Sanken Electric Co SLA2501M Datasheet
3-circuit High-side Power Switch Array SLA2501M
32
Features
● Built-in diagnostic function to detect short and open circuiting of loads and
output status signals
● Low saturation PNP transistor use (V
CE (sat)
● Allows direct driving using LS-TTL and C-MOS logic levels
● Built-in Zener diode in transistor eliminates the need of (or simplifies) external
surge absorption circuit
● Built-in independent overcurrent and thermal protection circuit in each circuit
● Built-in protection against reverse connection of power supply
● Tj = 150ºC guaranteed
