HIP1020 - Hot Plug Controller

Datasheet Summary

Description

Connect this pin to either a 12V or a 5V source.

The HIP1020 detects the bias-voltage level at pin 1 and decides whether to operate as a voltage-doubler or a voltage-tripler.

Features

Rise Time Controlled to Device-Bay Specifications.
No Additional Components Required.
Internal Charge Pump Drives N-Channel MOSFETs.
Drives any Combination of One, Two or Three Outputs.
Internally-Controlled Turn-On Ramp - Optional Capacitor Selects Slower Rates.
Prevents False Turn on During Hot Insertion.
Operates using 12V or 5V Bias.
Improves Device Bay Peripheral Size Cost and Complex- ity - Minimal Component Count -.

HIP1020 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.
