HV300LG数据手册集成电路（IC）的热插拔控制器规格书PDF

描述 Description

General Description
The Supertex HV300 (and HV310), Hotswap Controller, Negative Supply control power supply connection during insertion of cards or modules into live backplanes. They may be used in traditional ‘negative 48V’ powered systems or for higher voltage busses up to negative 90V.
Operation during the initial power up prevents turn-on glitches, and after complete charging of load capacitors (typically found in filters at the input of DC-DC converters) the HV300 (and HV310) issues a power good signal. This signal is typically used to enable the DC-DC converter.
