Product details
Overview
TLE49613LHALA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for high-precision position sensing in automotive powertrain and body electronics. It operates from 3.0 V to 32 V supply, delivers ±7.5 mT magnetic switching thresholds with <0.35 µs output jitter, and functions across −40°C to +170°C - enabling direct integration into motor-driven window lifters and seat adjusters without external protection components.
For engineers reviewing the TLE49613LHALA1 datasheet, TLE49613LHALA1 pinout, TLE49613LHALA1 application, or TLE49613LHALA1 equivalent, this device supports robust index counting via pole-wheel sensing, offers reverse polarity protection (−18 V), overvoltage tolerance up to 42 V, and open-drain output with integrated overcurrent/overtemperature protection - critical for AEC-Q100-compliant automotive designs.
Technical Context
The TLE49613LHALA1 implements a spinning Hall plate architecture with chopper-stabilized amplification and dynamic offset cancellation, ensuring stable BOP/BRP thresholds over temperature. Its internal voltage regulator enables operation directly from unregulated battery rails, while the oscillator-controlled sequencer synchronizes signal processing to suppress low-frequency noise.
It features a single-pole double-throw (SPDT) latch behavior: the output remains latched high or low until the opposite magnetic polarity exceeds the release point. The open-drain Q terminal requires an external pull-up resistor and supports sink currents up to 50 mA at 170°C, with saturation voltage ≤0.4 V at 20 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 32 V - supports direct connection to automotive battery without pre-regulation; tolerates load-dump transients up to 42 V. |
| Magnetic Switching Thresholds | BOP = +7.5 mT, BRP = −7.5 mT - precise bipolar latch behavior for accurate pole-wheel edge detection in rotational sensing. |
| Output Type | Open-drain N-channel MOSFET - enables flexible pull-up configuration and wired-OR interfacing with microcontroller GPIOs. |
| Operating Temperature | −40°C to +170°C - qualified per AEC-Q100 Grade 0, suitable for under-hood and motor-adjacent placement. |
| Output Jitter | Typ. 0.35 µs - ensures deterministic timing in high-speed index counting (e.g., >10 kHz wheel rotation). |
| ESD Protection | HBM ±8 kV - eliminates need for external TVS diodes in typical PCB layouts. |
| Supply Current | 1.6 mA at 25°C - enables low-power always-on sensing in battery-supplied modules. |
Pinout & Package
Delivered in the PG-SSO-3-2 leaded surface-mount package (3-pin, 2.08 mm × 1.35 mm footprint), optimized for thermal dissipation and mechanical robustness in high-vibration environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; internal regulator powers all circuit blocks; reverse polarity protected to −18 V. |
| 2 - GND | Ground reference | Common return path for supply and output current; thermally coupled to die for accurate overtemperature shutdown. |
| 3 - Q | Open-drain output | Sinks up to 50 mA; logic-low when south pole detected (B > +7.5 mT), latches low until north pole exceeds −7.5 mT. |
Key Features
| Feature | Design Value |
|---|---|
| Active error compensation | Chopper-stabilized amplifier and spinning Hall probe reduce offset drift to <0.1 mT/°C - maintains threshold accuracy across full temperature range. |
| Overvoltage capability | Withstands 42 V transients without external resistor - simplifies design for 12 V/24 V systems exposed to load-dump events. |
| Integrated protection | Auto-recovering overcurrent and overtemperature shutdown - prevents latch failure during motor stall or short-circuit conditions. |
| High ESD performance | HBM ±8 kV rating - eliminates need for discrete ESD protection on board, reducing BOM count and layout area. |
| Leaded PG-SSO-3-2 package | RoHS-compliant SnPb finish with 0.95 mm pitch - supports wave soldering and visual solder-joint inspection in automotive manufacturing. |
Applications
| Power Window Lift Control | Seat Position Sensing |
|---|---|
|
