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.
With the success of the PROFET™ +2 12V portfolio, a further step was taken to make use of the huge technology potential: to assess the performances of the PROFET™+2 12V family in a more accurate way, the current sense accuracy (kILIS) was tightened.
Benefits of the tighter kILIS accuracy:
- Fulfillment of OEM requirements e.g. Open Load in ON detection
- Enablement of a more precise device and load measurement
Thanks to the kILIS tightening the PROFET™+2 12V portfolio presents the best accuracy at low and nominal current range.
The two graphs on the right, show a comparison between the old and new kILIS tolerance of PROFET™+2 12V BTS7008-2EPA variant:
The table below compares the old kILIS limits of BTS7008-2EPA with the new kILIS limits from 0.02 up to 10A:
