Product details

Overview

TLE4988CXTFM28HAMA1 from Infineon is a programmable active Hall-effect camshaft position sensor with True Power On (TPO) capability from zero speed, designed for automotive engine management systems. It delivers digital open-drain output, supports ferrite magnet targets, features end-of-line programmable switching thresholds (k-factor 25–75%), integrated 220 nF/1.8 nF decoupling capacitors, and operates across −40 °C to +175 °C junction temperature.

For engineers reviewing the TLE4988CXTFM28HAMA1 datasheet, TLE4988CXTFM28HAMA1 pinout, TLE4988CXTFM28HAMA1 application in camshaft timing, or TLE4988CXTFM28HAMA1 equivalent for AEC-Q100-compliant engine control units, this page provides verified functional specifications, validated pin-level interface behavior, magnetic field range (−15 mT to +45 mT), TPO calibration options, and real-world EMC design guidance including R_Supply and R_Load recommendations.

Technical Context

The TLE4988CXTFM28HAMA1 implements a mono-cell chopped-Hall sensing core with on-chip temperature compensation and EEPROM-programmable algorithms for phase-accurate camshaft signal generation. Its digital core performs real-time offset calculation, min/max detection, hysteresis selection (1.4–6.8 mT), and μBreak-enabled vibration suppression.

It integrates three independent voltage regulators (for analog Hall elements, bandgap reference, and digital/EEPROM domains), supports selectable output fall times (2.4–10.1 µs at 12 V; 1–5 µs at 5 V), and embeds pre-programmed temperature coefficient (−2000 ppm/K) optimized for ferrite magnets - enabling stable switching thresholds across wide thermal gradients without external calibration.

Key Specifications

Parameter	Value and Actual Design Meaning

IC Role / Device Role / Timing Role: Primary camshaft timing sensor delivering synchronized digital edges aligned to physical cam events with <19 µs magnetic-to-output delay.

Use Value: Enables precise ignition/fuel injection timing via TPO and programmable delay; integrated capacitors reduce PCB footprint and improve EMC pass rate in noisy engine bays.

Use Scenario: Measuring rotational speed of rotating shafts in industrial gearmotors, conveyors, and hydraulic pumps where zero-speed detection is required.

IC Role / Device Role / Timing Role: Standalone speed-to-digital converter interfacing directly with PLC inputs or microcontroller GPIOs using open-drain logic.

Use Value: Eliminates need for external conditioning circuitry; −40 °C to +175 °C operation supports harsh environments; TIM mounting simplifies mechanical integration.

Automotive Crank-Cam Synchronization

Off-Highway Equipment Timing

Use Scenario: Coordinating crankshaft and camshaft signals in dual-sensor engine architectures to detect misfire, skipped teeth, or timing belt slippage.

IC Role / Device Role / Timing Role: Secondary timing reference providing absolute cam phase information to complement crank sensor data for fault diagnostics.

Use Value: Programmable hysteresis and k-factor allow field recalibration after magnet aging; EEPROM storage retains settings across power cycles.

Use Scenario: Monitoring cam-driven hydraulic valve actuation in agricultural tractors, construction excavators, and mining equipment.

IC Role / Device Role / Timing Role: Robust position feedback element operating in high-vibration, high-temperature, and ESD-prone environments.

Use Value: AEC-Q100 qualification ensures reliability; integrated 6 kV HBM ESD immunity protects against handling and system-level transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar camshaft position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4988CXTNM28HAMA1	Pre-trimmed for NdFeB magnets (TC = −1200 ppm/K); wider magnetic range (−31.1 to +134.6 mT)	Required when using neodymium magnets; higher sensitivity but reduced thermal stability vs. ferrite	Select for higher signal amplitude targets where tighter air gaps and lower temperature drift are prioritized
TLE4988CXTSM28HAMA1	Pre-trimmed for SmCo magnets (TC = −600 ppm/K); narrowest hysteresis option (1.4 mT only)	Used in precision cam phasing systems requiring minimal switching uncertainty at elevated temperatures	Choose for high-accuracy phase measurement in turbocharged engines with SmCo target wheels

Compared with TLE4988CXTFM28HAMA1, the XTNM28 variant offers broader magnetic coverage but less thermal stability, while the XTSM28 provides superior temperature tracking at the cost of reduced hysteresis flexibility - making the XTFM28 optimal for cost-sensitive, ferrite-based mass-market ICE platforms.

FAQ

What is the purpose of the integrated 220 nF and 1.8 nF capacitors?

The 220 nF capacitor between VS and GND suppresses high-frequency supply noise and improves EMC robustness in automotive 12 V systems. The 1.8 nF capacitor between VOUT and GND filters output transients and stabilizes the open-drain switching edge. Both are embedded in the PG-SSO-3-52 package, eliminating external components and reducing PCB area and assembly cost.

Can the TLE4988CXTFM28HAMA1 operate without an external supply resistor?

Yes - it operates from 4–24 V without a series supply resistor. However, Infineon recommends adding a 47–100 Ω resistor (R_Supply) on the VS line in 12 V applications to enhance EMC performance and limit inrush current during hot-plug events, especially in noisy engine bay environments.

How is True Power On (TPO) calibrated for ferrite magnet targets?

TPO calibration is performed end-of-line using the digital diagnosis interface. The device measures ambient magnetic offset during power-up and stores adaptive correction values in EEPROM. For ferrite targets, the programmable TPO range is −15 to +45 mT, and the pre-programmed −2000 ppm/K temperature coefficient ensures consistent zero-speed switching across −40 °C to +175 °C.

What does "Twist Insensitive Mounting (TIM)" mean mechanically?

TIM refers to the sensor's internal mechanical and magnetic design that renders its output insensitive to ±15° rotational misalignment around the mounting axis. This eliminates the need for precise angular orientation during installation in engine blocks or gear housings, reducing assembly time and calibration complexity in high-volume manufacturing.
