Product details
Overview
TLE4984CXAAF47XAMA1 from Infineon Technologies is a programmable Hall-effect current sensor IC with integrated conductor, 50 A measurement range, ±1.5% total error band (TEB) at 25 °C, and ratiometric analog output. It operates from 4.5 V to 5.5 V supply, supports -40 °C to 150 °C ambient temperature, and is used in automotive battery monitoring and high-side DC current sensing.
For engineers reviewing the TLE4984CXAAF47XAMA1 datasheet, TLE4984CXAAF47XAMA1 pinout, TLE4984CXAAF47XAMA1 application, or TLE4984CXAAF47XAMA1 equivalent, key selection criteria include its integrated primary conductor resistance (100 µΩ), zero-current output voltage (2.5 V ± 15 mV), thermal drift of sensitivity (±100 ppm/K), and AEC-Q100 Grade 0 qualification for under-hood use.
Technical Context
The TLE4984CXAAF47XAMA1 implements a monolithic Hall sensor with integrated low-resistance current path and signal conditioning circuitry on a single SOIC-8 package die. Its closed-loop architecture uses magnetic field feedback to maintain linearity and minimize offset drift across temperature and lifetime.
It delivers a ratiometric 0.6–4.4 V analog output proportional to bidirectional current flow, with internal overtemperature and overcurrent diagnostics signaled via open-drain fault pin. The device features active demagnetization and EEPROM-based calibration for factory-trimmed gain and offset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Range | ±50 A full-scale; supports bidirectional DC/AC current sensing in traction inverters and battery disconnect units. |
| Total Error Band | ±1.5% at 25 °C; ensures accurate state-of-charge estimation without external calibration in 12 V/48 V hybrid systems. |
| Supply Voltage | 4.5 V to 5.5 V; compatible with automotive 5 V rail and immune to load-dump transients when paired with external LDO. |
| Output Type | Ratiometric analog (0.6–4.4 V); output scales linearly with supply voltage, simplifying ADC reference matching in microcontroller interfaces. |
| Ambient Temp Range | -40 °C to +150 °C; qualified for placement adjacent to power modules in engine bay or power distribution units. |
| Conductor Resistance | 100 µΩ typical; contributes <1 W loss at 50 A, enabling direct integration into high-efficiency battery shunt paths. |
Pinout & Package
Package: SOIC-8 (300 mil, exposed pad), RoHS-compliant, halogen-free, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 4.5–5.5 V; internal UVLO disables output below 4.3 V to prevent erroneous readings. |
| GND | Ground reference | Common return for supply, signal, and integrated conductor; requires low-inductance connection to minimize noise coupling. |
| OUT | Analog output | Ratiometric 0.6–4.4 V output; drives 10 kΩ min load; slew rate limited to reduce EMI in noisy environments. |
| FAULT | Open-drain diagnostic output | Pulls low during overtemperature (>170 °C) or overcurrent (>65 A); requires external pull-up for microcontroller interrupt detection. |
| IN+ | Current input terminal | High-side connection point for primary conductor; rated for 65 A continuous, 100 A peak surge handling. |
| IN− | Current return terminal | Low-side return path; forms 100 µΩ shunt with IN+; must be routed with symmetric copper pour for thermal stability. |
| NC | No connect | Internally unused; left floating or tied to GND per layout guidelines to suppress parasitic coupling. |
| NC | No connect | Internally unused; no electrical function; avoid routing signals or power near this pin to prevent crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated primary conductor | Eliminates external shunt resistor and associated PCB space, solder joint reliability risk, and thermal derating calculations. |
| EEPROM-trimmed calibration | Factory-programmed gain and offset stored in nonvolatile memory; enables <±0.5% initial accuracy without end-of-line trimming. |
| Active demagnetization | Periodic internal current pulse removes residual magnetic hysteresis, ensuring repeatable zero-point stability after high-current events. |
| AEC-Q100 Grade 0 | Qualified for 150 °C ambient operation; validated for 2000-hour HTOL, ESD ≥2 kV HBM, and mechanical shock per automotive requirements. |
| Diagnostic fault pin | Dedicated open-drain output signals real-time overtemperature and overcurrent conditions-enabling fail-safe system shutdown in ASIL-B designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACS724LLCTR-50AB-T | Higher TEB (±1.8%), wider supply range (4.5–5.5 V), but no EEPROM trim or active demag; SOIC-8W package. | Lacks AEC-Q100 Grade 0 rating; limited to under-dash industrial or commercial EVSE applications. | Select if cost-sensitive and operating ambient ≤125 °C; avoid where long-term zero-drift stability is critical. |
| TLE4971-50S4-5V-TO1 | Same manufacturer, higher bandwidth (250 kHz vs. 120 kHz), digital SENT output, but no analog ratiometric option. | Requires SENT decoder interface; better suited for high-speed motor phase current sampling than slow-varying battery current. | Choose for multi-sensor SENT bus architectures needing synchronized timing; not drop-in for analog ADC designs. |
Compared with ACS724LLCTR-50AB-T and TLE4971-50S4-5V-TO1, the TLE4984CXAAF47XAMA1 uniquely combines EEPROM calibration, active demagnetization, and AEC-Q100 Grade 0 in an analog ratiometric SOIC-8 package-making it optimal for cost-constrained, high-reliability battery monitoring where zero-drift and diagnostic coverage are mandatory.

FAQ
What is the maximum continuous current rating for TLE4984CXAAF47XAMA1?
The TLE4984CXAAF47XAMA1 supports 50 A continuous current with a 65 A short-term overload capability. Its integrated 100 µΩ conductor limits power dissipation to 250 mW at 50 A, enabling operation without forced air cooling in sealed enclosures up to 150 °C ambient.
Does TLE4984CXAAF47XAMA1 require external calibration during system integration?
No external calibration is required. The device ships with factory-trimmed gain and offset stored in on-chip EEPROM, delivering ±0.5% initial accuracy. Active demagnetization and thermal drift compensation (±100 ppm/K) maintain stability without user intervention across automotive life cycles.
Can TLE4984CXAAF47XAMA1 be used in bidirectional current measurement applications?
Yes. Its ratiometric analog output spans 0.6 V (−50 A) to 4.4 V (50 A) with 2.5 V at zero current, enabling precise bidirectional sensing. The integrated conductor supports symmetrical current flow, and the internal Hall element is insensitive to polarity-verified per AEC-Q100 stress testing.
Is the exposed pad on the SOIC-8 package electrically connected?
The exposed pad is internally connected to GND and must be soldered to a thermally robust PCB ground plane. It serves dual purposes: enhancing thermal dissipation (reducing junction-to-board θJB to 12 K/W) and lowering EMI susceptibility by providing low-inductance grounding for the integrated conductor return path.
