SI-5152S Datasheet, PDF (1/2 Pages) Sanken electric – High-side Power Switch with Diagnostic Function

High-side Power Switch with Diagnostic Function SI-5152S
Features
q Built-in diagnostic function to detect short and open circuiting of loads and
output status signals
q Low saturation PNP transistor use
q Allows direct driving using LS-TTL and C-MOS logic levels
q Built-in overcurrent and thermal protection circuits
q Built-in protection against reverse connection of power supply
q Tj = 150ºC guaranteed
q TO-220 equivalent full-mold package not require insulation mica
