PROFET® Data sheet BTS 6144B/P

Smart Highside Power Switch

Reversave

• Reverse battery protection by self turn on of

power MOSFET

Features

• Short circuit protection with latch

• Current limitation

• Overload protection

• Thermal shutdown with restart

• Overvoltage protection (including load dump)

• Loss of ground protection

• Loss of Vbb protection (with external diode for

charged inductive loads)

• Very low standby current

• Fast demagnetization of inductive loads

• Electrostatic discharge (ESD) protection

• Optimized static electromagnetic compatibility

(EMC)

Diagnostic Function

• Proportional load current sense (with defined fault

signal in case of overload operation, overtemperature shutdown and/or short circuit shutdown)

Application

• Power switch with current sense diagnostic feedback for 12V and 24 V DC grounded loads

• All types of resistive, inductive and capacitive loads

• Replaces electromechanical relays, fuses and discrete circuits

General Description

N channel vertical power FET with charge pump, current controlled input and diagnostic feedback with load

current sense, integrated in Smart SIPMOS chip on chip technology. Providing embedded protective functions.
