Thông số kỹ thuật
ACS716KLATR-6BB-T is an Allegro MicroSystems open-loop galvanically isolated linear Hall-effect current sensor with integrated overcurrent fault detection, designed for precise bidirectional AC and DC current monitoring in compact 3.3V low-power power conversion, motor drive and battery management equipment.
👉 It’s not a low-bandwidth basic current sense chip without fault protection.
👉 It’s a high-speed, high-noise-immunity isolated current sensor with user-configurable overcurrent alarm for space-limited industrial and consumer power systems.
Key Features of ACS716KLATR-6BB-T Current Sensor IC
Power hardware and embedded designers select ACS716KLATR-6BB-T for its compact form factor, fast response and robust high-voltage switching noise suppression:
- ±6 A bidirectional AC/DC current sensing range with fixed 100 mV/A sensitivity
- 2400 Vrms galvanic isolation between primary power track and low-voltage signal circuitry
- Ultra-low 1 mΩ internal primary conductor resistance to reduce power loss and self-heating
- Patented integrated internal shielding suppresses high dv/dt capacitive coupling interference from switching power rails
- 120 kHz wide analog bandwidth with only 4 μs typical signal response time for fast current loop control
- User-adjustable overcurrent fault threshold via VOC pin; fault flag triggers within <2 μs for rapid circuit protection
- Dedicated external filter pin to tune bandwidth and lower measurement noise for low-frequency monitoring tasks
- Single 3 V–3.6 V supply voltage, fully optimized for 3.3V MCU logic circuits, max 11 mA quiescent supply current
- Chopper-stabilized Hall architecture delivers ultra-stable zero-current output voltage and minimal magnetic hysteresis
- Factory pre-trimmed sensitivity and offset voltage to eliminate secondary system calibration steps
- Ratiometric analog output centered at half the supply voltage under zero current condition
- High precision performance: ±0.25% full-scale linearity, ±2.2% total output accuracy at 25°C
- 16-SOIC wide-body surface mount package, tape-and-reel (TR) shipping format for mass SMT assembly
- Extended industrial operating temperature range: -40°C to +125°C
- RoHS 3 compliant lead-free construction, MSL 3 moisture sensitivity rating
