HIP1020集成电路（IC）的热插拔控制器规格书PDF中文资料

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.
