Teknik Özellikler
ACS758LCB-100B-PFF-T is a thermally enhanced Allegro MicroSystems open-loop galvanically isolated linear Hall-effect current sensor, engineered for accurate bidirectional AC/DC high-current measurement up to ±100A in high-power industrial, new energy and motor drive equipment.
👉 It’s not a low-current surface-mount small signal current sensor.
👉 It’s a high-current through-hole isolated sensing solution optimized for high voltage power conversion, heavy-load motor control and energy storage systems.
Key Features of ACS758LCB-100B-PFF-T Current Sensor IC
Power system and automation engineers select ACS758LCB-100B-PFF-T for its ultra-low loss, strong noise immunity and wide temperature stability:
- ±100A bidirectional AC/DC current detection range with 20mV/A fixed sensitivity at 5V supply
- Ultra-low 100 μΩ integrated primary copper conductor, drastically cutting power dissipation and self-heating under high loadAllegro
- 4800 Vrms reinforced galvanic isolation between high-current power track and low-voltage signal circuitry for safety complianceAllegro MicroSystems
- Patented internal magnetic shielding suppresses high dv/dt capacitive coupling noise from fast-switching power rails, minimizing output offset drift
- 120 kHz analog bandwidth with only 4 μs typical fast response time for real-time current closed-loop control
- Chopper-stabilized monolithic Hall IC design delivers near-zero hysteresis and consistent linear output performance
- Single wide supply voltage range of 3.0 V to 5.5 V, fully compatible with 3.3V and 5V industrial control MCUs
- Factory pre-calibrated gain and offset voltage with built-in temperature compensation to maintain high accuracy across full operating temperature
- Ratiometric analog output centered at half supply voltage under zero current, directly connectable to ADC chips
- PFF through-hole formed lead package, tube packaging format for reliable high-current wiring assembly
- Extended industrial operating temperature range: -40°C to +150°C for harsh high-temperature power equipment environmentsAllegro MicroSystems
- RoHS3 lead-free compliant construction, matte tin lead frame compatible with standard welding processes
- Industry-leading low noise performance via proprietary amplifier and filter circuit design
