With a primary current measuring range from ±40A to ±100A, the HAB 60-S family of current transducers for automotive battery-monitoring applications measure dc, ac, or pulsed currents. An integrated ASIC ensures a resolution 2.5 times better than previous models and a two-fold improvement in offset error. The transducers rely on open-loop, Hall-effect technology to ease installation and servicing by removing the need to cut the primary cable. They provide a PWM output signal proportional to the primary current and operate from a 5V supply. Temperature measurement capability is also available via a fourth connection pin to the transducer package. Output resolution is 0.03A with a 0.2% linearity offset error is typically 0.075A across a temperature range from -10°C to +65°C, and 0.15 A across the full range from -40°C to +125°C.
