750 Ma High Side Switch - National Semiconductor

The LM1950 is a high current, high side (PNP) power Switch for driving ground referenced loads. Intended for industrial and automotive applications the LM1950 is guaranteed to deliver 750 mA continuous load current (with typically 1.4 Amps peak) and CAN withstand supply voltage transients up to a60V and b50V. When switched OFF the quiescent current drain from the input power supply is less than 100 mA which CAN allow continuous connection to a battery power source. The LM1950 will drive all types of resistive or reactive loads. To obtain a rapid decay time of the energy in inductive loads, the output is internally protected but not clamped and CAN swing below ground to at least 54V negative with re- spect to the input power supply voltage. The ON/OFF input CAN be driven with standard 5V TTL or CMOS compatible Logic levels independent of the VCC sup- ply voltage used. Built in protection features include short Circuit Protection thermal shutdown, over-voltage shutdown to protect load circuits and protection against reverse polari- ty input connections. The LM1950 is available in a 5-lead power TO-220 package and specified over a wide b40Cto 125C operating temperature range. By National Semiconductor Corporation
