LM5066 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 LM5066 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. LM5066 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.
