Hot Swap Controller with Advanced Fault Protection and Voltage Regulator Output
DESCRIPTION The X80070 is a hot swap controller that allows a board to be safely inserted and removed from a live backplane without turning off the main power supply. During insertion, the gate of an external power MOSFET is clamped low to suppress contact bounce. The under-voltage/ over-voltage circuits and the power on reset circuitry suppress the gate turn on until the mechanical bounce has ended. The X80070 turns on the gate with a slew rate to limit the inrush current and incorporates an electronic circuit breaker set by a sense resistor. After the load is successfully charged, the PWRGD signal is asserted; indicating that the device is ready to power sequence the DC-DC power bricks. At all times, the X80070 monitors for undervoltage, overvoltage, and overcurrent conditions. If any fault occurs, the gate will be immediately shut off and the PWRGD will be returned to the inactive state. The X80070 contains overvoltage, undervoltage and overcurrent detection, hardshort retry, gate control slew rate and power good control.
FEATURES · Hot swap controller -- Overvoltage and undervoltage protection -- Undervoltage lockout for battery/redundant supplies -- Electronic circuit breaker -- Slew Rate for External FET Gate Control -- Overcurrent Detection and Gate Shut-off -- 3X overcurrent limit on insertion -- 5µs overcurrent filter -- Hardshor t Retry and Indicator -- Typically operates from -30V to -80V. Tolerates transients to -200V (limited by external components) -- Positive Voltages (low side switching) from 12V to 60V -- Soft Re-insertion -- Soft extraction · Voltage Regulator Output for Supervisory Functions · Debounced manual reset input · Available packages -- 20-lead Quad No-Lead Frame (QFN) APPLICATIONS · -48V Hot Swap Power Backplane/Distribution Central Office, Ethernet for VOIP · Positive Voltage Hotswap 12V to 60V Applications (low side switching) · Card Insertion Detection · IP Phone Applications · Databus Power Interfacing · Custom Industrial Power Backplanes · Distributed Power Systems
