LTC4287
Overview
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.
- 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
