HIP1020, Hot Plug Controller

PIN SYMBOL FUNCTION DESCRIPTION 1 VCC Bias Supply 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.

Consequently, it is not recommended to operate with bias voltages b

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, t
