uP1901中文资料High Accuracy Power Meter with I2C Interface for DC/DC Converters数据手册uPI(UBIQ)规格书

描述 Description

The uP1901 is a high-accuracy power meter for DC/DCconverter. It measures input/output currents and voltageswith zero offset sensing amplifiers. The sensed currentsand voltages are digitalized and interfaced withmicroprocessor by I2C for advanced power managementprocedures.

Ten temperature sensing inputs are available formonitoring temperature of the system. The uP1901features a current output that enables dynamic adjustmentof the output voltages. The uP1901B also features twoopen-drain outputs D0/D1 for indicating the instant outputcurrent level.

Other features include programmable I2C address, highaccuracy reference output voltage. This part is availablein VQFN4x4 - 24L or VQFN5x5 - 32L.
