ISL6141規(guī)格書詳情

The ISL6141 is an 8-pin, 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 Nchannel pass transistor. The pass transistor is turned off if

the input voltage is less than the Under-Voltage threshold, or

greater than the Over-Voltage threshold. The IntelliTripTM

electronic circuit breaker and programmable current limit

features protect the system against short circuits. When the

Over-Current threshold is exceeded, the output current is

limited for 600μs before the circuit breaker shuts down the

FET. If the fault disappears before the 600μs time-out,

normal operation resumes. In addition, the IntelliTripTM

electronic circuit breaker has a fast Hard Fault shutdown with

a threshold set at 4 times the current limit value. When

activated, the GATE is immediately turned off and then

slowly turned back on for a single retry (soft-start). The

active low PWRGD signal can be used to directly enable a

power module (with a low enable input). The ISL6151 is the

same device but has an active high PWRGD output.

Features

? Operates from -20V to -80V (-100V Absolute Max Rating)

? Programmable Inrush Current

? Programmable Over-Voltage Protection

? Programmable Under-Voltage Protection

- 135mV of hysteresis

- Equals ~4.6V of hysteresis at the power supply

? UVLO (Under-Voltage Lock-Out) ~ 16.5V

? Programmable Current Limit with 600μs time-out

? IntelliTripTM electronic circuit breaker distinguishes

between Over-Current and Hard Fault conditions

- Fast shutdown for Hard Faults with a single retry (fault

current > 4X current limit value).

? Pin Compatible with ISL6140/50.

? Power Good Control Output

- Monitors both the DRAIN (voltage drop across the FET)

and the GATE voltage; once both are OK, the Power

Good output is latched in the active state.

- PWRGD active high: ISL6151 (H version)

- PWRGD active low: ISL6141 (L version)

? Pb-free available

Applications

? VoIP (Voice over Internet Protocol) Servers

? Telecom systems at -48V

? Negative Power Supply Control

? +24V Wireless Base Station Power
