LM1951 - National Semiconductor

LM1951 LM1951 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 up to g 85V transients The built-in error detection provides an error flag output under the following fault conditions output short to ground or supply open load curre.

Features

TTL and CMOS compatible logic input with hysteresis Switching times both turn on and turn off are 2 ms (Cload k 0 005 mF) In addition its quiescent current in the OFF state is typically less than 0 1 mA at room temperature and less than 10 mA over the entire operating temperature and voltage range The LM1951 features make it well suited for industrial and automotive applications Features Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y 0 1 mA typical quiescent current (OFF state) 1 Amp output current guaranteed g 85V transient protection Reverse voltage protection Negative output voltage clamp Error flag out.
