SC1205
POWER MANAGEMENT
Applications Information (Cont.)
Proper layout will guarantee minimum ringing and elimi-
nate the need for external components. Use of SO-8 or
other surface mount MOSFETs while increasing thermal
resistance, will reduce lead inductance as well as radi-
ated EMI.
Over Temp Shutdown
The SC1205 will shutdown by pulling both driver if its
junction temperature, T , exceeds 165 °C.
