HIP1012A Description and Operation
The HIP1012A is a multifeatured dual power supply
distribution controller, including programmable current
limiting regulation and time to latch off. Additionally the
HIP1012A operates both as a +3.3V and 5V or a +5V and
+12V power supply controller with each mode having
appropriate UnderVoltage (UV) fault notification levels.
Upon initial power up HIP1012A can either isolate the
voltage supply from the load by holding the external
N-Channel MOSFET switches off or apply the supply rail
voltage directly to the load for true hot swap capability. In
either case the HIP1012A turns on in a soft start mode
protecting the supply rail from sudden current loading. If
either PWRON pin is pulled low the HIP1012A will be in
true hot swap mode. Both PWRON pins must be high to
turn off the HIP1012A thus isolating the power supply from
the load through the external FETs.

TEST CONDITIONS
At turn-on, the gate capacitor of each external N-Channel
MOSFET is charged with a 10µA current source. These
capacitors create a programmable ramp (soft turn-on). A
charge pump supplies the gate drive for the 12V supply
switch driving that gate to 17V.
The load currents pass through two external current sense
resistors. When the voltage across either resistor exceeds
the user programmed Overcurrent (OC) voltage threshold
value, (see Table 1) the controller enters current regulation.
At this time the time-out capacitor, C
a 10µA current source and the controller enters the time out
period. The length of the time out period is set by the single
external capacitor (see Table 2) placed from the C
(pin 10) to ground and is characterized by a lowered gate
drive voltage to the appropriate external N-Channel
MOSFET. Once C
is tripped resulting in both N-Channel MOSFETs being
latched off.
