Dual Power Distribution Controller
The HIP1012A 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 10µA 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.
Overcurrent 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
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.
Ordering Information
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
