PROFET™ + 2 12V

The PROFET™ +2 12V family provides as diagnostic feature an analog sense current with an outstanding accuracy (≤ 4% @ nominal load current). It can be used to monitor the application state as normal, overload, open load, short-circuit to ground, short-circuit to battery condition, protective switch off (overtemperature shutdown and overcurrent shutdown), protect the load and the wiring harness and monitor the output current for the purpose of controlling the output power.
The PROFET™ +2 12V family offers two variants that differ in the protection strategy mechanism: Intelligent Restart Control and Intelligent Latch. The first variant has an internal counter which counts the number of fault events (up to 7) before latching. The second variant has an internal latch which protects the output stage in case of a fault event. When the device latches, a reset can be applied to restart the counter. 

A unique benefit of the PROFET™ +2 12V family is the pin-compatibility within the single and dual-channel family devices. Based on the identical footprint of its packages, maximum design flexibility is provided, allowing a change of loads and devices without major modification of the board layout.
Compatibility with the hardest reverse battery requirement on the market (ReverseON), reduced internal operating current consumption, simplified and cost efficient ground network, outstanding current sense accuracy, benchmark cranking voltage capability (able to work down to 3.1 V), smaller package size for area savings, design flexibility across the family by pin to pin compatibility and very low output leakage current (≤ 0.5 µA up to 85°C) are the keys for the success of PROFET™ +12V in the automotive market.

PROFET™ +2 12V products provide a quick pick and place motherboard-daugtherboard approach. The motherboards serve as the basis for the evaluation kit, are compatible to all PROFET™ +2 12V daughterboards and provide easy application adaptability with all devices of PROFET™ +2 12V family.

The newly released PROFET™ +2 12V products BTS70012-1ESP, BTS70015-1ESP & BTS70020-1ESP are equipped with the latest feature, called Capacitive Load Switching Mode

Why is it complicated to switch a capacitive load?

When switching on capacitors, high-inrush currents occur, which leads to the fact that temperature protection of the smart power controller in standard condition is triggered. Thereby the device latches off and the capacitor remains uncharged.

Why is a Capacitive Load Switching Mode beneficial?

By activating the Capacitive Load Switching Mode, big input capacitors can be charged and capacitive loads can be switched in the safe operating area.  Moreover no discrete pre-charge circuitry is needed, no over-dimensioning of power switches occurs and supply stability is improved by reduction of current spikes during switch-ON.

How to activate and operate in Capacitive Load Switching Mode?

The Capacitive Load Switching Mode is an integrated product feature and can be activated by applying e.g. a 30kHz PMW signal to the IN pin. In this condition, slew rate is reduced, TJ (DYN) protection is set to a lower value and restart is activated. The capacitor gets charged by pumping and overtemperature protection remains untriggered.

PROFET™ +2 12V is the new generation of smart high-side switches for automotive and industrial applications based on SMART7 technology. The family offers a single, dual and four channel devices (from 2mΩ to 200mΩ) in PG-TSDSO-14 exposed pad package and provides state of the art diagnostics and protection features.

The family provides outstanding energy efficiency with reduced current consumption, state of the art current sense accuracy (kILIS), benchmark low cranking voltage capability and faster switching/slew rate with no impact on EMC.
The whole portfolio is qualified for automotive applications according to according to AEC-Q100 Grade 1 and AEC-Q100 Grade 0.

A very low ohmic DMOS power stage combined with protection and diagnostic features makes the PROFET™ +2 12V family suitable for resistive, inductive and capacitive loads, high inrush current loads such as lamps and can replace relays, fuses and discrete circuits.

The qualification AEC-Q100 Grade 0 makes the PROFET™ +2 12V portfolio also the perfect fit for applications with extended or/and high temperature mission profiles, under the hood applications requiring an extended junction temperature range up to 175 °C and powertrain systems such as transmission application.

The smart switches family PROFET™ +2 12V inherited the sustained technological know-how of the previous families to achieve excellence.
In addition to their different features, you can be sure, when opting for PROFET™ +2 12V, that you will have:
