Dual Power Distribution Controller
The HIP1012 is a HOT SWAP dual supply power distribution
controller. Two external N-Channel MOSFETs are driven to
distribute power while providing load fault isolation.
At turn-on, the gate of each external N-Channel MOSFET is
charged with a 10 A current source. Capacitors on each
gate (see the Typical Application Diagram), create a
programmable ramp (soft turn-on) to control inrush currents.
A built in charge pump supplies the gate drive for the 12V
supply N-Channel MOSFET switch.
Over current protection is facilitated by two external current
sense resistors. When the current through either resistor
exceeds the user programmed value the controller enters the
current regulation mode. The time-out capacitor, C
charging as the controller enters the time out period. Once
C
are latched off. In the event of a fault at least three times the
current limit level, the N-Channel MOSFET gates are pulled
low immediately before entering time out period. The
controller is reset by a rising edge on either PWRON pin.
Choosing the voltage selection mode the HIP1012 controls
either +12V/5V or +3.3V/+5V supplies.
For those applications where voltage tolerance is a concern
the HIP1012A has a minimum nominal over current threshold
voltage of 50mV as compared to 100mV for the HIP1012.
