ISL6150集成電路（IC）的熱插拔控制器規(guī)格書(shū)PDF中文資料

The ISL6140 is an 8 Ld, negative voltage hot plug

controller that allows a board to be safely inserted and

removed from a live backplane. Inrush current is limited

to a programmable value by controlling the gate voltage

of an external N-channel pass transistor. The pass

transistor is turned off if the input voltage is less than the

undervoltage threshold, or greater than the overvoltage

threshold. A programmable electronic circuit breaker

protects the system against shorts. The active low

PWRGD signal can be used to directly enable a power

module (with a low enable input)

The ISL6150 is the same part, but with an active high

PWRGD signal.
