± 20A Integrated Current Sensor

The UCC3926 Current Sensor IC contains a wideband, transimpedance Amplifier for converting the current through an internal, non-inductive 1.3m shunt resistor into a proportional voltage. The sense element oper- ates in both high-side (VDD referenced) and low-side (GND referenced) ap- plications. The UCC3926 CAN measure currents up to 20A. This transimpedance am- plifier gain is precisely trimmed to 33.3m to convert a 15A input into a 500mV output signal. It has a very low input offset voltage from chop- per-stabilization. A cross-switching block rectifies the input signal by forcing the differential output, AOP positive with respect to the other differential output, AON. SIGN indicates the polarity of the current. The UCC3926 programmable Amplifier provides three functions. It converts the differential transimpedance output signal into a single-ended signal. It has a user-controlled gain stage that sets the maximum current level to the desired voltage and it level shifts the zero current point to the desired level as well. A Comparator then compares the output of the instrumentation am- plifier to a user-set reference voltage on OCREF, which provides an overcurrent status bit OC. The UCC3926 is available in the 16 pin SOIC package. By Texas Instruments
