PRODUCT BRIEF

Power PROFET™ + 24/48V

Ultra low-ohmic smart high-side switches in TOLL package

The Power PROFET™ + 24/48V smart high-side switch family provides a very

low R_DS(on)– one variant down to 1.5 mΩ – in a small 8-pin leadless power

package (HSOF-8). The ability to drive high current loads up to 35 amperes

and its state of the art integrated protections and diagnosis features makes

Power PROFET™ + 24/48V ideally suited to replace electromechanical relays,

fuses and discrete circuits in power distribution and other high current

applications in a 24 V or 48 V board net.

Key features

‒ 24/48 V lowest-ohmic high side

switches with integrated pro-

tection and diagnosis features

‒ Extended voltage range

8 … 60 V

‒ Protection: short-circuit

with latch, overtemperature

with latch, smart clamping,

overpower shutdown, ground

loss protection

Severe automotive requirements like load dump, short circuit, low battery

voltage during the cranking and low impact on EMC in PWM operation are

fully met. The current (dk_ILIS) accuracy especially at low current allows a

reliable diagnosis feature at system level.

‒ Load dump robustness up to

70 V

‒ Diagnosis: load current sense

output and short circuit,

overtemperature, open load

detection on/oﬀ state

The Power PROFET™ + 24/48V devices are automotive qualified and PRO-SIL™

ISO 26262-ready and come with a safety application note to facilitate the

usage in functional safety-related applications.
