TDF1779A
TYPICAL APPLICATION WITH TDF1779A TWO LOADS 12 V - 2 A
Load : RC = 6 Ω
The external Zener diode must dissipate the power stored in the inductance LC.
R1min = VCC/4 mA, R2min = VCC/4 mA, Rmax = VCC/1 mA.
MAIN FEATURES
This application is protected against for short circuit and overload.
The load disconnection is detected when inputs E1 and E2 are low and the sense output is high.
When thermal protection is actived the pin 9 is low. Inputs are TTL compatible.
Sense output, Alarm output are open collector.
