LTC4287規(guī)格書詳情
GENERAL DESCRIPTION
The LTC4287 is an integrated solution for hot swap applications
that allows a board to be safely inserted and removed from a live
backplane. The dual-gate drivers coupled with configurable multimode
startup sequencing and operation optimize the metal-oxide
semiconductor field-effect transistor (MOSFET) safe operating area
(SOA) for a variety of power levels. The circuit breaker timer limits
the MOSFET temperature for reliable protection against overstress.
The SMBus 3.1 interface, PMBus command structure, and onboard
analog-to-digital converters (ADCs) with selectable resolution
and speed allow monitoring of board current, voltage, power, energy,
temperature, and fault status. An optional external, electrically
erasable programmable read only memory (EEPROM) can be used
for part configuration and provide BlackBox capturing of past fault
conditions.
The LTC4287 has additional features to respond to input undervoltages
and overvoltages, to interrupt the host when a fault has occurred,
to notify when the output power is good, to detect insertion
of a board, to turn off the MOSFET if an external supply monitor
fails to indicate power-good within a timeout period, and to auto
reboot after a programmable delay following a host commanded turn-off.
FEATURES
? Drives two gates for high power applications
? Wide input supply voltage range: 6.5 V to 80 V
? Optimizes MOSFET SOA with multimode start-up sequencing
and operation
? Monitors currents, voltages, power, and energy with the ADC
? Limits MOSFET temperature for overstress protection
? Adjustable, 6.6% accurate (5 mV) current limit with foldback
? BlackBox capturing and configuration using an optional external
EEPROM
? SMBus 3.1 interface and PMBus-compliant command structure
? Parallelable controllers for high current levels
? Minimum and maximum ADC measurements logging with alerts
? Available in 48(39)-lead plastic QFN (7 mm × 7 mm) package
? Configurable current foldback
APPLICATIONS
? High availability server backplane systems
? 12 V/24 V/48 V/54 V distributed power systems
