应用功能:Solid State 1 Amp Switch The LM1951 is a high current, high voltage, high side (PNP)switch with a built-in error detection circuit. The LM1951 is guaranteed to deliver 1 Amp output current and is capable of withstanding uptog85V transients. The built-in error detection provides an error flag output underthe following fault conditions: output short to ground or supply,open load,The LM1951 will drive all types of resistive or inductive loads. The output has a built-in negative voltage clamp(& b30V)
