±20A Integrated Current Sensor  
FEATURES  
DESCRIPTION  
Integral Non-inductive Current Sense  
Element with Internal Kelvin  
Connections  
The UCC3926 Current Sensor IC contains a wideband, transimpedance  
amplifier for converting the current through an internal, non-inductive  
1.3mshunt resistor into a proportional voltage. The sense element oper-  
ates in both high-side (VDD referenced) and low-side (GND referenced) ap-  
plications.  
20A Current Rating  
Bi-directional, High Side or Low Side  
The UCC3926 can measure currents up to ±20A. This transimpedance am-  
plifier gain is precisely trimmed to 33.3mto 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.

Status Output  
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.
