HC16F 1000-S01 Open-Loop Hall Effect Current Transducer

HC16F 1000-S01 Product Overview

The HC16F 1000-S01 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 SMD (surface-mount device) version is specifically engineered for automotive motor control applications, including electrical power steering (EPS), starter generators, and converters .

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, very good linearity, and extremely low thermal offset and sensitivity drift . The dual-ASIC configuration provides high immunity to external magnetic interference (cross-talk) .

Rated for 1000 A nominal with a 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% and linearity is very good . Frequency bandwidth is DC to 40 kHz . Supply voltage range is 4.85 to 5.15 V DC (unipolar) . Maximum RMS primary admissible current is defined by the busbar to have T < +150°C . Operating temperature range is -40°C to +125°C . The design is compact for PCB mounting with dimensions of 37.2 x 32.6 mm and a mass of 29 g . Housing is PPS-I-(GF + MD) 50 and the package type is SMD (S01 version) . Applications include automotive electrical power steering, starter generators, converters, and motor drive applications . Product status is Active.

HC16F 1000-S01 Key Advantages

The HC16F 1000-S01 features a compact, lightweight design (29 g, 37.2 x 32.6 mm) that enables direct mounting on gate driver boards in inverter systems, saving valuable board space . The open-loop Hall effect technology with proprietary ASIC delivers excellent accuracy, very good linearity, and extremely low thermal offset and sensitivity drift over temperature . The dual-ASIC configuration provides superior immunity to external magnetic fields, effectively eliminating cross-talk from adjacent conductors .

The circular aperture accommodates both rectangular and round busbars, offering flexibility in busbar design . The SMD version (S01) supports automated PCB assembly, reducing manufacturing costs . 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 .
