HIP1020

Single, Double or Triple-Output Hot Plug Controller

DATASHEET

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.

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.
