Product details
Overview
TLE49615MXTMA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for precision position and speed sensing in automotive powertrain and chassis systems. It features 3.0–32 V supply operation, ±15 mT magnetic thresholds (BOP/BRP), open-drain output, -40°C to +170°C operating temperature, and AEC-Q100 qualification - enabling direct integration into engine cam/crank sensing and transmission gear tooth detection circuits.
For engineers reviewing the TLE49615MXTMA1 datasheet, TLE49615MXTMA1 pinout, TLE49615MXTMA1 application, or TLE49615MXTMA1 equivalent, key selection criteria include magnetic threshold stability over temperature, load-dump immunity up to 42 V, reverse polarity protection (-18 V), low jitter (0.35 µs typ.), and PG-SOT23-3-15 package compatibility with high-vibration automotive PCB layouts.
Technical Context
The TLE49615MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, and comparator with hysteresis to deliver precise latching behavior under varying thermal and electromagnetic conditions. Its internal voltage regulator enables stable operation across 3.0–32 V supply, while active error compensation maintains ±0.5 mT threshold drift over -40°C to +170°C.
Functional block includes oscillator-driven sequencing, overtemperature/overcurrent protection circuitry, and open-drain output stage capable of sinking ≥20 mA at Vsat ≤ 0.4 V. The device exhibits no external component dependency for basic operation - only a pull-up resistor required per Figure 7 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 32 V - supports direct connection to unregulated automotive battery rails including cold-crank (3.0 V) and load-dump transients (42 V peak, no external resistor needed). |
| Magnetic Thresholds | BOP = +15 mT, BRP = -15 mT - symmetric bipolar latch behavior enables reliable pole-wheel edge detection with 30 mT hysteresis for noise immunity. |
| Output Type | Open-drain N-channel MOSFET - allows flexible pull-up to any voltage ≤32 V and supports wired-OR configurations in multi-sensor systems. |
| Temperature Range | -40°C to +170°C - qualified for under-hood applications including engine control modules and transmission control units. |
| Jitter (typ.) | 0.35 µs - ensures sub-degree timing accuracy in crankshaft position measurement at 10,000 RPM. |
| ESD Protection | ±4 kV HBM - eliminates need for external TVS diodes in standard ISO 10605-compliant harness environments. |
| Power-On Time | tPON = 30 µs (max) - enables fast system wake-up after ignition-on without missing initial cam/crank edges. |
Pinout & Package
Package: PG-SOT23-3-15 - thermally enhanced SMD package with exposed die pad, optimized for high-temperature automotive mounting and reflow compatibility (JEDEC J-STD-020 moisture sensitivity level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; internal regulator powers all analog/digital blocks; reverse polarity protection (-18 V) prevents damage during battery misconnection. |
| 2 - Q | Open-drain output | Sinks current when magnetic field exceeds BOP; high-impedance state when field below BRP; requires external pull-up for logic-level interface. |
| 3 - GND | Ground reference | Common return path for supply and output; tied internally to exposed thermal pad for improved heat dissipation in high-temp operation. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage capability | Withstands 42 V transients without external clamping - eliminates series resistor and reduces BOM count in 12 V/24 V vehicle platforms. |
| Active error compensation | Chopper-stabilized architecture reduces offset drift to <0.5 mT over full temperature range - enables single-threshold calibration across production life. |
| Low-jitter timing | 0.35 µs typical output delay variation - supports crankshaft position resolution better than 0.1° mechanical at 8,000 RPM. |
| Integrated protection | On-chip overtemperature shutdown and output short-circuit current limiting - prevents latch failure during ESD events or wiring faults. |
| Small footprint | PG-SOT23-3-15 (2.9 × 1.3 × 1.0 mm) - fits tight spaces near rotating components and enables high-density sensor placement on compact ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar Hall latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis US1881EUA-ABA-000-REEL | Lower supply range (2.5–24 V); ±18 mT thresholds; no integrated overvoltage protection beyond 28 V. | Limited to 12 V systems; unsuitable for 24 V commercial vehicles or load-dump scenarios without external clamping. | Select when cost sensitivity outweighs 42 V transient immunity and extended temperature range. |
| Allegro A1220LUA-T | Wider BOP/BRP spread (±25 mT); higher jitter (1.2 µs typ.); rated only to +150°C. | Reduced positional accuracy at high RPM; not qualified for under-hood locations exceeding 150°C ambient. | Choose for non-automotive industrial encoders where thermal margin and timing precision are relaxed. |
Compared with US1881EUA-ABA-000-REEL and A1220LUA-T, TLE49615MXTMA1 delivers superior thermal robustness, tighter magnetic tolerance, lower jitter, and native 42 V transient handling - making it the only option qualified for direct integration into AEC-Q100-compliant powertrain control modules.

FAQ
What is the maximum continuous supply voltage the TLE49615MXTMA1 can withstand?
The TLE49615MXTMA1 operates continuously from 3.0 V to 32 V. It withstands transient overvoltages up to 42 V (e.g., automotive load-dump events) without external protection components, as confirmed in Section 3.2 of the datasheet Revision 1.2.
Does the TLE49615MXTMA1 require an external pull-up resistor?
Yes - the device features an open-drain output (Pin 2, Q) and requires an external pull-up resistor to define the high logic level. Typical values range from 1 kΩ to 10 kΩ, depending on rise time and bus voltage; no other passive components are needed for basic operation.
How does the TLE49615MXTMA1 handle reverse battery connection?
The device incorporates integrated reverse polarity protection down to -18 V, allowing safe operation even if the battery is connected backward during service or assembly - eliminating the need for external series diodes or protection FETs in the supply path.
Is the TLE49615MXTMA1 qualified for ASIL-B functional safety applications?
While not ASIL-B certified standalone, the TLE49615MXTMA1 is AEC-Q100 Grade 0 qualified (-40°C to +175°C), features built-in diagnostics (overtemperature/overcurrent shutdown), and supports system-level ASIL-B architectures when combined with appropriate MCU monitoring - as documented in Infineon's TLE496x Functional Safety Manual.
