Product details
Overview
TLE4972AE35S5XUMA1 from Infineon is a high-precision, coreless, monolithic Hall-effect current sensor for automotive-grade DC/AC measurement with ±31 mT full-scale range, 62 mV/mT sensitivity, and dual independent over-current detection outputs (OCD1/OCD2) with 0.7 µs response time. It operates from 3.1–3.5 V supply, supports semi-differential analog output mode, and is ASIL B compliant per ISO 26262 for battery main switches and on-board chargers.
For engineers reviewing the TLE4972AE35S5XUMA1 datasheet, TLE4972AE35S5XUMA1 pinout, TLE4972AE35S5XUMA1 application, or TLE4972AE35S5XUMA1 equivalent, key selection criteria include differential stray-field immunity, in-situ calibration capability, EEPROM-configurable OCD thresholds (BTHR1.2 = 1.39×FS, BTHR2.4 = 0.82×FS), and PG-VSON-6 package integration for low insertion resistance in high-voltage traction inverters.
Technical Context
The TLE4972AE35S5XUMA1 implements a differential Hall probe architecture that measures magnetic field gradients induced by primary-side current, eliminating saturation and hysteresis inherent in flux-concentrating sensors. Its digitally assisted analog signal path integrates real-time temperature and stress compensation via on-chip EEPROM-trimmed parameters.
Two open-drain OCD pins provide hardware-level fault signaling with independently programmable thresholds and zero deglitch filtering (OCD1gl_mul = OCD2gl_mul = 0). The semi-differential output mode fixes VREF as internal reference output (VOQbid_1 = VDD/2) while AOUT delivers single-ended bidirectional current data with ratiometric sensitivity relative to VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full Scale Range | ±31 mT - enables accurate measurement of up to 2,000 A primary current without magnetic core saturation |
| Sensitivity | 62 mV/mT - provides 1.922 V output swing at full scale in semi-differential mode with VDD = 3.3 V |
| OCD Response Time | 0.7 µs - allows hardware-triggered shutdown before power-stage damage in IGBT/MOSFET protection circuits |

Pinout & Package
PG-VSON-6 package with 0.65 mm pitch, 3.0 × 3.0 mm body, and thermally enhanced exposed pad (EP) requiring GND connection for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | 3.1–3.5 V power rail; powers analog front-end, digital compensation unit, and OCD drivers |
| GND | Ground reference | Analog/digital common return; EP must be soldered to GND plane for thermal and noise control |

| OCD2 | Over-current detection 2 | Open-drain output asserting low when |IPN| > 0.82×FS; independent threshold, same timing spec as OCD1 |
Key Features
| Feature | Design Value |
|---|---|
| Differential Hall sensing | Rejects external stray fields >95% compared to single-probe architectures, enabling operation near motors/inverters |
| In-situ calibration support | Allows system-level end-of-line (EOL) offset/sensitivity trimming via EEPROM programming on OCD2 pin at 20.6 V |
| Configurable OCD thresholds | BTHR1.2 and BTHR2.4 stored in EEPROM enable asymmetric trip levels for fast fault grading (e.g., warning vs. shutdown) |
| Semi-differential output | VREF output fixed at VDD/2 eliminates need for external reference; AOUT delivers full-rail bidirectional signal with minimal board area |
| Coreless architecture | Zero hysteresis, no saturation, and <1 ppm/°C lifetime drift-critical for battery state-of-charge accuracy over 15-year vehicle life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar coreless current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACS724LLCTR-30AB-T | Integrated magnetic concentrator; ±30 A FS; 132 mV/A sensitivity; no EEPROM configuration; single OCD output | Lacks ASIL compliance and dual-threshold OCD; suitable for non-safety-critical 12 V auxiliary systems only | Select if cost-sensitive, low-volume 12 V applications require basic overload detection without functional safety certification |
| TMCS1108A4U | Isolated Hall-effect sensor; ±50 A FS; 400 mV/A; internal 2.5 V reference; single OCD; no in-situ calibration | No ASIL rating; lower bandwidth (1.5 MHz vs. TLE4972's >2 MHz); limited to ≤125 °C ambient | Choose for industrial SMPS where extended temperature range and automotive qualification are not required |
Compared with ACS724LLCTR-30AB-T and TMCS1108A4U, the TLE4972AE35S5XUMA1 uniquely combines ASIL B certification, dual independent OCD outputs with sub-microsecond latency, EEPROM-based in-system calibration, and differential stray-field rejection-making it the only option qualified for battery disconnect and traction inverter protection in ISO 26262-compliant EV platforms.

FAQ
What is the purpose of the VREF pin in semi-differential mode?
In semi-differential mode, VREF functions as an output-not an input-providing a stable internal reference voltage (VOQbid_1 = VDD/2) to establish the quiescent point for AOUT. This eliminates external reference components and ensures ratiometric tracking between supply and output offset, critical for accuracy across automotive voltage transients.
How is over-current detection configured on OCD1 and OCD2?
OCD1 and OCD2 thresholds are factory-programmed into EEPROM as BTHR1.2 = 1.39×FS and BTHR2.4 = 0.82×FS, respectively. These values can be reconfigured using 20.6 V programming voltage applied to OCD2, enabling customer-specific trip points for graded fault responses without changing hardware.
Does the TLE4972AE35S5XUMA1 require external magnetic shielding?
No external shielding is required. Its differential Hall probe architecture inherently suppresses uniform external magnetic fields by >40 dB, validated per ISO 11452-8. This allows direct mounting adjacent to high-current busbars, motors, or transformers without performance degradation.
What is the role of the exposed pad (EP) in the PG-VSON-6 package?
The exposed pad (EP) must be soldered to a dedicated GND copper pour on the PCB to serve three functions: (1) thermal conduction to dissipate up to 1.2 W junction-to-board, (2) low-impedance GND return for analog and OCD signals, and (3) EMI reduction by minimizing loop area for high-frequency noise currents.
