application

C compatible power switch with diagnostic feedback for 12 V and 24 V DC grounded loads All types of resistive, inductive and capacitive loads replace electromechanical relays, fuses and discrete circuits.

External current limit when GND is connected (e.g. resistor RGND = 150 61527 ;), resistor in series with ST

connected, the reverse load current is limited by the connected load.

data sheet

Pin symbol function

1 OUT1 (load, L) output 1, protect the high-side power output of channel 1

2 GND logic ground

3 IN1 input 1, activates channel 1 in the presence of a logic high signal

4 Vbb positive supply voltage, label shorted to this pin

5 ST diagnostic feedback: open drain, low fault

6 IN2 Input 2, activates channel 2 in the presence of a logic high signal

7 OUT2 (load, L) output 2, high-side power output for protection channel 2

Status output diagram

ESD Zener: 6.1 V typical, 5 mA max; RST(ON) < 380 , 1.6 mA, ESD Zener is not

Used as a voltage clamp under DC conditions. Operating in this mode may cause the Zener diode to drift (increase to 1 V).

Inductor and Overvoltage Output Clamp

VON is clamped to 47 V (typ).

overvoltage, and reverse battery protection.

VZ1 = 6.1 V (typ), VZ2 = 47 V (typ), RI = 3.5k (typ) RGND = 150

On-state diagnostic condition: VON

Off-State Diagnostic Condition: VOUT > 3 V (typ) at low.

GND disconnected

any kind of load. If input = high, then VOUTVIN - VIN(T+). Since VGND > 0, there is no VST = low signal available.

GND disconnected and GND pulled up

any kind of load. If VGND > VIN - VIN(T+) the device remains off due to VGND > 0, no VST = low signal available.

Vbb is disconnected with power-on induction loading

PROPHET can handle normal load current itself

Vbb is externally disconnected from the charging inductive load

Additional elements like D are necessary if other external inductive loads L are connected to PROPHET.

Inductive loads turn off energy dissipation
