742RI

The 742RI is a kind of N-channel vertical power FET with charge pump, ground referenced CMOS compatible input,monolithically integrated in Smart SIPMOS technology. It also provides embedded protective functions. It can be used in all types of resistive, inductive and capacitive loads,C compatible power switch for 12 V and 24 V DC applications and replaces electromechanical relays and discrete circuits. It is available in the P-DSO-8 package.

The following is the description on the features of the 742RI. (1) overload protection; (2) current limitation; (3) short circuit protection; (4) thermal shutdown with restart; (5) overvoltage protection (including load dump); (6) fast demagnetization of inductive loads; (7) reverse battery protection with external resistor; (8) CMOS compatible input; (9) loss of GND and loss of Vbb protection; (10) ESD - Protection; (11) very low standby current; (12) open drain diagnostic output.

What comes next is about maximum ratings of the 742RI at Tj is 25 . (1): supply voltage (Vbb) is 40 V; (2): continuous input voltage (VIN) is from -10 V to 16 V; (3): operating temperature (Tj) is from -40 to 150 ; (4): storage temperature (Tstg) is from -55 to 150 ; (5): power dissipation is 1.5 W; (6): current through input pin is ±5 mA; (7): the maximum turn-on time is 140 s at RL is 47 ; (8): the maximum turn-off time is 170 swhen RL is 47 ; (9): the maximum leakage output current of the 742RI is 12 mA at VIN is low; (10): the maximum operating current is 1.3 mA at VIN is high.
