logic I IS gate control & charge pump T clamp for inductive load current limitation load current sense forward voltage drop detection RIS OUT IL LOAD over temperature Overview .emf Figure 1 Data Sheet Block Diagram 5 V1.1, 2007-02-28 Smart High-Side Power Switch BTS 6142D Overview 1.2 Terms Following figure shows all terms used in this data sheet.

A series resistor RIN in the input path is also required for reverse operation at Vbb≤-16V. See also Figure 14. 4) Current limitation is a protection feature. Operation in current limitation is considered as “outside” normal operating range. Protection features are not designed for continuous repetitive operation.

Therefore the forward voltage drop VON at small load currents is no more proportional to the load current IL , but is controlled by an internal “two level controller” to remain clamped to a defined value VON(NL). Figure 7 shows the dependency for a typical device.

PCB is vertical without blown air. 3) Not subject to production test, parameters are calculated from RDS(ON) and Rth 4) Permanent Inverse operation results eventually in a current flow via the intrinsic diode of the power DMOS. In this case the device switches on with a time delay td(inv) after the transition from inverse to forward mode. A sense current IIS(fault) can be provided by the pin IS until standard forward operation is reached. Note: Characteristics show the deviation of parameter at the given supply voltage and junction temperature. Typical values show the typical parameters expected from manufacturing. Data Sheet 16 V1.1, 2007-02-28 Smart High-Side Power Switch BTS 6142D Protection Functions 4.2 Protection Functions The device provides embedded protective 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 operating range. Protection functions are neither designed for continuous nor repetitive operation. 4.2.1 Over-Load Protection The load current IL is limited by the device itself in case of over-load or short circuit to ground. There are multiple steps of current limitation ILx(SC) which are selected automatically depending on the voltage drop VON across the power DMOS. Please note that the voltage at the OUT pin is Vbb - VON. Figure 11 shows the dependency for a typical device. , /6& Tj = 25°C $ W\S 9 216& Figure 11 9 9 21 Typical Current Limitation Depending on the severity of the short condition as well as on the battery voltage the resulting voltage drop across the device varies. Whenever the resulting voltage drop VON exceeds the short circuit detection threshold VON(SC), the device will switch off immediately and latch until being reset via the input. The VON(SC) detection functionality is activated, when VbIN>10V typ. and the blanking time td(SC1) expired after switch on. In the event that either the short circuit detection via VON(SC) is not activated or that the on chip temperature sensor senses over-temperature before the blanking time td(SC1) expired, the device switches off resulting from over-temperature detection. After cooling down with thermal hysteresis, the devices switches on again. Please refer to Figure 12 for details.

During switch-on no current is provided, until the forward voltage drops below VON<1V typ. The output sense current is limited to IIS,lim. The pin IS provides in case of any fault conditions a defined fault current IIS(fault). Fault conditions are over-current (VON>1V typ.), current limit or over-temperature switch off. The pin IS provides no current during open load in ON, de-energisation of inductive loads and inverse current mode.

The accuracy of the provided current sense ratio (kILIS = IL / IIS) depends on the load current. Please refer to Figure 18 for details. A typical resistor RIS of 1 kΩ is recommended.

Note: During operation at low load current and at activated forward voltage drop limitation the “two level control” of VON(NL) can cause a sense current ripple synchronous to the “two level control” of VON(NL) . The ripple frequency increases at reduced load currents. 1) The curves show the behavior based on characterization data.
