Product details

Overview

TLE4988CXTSM28HAMA1 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. It delivers digital open-drain output, supports end-of-line programming of switching thresholds (k-factor 25–75%), offers selectable hysteresis (1.4–6.8 mT), and integrates on-package decoupling capacitors (220 nF / 1.8 nF) for enhanced EMC robustness in 12 V systems.

For engineers reviewing the TLE4988CXTSM28HAMA1 datasheet, TLE4988CXTSM28HAMA1 pinout, TLE4988CXTSM28HAMA1 application, or TLE4988CXTSM28HAMA1 equivalent, key selection criteria include TPO phase accuracy under vibration, magnetic field range adaptability (-31.1 to 134.6 mT depending on magnet type), temperature-compensated switching, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The TLE4988C implements a mono-cell chopped-Hall architecture with integrated analog front-end, digital core (including min/max detection, offset compensation, and hysteresis calculation), EEPROM-based configuration storage, and dual-regulator system (bandgap + Hall element supply). Its functional block includes μBreak detection for transient suppression and real-time temperature compensation using an on-die sensor.

It operates across 4–24 V supply (with optional 47–100 Ω series resistor), delivers <300 mV saturation voltage at 5 mA load, achieves 0.8–1 ms power-on time with output locked high during initialization, and supports programmable delay (0–28 µs) between magnetic edge and output transition - critical for timing-critical camshaft synchronization.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV4988CXTMA1	Same PG-SSO-3-52 package and core architecture, but lacks EEPROM-programmable k-factor and fixed hysteresis (3.5 mT)	Targeted at cost-sensitive applications where factory-trimmed thresholds suffice and field recalibration is unnecessary	Select when production volume justifies one-time calibration and reduced feature set lowers BOM cost
ATS6858LSGTN-T	Allegro two-wire differential Hall sensor; no integrated capacitors; requires external RC filter; higher sensitivity (15–120 mT range)	Optimized for low-air-gap, high-precision crankshaft sensing; not qualified for camshaft TPO phase accuracy	Choose for differential noise rejection in high-EMI diesel engines, but verify TPO startup behavior separately

Compared with TLV4988CXTMA1 and ATS6858LSGTN-T, the TLE4988CXTSM28HAMA1 uniquely combines EEPROM-based TPO calibration, multi-magnet-type TC trimming, and integrated EMC capacitors - making it the only option qualified for AEC-Q100 camshaft phase-critical applications requiring zero-rpm startup repeatability.

FAQ

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

The 220 nF capacitor between VS and GND and the 1.8 nF capacitor between VOUT and GND are embedded in the PG-SSO-3-52 lead frame to suppress high-frequency noise and improve EMC robustness. They eliminate the need for external decoupling components, reduce PCB layout complexity, and ensure stable operation in harsh automotive environments without additional filtering.

How does True Power On (TPO) functionality work at zero speed?

TPO is achieved through internal self-calibration algorithms that detect initial magnetic field offset during power-up and dynamically adjust the switching threshold before the first rotation. This allows reliable edge generation even when the camshaft is stationary, enabling immediate position acquisition at engine cranking - critical for fast-start emission strategies.

Can the TLE4988CXTSM28HAMA1 be used with different magnet types?

Yes - the part number suffix indicates magnet-specific pre-programming: "XTN" = NdFeB, "XTS" = SmCo, "XTF" = Ferrite. Each variant has a factory-trimmed temperature coefficient (-1200, -600, -2000 ppm/K respectively) and calibrated magnetic range, allowing optimal performance across diverse target wheel materials and air gaps without reconfiguration.

What is the role of the μBreak detection feature?

μBreak detection identifies and stores transient magnetic disturbances (e.g., from solenoid actuation or ESD events) to prevent false triggering. It captures short-duration field anomalies, holds them in dedicated memory, and suppresses output toggling during those intervals - enhancing reliability in electrically noisy engine compartments.
