The Power PROFET™ + 24/48V smart high-side switch family provides a very low RDS(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 electro mechanical relays, fuses and discrete circuits in power distribution and other high current applications in a 24 V or 48 V board net. 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 (dkILIS) accuracy especially at low current allows a reliable diagnosis feature at system level. 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. PRODUCT BRIEF Power PROFET™ + 24/48V Ultra low-ohmic smart high-side switches in TOLL package ‒ 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 ‒ Load dump robustness up to 70 V ‒ Diagnosis: load current sense output and short circuit, overtemperature, open load detection on/off state ‒ Diagnosis Enable Pin (DEN) for MCU input multiplexing Key features ‒ Fully integrated solution with low stand-by current (7 µA) ‒ Supports long wires ‒ Leadless power package with good thermal performance ‒ Outstanding current sense accuracy ±5% after calibration ‒ Very low offset on the current sense: for high accuracy at low load current Key benefits ‒ Fuse and relay replacement ‒ Heating: rear defogger, glow plugs and PTC ‒ Fan and pump ‒ Power distribution Key applications www.infineon.com/powerprofet Block diagram Gate control and charge pump Overcurrent switch-off ESD protection Load current sense OUT IS VS DEN GND IN Driver logic ESD protection Temperature sensor Voltage sensor Smart clamp
