LM1951 Solid State 1 Amp Switch

General Description

The LM1951 is a high current, high voltage, high side (PNP)

switch with a built-in error detection circuit.

Features

0.1 mA typical quiescent current (OFF state)

1 Amp output current guaranteed

85V transient protection

The LM1951 is guaranteed to deliver 1 Amp output current

and is capable of withstanding up to 85V transients. The

Reverse voltage protection

Negative output voltage clamp

Error flag output

built-in error detection provides an error flag output under

the following fault conditions: output short to ground or sup-

ply, open load, current limit, overvoltage or thermal shut-

down. The LM1951 will drive all types of resistive or induc-

tive loads. The output has a built-in negative voltage clamp

Internal overvoltage shutdown

30V) to provide a quick energy discharge path for

inductive loads. The LM1951 features TTL and CMOS com-

(

High speed switching (up to 50 kHz)

Inductive or resistive loads

Low ON resistance (1X maximum)

patible logic input with hysteresis. Switching times, both turn

on and turn off, are 2 ms (C

0.005 mF). In addition, its

load

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.

TTL, CMOS compatible input with hysteresis

Plastic TO-220 5-lead package

ESD protected

The LM1951 features make it well suited for industrial and

automotive applications.
