Sanken Electric Co SI-5151S Datasheet
High-side Power Switch with Diagnostic Function SI-5151S
Features
● Built-in diagnostic function to detect short and open circuiting of loads and
output status signals
● Low saturation PNP transistor use
● Allows direct driving using LS-TTL and C-MOS logic levels
● Built-in overcurrent and thermal protection circuits
● Built-in protection against reverse connection of power supply
● TO-220 equivalent full-mold package not require insulation mica
