High-side Power Switch ICs
[With Diagnostic Function, 3-circuits]
SLA2501M
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)
0.2V)
●
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

Note:
* The Zener diode has an energy capability of 200 mJ (single pulse).
* A start failure may occur if a short OFF signal of 10 ms or below is input in the V
IN
terminal.
