HC16F 1000-S00 Open-Loop Hall Effect Current Transducer

HC16F 1000-S00 Product Overview

The HC16F 1000-S00 is an open-loop Hall effect current transducer from LEM's HC16F series, designed for the electronic measurement of DC, AC, and pulsed currents in high-power automotive applications with galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit) . This through-hole (THD) version is specifically engineered for automotive motor control applications, including electrical power steering (EPS), starter generators, converters, and motor drives .

The HC16F series employs open-loop Hall effect technology combined with LEM's proprietary ASIC and a specially designed dual air-gap magnetic core, delivering excellent accuracy and very good linearity . The transducer features a housing with a sleeve that provides insulation for busbars and meets high-voltage isolation requirements in automotive systems .

Rated for 1000 A nominal with a bidirectional measuring range of ±1000 A, it outputs an instantaneous ratiometric voltage signal of 2.5 V ± 2 V at rated current . Accuracy is 1.75% with a sensitivity of 2.00 mV/A . Frequency bandwidth is DC to 40 kHz . Supply voltage range is 4.85 to 5.15 V DC (unipolar, 5 V nominal) . Maximum RMS primary admissible current is defined by the busbar to have T < +150°C . Delay time to 90% of the final output value for an IPN step is 2 to 4 µs . Operating temperature range is -40°C to +125°C . Mass is 29 g with a compact design for PCB mounting. Housing is PPS-I-(GF+MD) 50 with a bronze tin-plated lead frame . The product is AEC-Q100 Grade 1 qualified (automotive qualified) . Product status is Active.

HC16F 1000-S00 Key Advantages

The HC16F 1000-S00 features a compact, lightweight design (29 g) that enables direct mounting on gate driver boards in inverter systems, saving valuable board space . The open-loop Hall effect technology combined with LEM's proprietary ASIC and specially designed dual air-gap magnetic core delivers excellent accuracy, very good linearity, and extremely low thermal offset and sensitivity drift over temperature .

The circular aperture accommodates both rectangular and round busbars, offering flexibility in busbar design . The S00 (through-hole) version simplifies PCB assembly. The housing features a sleeve that passes through the PCB, providing insulation for busbars and meeting high-voltage isolation requirements in automotive systems . The ratiometric output (full ratiometric in sensitivity and offset) simplifies integration with ADC-based control systems . The unipolar 5 V supply and automotive-qualified specification (AEC-Q100 Grade 1) ensure robust performance in demanding automotive environments .
