SGM25716L

The SGM25716L is a high-performance hot-swap controller for 10V to 90V system with an SMBus/I2C interface compliant with PMBus standards. Via the SMBus interface, the SGM25716L provides continuous real-time monitoring of power, voltage, current, temperature, and fault conditions through the SMBus/I²C interface, reporting all data to the system management host. 

The SGM25716L delivers current and power limiting capabilities, which safeguard sensitive circuitry when boards are inserted into a live system backplane or any other active power source. Additionally, a rapid-response circuit breaker prevents damage if a short circuit occurs at the output. Key parameters such as input under-voltage and over-voltage levels, hysteresis, insertion delay time, and fault detection time are all configurable. The SGM25716L also features a temperature monitoring module that interfaces with a low-cost external diode. This diode is used to monitor the temperature of external MOSFETs or other thermally sensitive components. The power good output serves as a quick indicator whenever input or output voltages deviate from their programmed ranges.

The monitoring module of the SGM25716L calculates two types of values for subsystem operating parameters (V_IN, I_IN, P_IN, V_OUT): real-time values and average values. It also computes the peak power of the subsystem. Accurate power averaging is achieved by calculating the average of the product derived from input voltage and input current.

The SGM25716L is featuring enhanced telemetry accuracy and support for the READ_EIN command for energy monitoring.

The SGM25716L is available in a Green TSSOP-28 (Exposed Pad) package.
