Single, Double or Triple-Output Hot Plug
Controller
The HIP1020 applies a linear voltage ramp to the gates of
any combination of 3.3V, 5V, and 12V MOSFETs. The
internal charge pump doubles a 12V bias or triples a 5V bias
to deliver the high-side drive capability required when using
more cost-effective N-Channel MOSFETs. The 5V/ms ramp
rate is controlled internally and is the proper value to turn on
most devices within the Device-Bay-specified di/dt limit. If a
slower rate is required, the internally-determined ramp rate
can be over ridden using an optional external capacitor.
When VCC = 12V, the charge pump ramps the voltage on
HGATE from zero to 22V in about 4ms. This allows either a
standard or a logic-level MOSFET to become fully enhanced
when used as a high-side switch for 12V power control. The
voltage on LGATE ramps from zero to 16V allowing the
simultaneous control of 3.3V and/or 5V MOSFETs.
When VCC = 5V, the charge pump enters voltage-tripler
mode. The voltage on HGATE ramps from zero to 12.5V in
about 3ms while LGATE ramps to 12.0V. This mode is ideal
for control of high-side MOSFET switches used in 3.3V and
5V power switching when 12V bias is not available.
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.

... Data Sheet Single, Double or Triple-Output Hot Plug Controller The HIP1020 applies a linear voltage ramp to the gates of any combination of 3.3V, 5V, and 12V MOSFETs.

... HIP1020 DESCRIPTION Connect this pin to either a 12V source. The HIP1020 detects the bias-voltage level at pin 1 and decides whether to operate as a voltage-doubler or a voltage-tripler. Consequently not recommended to operate with bias voltages between 5V (±10%) and 12V (±10%). In the absence of an enable signal at pin 5, the current into pin 1 is less than 1µ necessary for voltage to be present at pin 1 prior to applying an enable signal at pin 5 ...

... MOSFETs controlling voltages other than 12V, 5V, or 3.3V provided three basic constraints are observed. The first constraint is that the bias voltage for the HIP1020 is either 12V or 5V. Chip operation at voltages significantly below 5V is not possible, while a bias voltage very much above 12V can unnecessarily stress the part. Operation between 5V and 12V can “ ...
