ADM1281-1ACPZ - Hot-Swap Controller and Digital Power and Energy Monitor with PMBus Interface
Product Overviews
ADM1281-1ACPZ is a hot-swap controller that allows a circuit board to be removed from or inserted into a live backplane. It also features current, voltage, power, and temperature readback through an integrated 12-bit analog-to-digital converter (ADC), accessed using a PMBus™ interface. The ADM1281 features overvoltage (OV) and undervoltage (UV) protection, programmed using external resistor dividers on the UV and OV pins. A PWRGD signal can be used to detect when the output supply is valid, using the PWGIN pin to accurately monitor the output.
Key Features
±0.3% accurate, 12-bit ADC for IOUT, VIN, VOUT, and temperature
290 ns response time to short-circuit
Shutdown on detection of FET health fault
Constant power foldback for tighter FET SOA protection
Remote temperature sensing with programmable warning and shutdown thresholds
Resistor-programmable 5 mV to 25 mV VSENSE current limit
Programmable start-up current limit
1% accurate UV, OV, and PWRGD thresholds
Split hot-swap and power monitor inputs to allow additional external ADC filtering
Reports power and energy consumption over time
Peak detect registers for current, voltage, and power
PROCHOT power throttling capability
PMBus fast mode compliant interface
Available in 5 mm × 5 mm, 32-lead LFCSP package
