Product Details

Description



Features:

• Operates from -20V to -80V (-100V Absolute Max Rating)
• Programmable Inrush Current
• Programmable Time-Out
• Programmable Current Limit
• Programmable Over-Voltage Protection
• Programmable Under-Voltage Protection
- 135 mV of hysteresis ~4.7V of hysteresis at the power supply
• VDD Under-Voltage Lock-Out (UVLO) ~ 16.5V
• IntelliTripTM Electronic Circuit Breaker distinguishes between severe and moderate faults
- Fast shutdown for short circuit faults with a single retry (fault current > 4X current limit value).
• FAULT pin reports the occurrence of an Over-Current Time-Out
• Disable input controls GATE shutdown and resets Over-Current fault latch
• Load Current Monitor Function
- ISOUT provides a scaled version of the load current
- A resistor from ISOUT to -VIN provides current to voltage conversion
• Power Good Control Output
- Output latched "good" when DRAIN and GATE voltage thresholds are met.
- (PWRGD active low: ISL6142 (L version)
- PWRGD active high: ISL6152 (H version)
• Pb-free available





Application

• VoIP (Voice over Internet Protocol) Servers
• Telecom systems at -48V
• Negative Power Supply Control
• +24V Wireless Base Station Power

Description

The ISL6142/52 are 14 pin, negative voltage hot plug controllersthat allow a board to be safely inserted and removed from a livebackplane. Inrush current is limited to a programmable value bycontrolling the gate voltage of an external N-channel passtransistor. The pass transistor is turned off if the input voltage isless than the Under-Voltage threshold, or greater than the Over-Voltage threshold. The PWRGD/PWRGD outputs can be used todirectly enable a power module. When the Gate and DRAINvoltages are both considered good the output is latched in theactive state.The IntelliTrip™ electronic circuit breaker and programmablecurrent limit features protect the system against short circuits.When the Over-Current threshold is exceeded, the output currentis limited for a time-out period before the circuit breaker trips andshuts down the FET. The time-out period is programmable with anexternal capacitor connected to the CT pin. If the fault disappearsbefore the programmed time-out, normal operation resumes. Inaddition, the IntelliTrip™ electronic circuit breaker has a fast HardFault shutdown, with a threshold set at 4 times the Over-Currenttrip point. When activated, the GATE is immediately turned off andthen slowly turned back on for a single retry.The IS+, IS-, and ISOUT pins combine to provide a load currentmonitor feature that presents a scaled version of the load currentat the ISOUT pin. Current to voltage conversion is accomplishedby placing a resistor (R9) from ISOUT to the negative input (-48V).
