Product Summary

The LM1951T is a high current, high voltage, high side (PNP) switch with a built-in error detection circuit. The LM1951T is guaranteed to deliver 1 Amp output current and is capable of withstanding up to g85V 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 shut-down. The LM1951T will drive all types of resistive or inductive loads. The output has a built-in negative voltage clamp to provide a quick energy discharge path for inductive loads. The LM1951T 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 LM1951T features make it well suited for industrial and automotive applications.
