LM5066I provides robust protection and precision monitoring
for 10- to 80-V systems. Programmable UV, OV, ILIMIT, and fast-short circuit
protection allow for customized protection for any application. Programmable FET SOA protection
sets the maximum power the FET is allowed to dissipate under any condition. The programmable fault
timer (tFAULT) is set to avoid nuisance trips, ensure start-up, and limit
the duration of over load events.
In addition to circuit protection, the LM5066I supplies
real-time power, voltage, current, temperature, and fault data to the system management host
through the I2C / SMBus interface. PMBus compliant command structure
makes it easy to program the device. Precision telemetry enables intelligent power management
functions such as efficiency optimization and early fault detection. LM5066I also supports advanced features such as I/V/P averaging and peak power
measurment to improve system diagnostics.
LM5066I is pin-to-pin compatible with the LM5066 and offers improved telemetry accuracy
and supports the Read_Ein command to monitor energy. See for a detailed comparison.