Use Scenario: Detecting gear tooth or pole-wheel rotation during window glass ascent/descent to prevent pinch detection timeout and ensure smooth stop positioning. IC Role / Device Role / Timing Role: Bipolar latch providing edge-triggered index pulses synchronized to motor shaft rotation; output jitter <0.35 µs ensures sub-millimeter positional resolution at 100 rpm. Use Value: Enables reliable anti-pinch compliance without additional optical encoders or microcontroller-based filtering - reduces system cost and firmware complexity. |
Use Scenario: Monitoring seat track position via embedded pole wheel to support memory seat recall and automatic adjustment. IC Role / Device Role / Timing Role: Latching output toggles on each pole transition; stable ±7.5 mT thresholds maintain consistent pulse width across −40°C to +170°C ambient extremes. Use Value: Eliminates calibration drift over vehicle lifetime - avoids relearning cycles and improves user experience in varying climate conditions. |
| Engine Camshaft Position | Brake Caliper Actuator Feedback |
|
Use Scenario: Detecting cam lobe passage for variable valve timing (VVT) control in gasoline engines operating under hood temperatures up to 150°C. IC Role / Device Role / Timing Role: High-temperature latch delivering deterministic rising/falling edges to ECU; internal voltage regulator sustains operation during cranking (6.5 V min). Use Value: Maintains timing integrity during cold-start and transient load conditions - critical for emissions compliance and combustion efficiency. |
Use Scenario: Verifying piston extension/retraction in electric parking brake (EPB) calipers where space constraints limit sensor size and thermal management. IC Role / Device Role / Timing Role: Open-drain output interfaces directly with 5 V MCU GPIO; 50 mA sink capability drives indicator LED or status line without buffer. Use Value: Reduces component count and PCB area versus optocoupler-based feedback - accelerates EPB module qualification and lowers assembly cost. |
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-RE | Wider BOP/BRP spread (±10 mT); no integrated overvoltage protection beyond 28 V; HBM ESD = ±4 kV. | Lacks 42 V load-dump tolerance - requires external TVS in 24 V commercial vehicles; lower temperature max (+150°C). | Select when cost sensitivity outweighs AEC-Q100 requirement and thermal margin is sufficient. |
| Allegro A1220LUA-T | Lower supply range (4.5–24 V); BOP/BRP = ±9 mT; no reverse polarity protection; jitter = 1.2 µs. | Not qualified to AEC-Q100; unsuitable for direct battery connection in 12 V start-stop systems due to undervoltage cutoff. | Use only in non-automotive industrial motion control where extended voltage and temperature ranges are not required. |
Compared with US1881EUA-ABA-000-RE and A1220LUA-T, the TLE49613LHALA1 provides superior thermal margin (+170°C), guaranteed 42 V transient immunity, and tighter jitter - making it the only choice for safety-critical, high-reliability automotive latch sensing where functional stability must be maintained across full vehicle lifecycle conditions.

FAQ
What is the maximum continuous sink current of the TLE49613LHALA1 output at 170°C?
The TLE49613LHALA1 guarantees a minimum output sink current of 50 mA at 170°C, with saturation voltage ≤0.4 V at that load. This is validated per datasheet Figure 21 and supports direct driving of LEDs or logic-level inputs without external buffers in high-temperature zones like engine compartments.
Does the TLE49613LHALA1 require an external pull-up resistor?
Yes - the Q pin is an open-drain output and requires an external pull-up resistor to VDD or another logic rail. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time requirements and bus capacitance; no internal pull-up is integrated.
Can the TLE49613LHALA1 operate from a 5 V regulated supply?
Yes - the device operates across 3.0 V to 32 V, so a 5 V regulated supply is fully supported. At 5 V, supply current drops to ~1.4 mA (per Figure 20), and output rise/fall times improve due to reduced RC time constant with typical pull-up values.
Is the PG-SSO-3-2 package RoHS-compliant and lead-free?
No - the PG-SSO-3-2 package for TLE49613LHALA1 uses a SnPb (tin-lead) finish per Infineon's automotive qualification requirements. It is exempt from RoHS lead restrictions under Annex III (Category 7a) for high-reliability automotive applications requiring proven solder joint reliability.
