Product Details

The ISL6142/52 are 14 pin, negative voltage hot plug controllers that allow 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 Under-Voltage threshold, or greater than the Over Voltage threshold. The PWRGD/PWRGD outputs can be used to directly enable a power module. When the Gate and DRAIN voltages are both considered good the output is latched in the active state.

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
• IntelliTrip™ 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

Applications

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