The reverse load current through the intrinsic drain-source diode has to be limited by the connected load. Power dissipation is higher compared to normal operating conditions due to the voltage drop across the drain-source diode. The temperature protection is not active during reverse current operation!

The neighbour channel can be switched normally; not all paramters lay within the range of the spec Please note, that in case of an inverse current no protection function is active. The power dissipation is higher compared to normal operation in forward mode due to the voltage drop across the drain-source diode Data Sheet 7 V1.1, 2007-09-25 Smart High-Side Power Switch BTS723GW Parameter and Conditions, each of the two channels Symbol Values min typ Max IL(off) VOUT(OL) -2.0 3 2.85 -3.7 µA V VON(SC) -- 4.0 -- V Input RI Status RST Status pull up Rpull up VIN(T+) VIN(T-) ∆ VIN(T) VIN = 0.4 V: IIN(off) VIN = 5 V: IIN(on) -0.53 -1.2 1.0 -1 10 20 0.85 12 --0.25 -25 -1.2 -2.2 --15 50 kΩ kΩ kΩ V V V µA µA VST(high) VSPU = 5V: VST(low) 5.4 -- 6.1 -- -0.4 V at Tj = -40...+150°C, Vbb = 24 V unless otherwise specified Diagnostic Characteristics Open load detection current 21) Open load detection voltage Short circuit detection voltage 22) Vbb(pin 1,7,8,14) to OUT1 (pin 12,13) resp.
