LM1951 Datasheet Lm1951 Solid State 1 Amp Switch

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1951 Solid State 1 Amp Switch August 1992 LM1951 Solid State 1 Amp.

General Description

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 current limit overvoltage or thermal shutdown The LM1951 will drive all types of resistive or inductive loads The output has a built-in negative voltage clamp b 30V) to provide a quick energy discharge path for ( inductive loads The LM1951

Key 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.
