Product details
Overview
TLE4917HTSA1 from Infineon Technologies is a low-power omnipolar Hall-effect switch IC with open-drain output, designed for battery-powered on/off sensing in flip-phone clamshell detection. It operates from 2.4 V to 5.5 V, achieves ±3.5 mT typical operate points (PRG=VS), delivers 3.5 µA standby current, and features programmable output polarity via the PRG pin - enabling ultra-low-power magnetic presence detection in portable consumer electronics.
For engineers reviewing the TLE4917HTSA1 datasheet, TLE4917HTSA1 pinout, TLE4917HTSA1 application, or TLE4917HTSA1 equivalent, key selection criteria include its 50 µs operating time, 130 ms standby interval, PRG-controlled output inversion, ±2.2–±7 mT magnetic switching range, and P-TSOP6-6-2 package compatibility with space-constrained PCB layouts.
Technical Context
The TLE4917HTSA1 integrates a chopper-stabilized Hall probe, active error compensation circuitry, and a timing-controlled oscillator/sequencer that alternates between 50 µs active sensing phases and 130 ms standby latched states. Its internal bias generator and temperature-compensated threshold comparator ensure stable BOP/BRP across –40 °C to +85 °C ambient.
Output polarity is determined by the PRG pin: tied to VS yields high-Z output at zero field (default), while tied to GND inverts behavior so output goes high only under magnetic field - reducing average current in normally-fielded applications. The n-channel open-drain output sinks up to 1 mA with ≤0.4 V saturation voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.4 V to 5.5 V - supports single-cell Li-ion and dual-cell alkaline battery systems without regulation. |
| Standby Current | Typ. 3.5 µA - enables multi-year operation in always-on magnetic detection circuits. |
| Operating Time | Typ. 50 µs - defines minimum magnetic event duration detectable per cycle. |
| Standby Time | Typ. 130 ms - sets maximum latency between magnetic state changes and output update. |
| Magnetic Operate Point (PRG=VS) | ±3.5 mT (typ.) - determines minimum field strength required to trigger output transition. |
| Output Type | N-channel open-drain - requires external pull-up; compatible with 1.8 V–5.5 V logic interfaces. |
| Hysteresis | 1 mT (typ.) - prevents chatter near switching threshold under marginal field conditions. |
Pinout & Package
Packaged in P-TSOP6-6-2 (6-pin thin small-outline package, 1.6 mm × 2.9 mm × 0.95 mm), with exposed pad for thermal dissipation and mechanical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VS) | Positive supply input | Accepts 2.4–5.5 V; bypass capacitor (10 nF) required between VS and GND for noise immunity. |
| 2, 4, 5 (GND) | Ground reference | Three dedicated ground pins reduce impedance and improve ESD robustness and signal integrity. |
| 3 (Q) | Open-drain output | Sinks up to 1 mA; requires external pull-up resistor to define logic-high level. |
| 6 (PRG) | Output polarity programming input | Logic level selects default output state at B = 0 mT: VS → Q high idle; GND → Q low idle. |
Key Features
| Feature | Design Value |
|---|---|
| Omnipolar magnetic sensing | Detects both North and South pole approach - eliminates magnet orientation dependency in mechanical assemblies. |
| Chopper-stabilized Hall architecture | Actively cancels offset drift from temperature, stress, and process variation - ensures ±0.2 mT repeatability over life. |
| Programmable output polarity | PRG pin configures idle-state output to minimize system-level current draw in normally-fielded use cases. |
| Ultra-low average power | 3.5 µA standby + 50 µs active bursts yield <4 µA total average - extends battery life in intermittent-sense applications. |
| ESD robustness | ±2 kV HBM rating - withstands handling and assembly without additional protection circuitry. |
Applications
| Clamshell Lid Detection | Smart Cover Wake/Sleep |
|---|---|
Use Scenario: Detect open/closed state of flip-phone or tablet cover using embedded magnet and PCB-mounted sensor. IC Role / Device Role / Timing Role: Omnipolar Hall switch providing latched digital on/off signal synchronized to mechanical actuation. Use Value: Eliminates need for mechanical switches; 3.5 µA standby current enables years of operation on coin-cell or primary batteries. | Use Scenario: Trigger wake-from-sleep or display on/off when magnetic smart cover is attached or removed. IC Role / Device Role / Timing Role: Low-latency (50 µs sensing window), low-power magnetic presence detector interfacing directly to PMIC or SoC GPIO. Use Value: PRG pin allows inverted output to keep system in low-power state until cover removal - reducing average system current. |
| Portable Device Position Sensing | Low-Power IoT Door/Window Sensor |
Use Scenario: Monitor hinge angle or folding status in foldable phones or wearable devices with compact magnetic targets. IC Role / Device Role / Timing Role: High-stability Hall switch with ±1 mT hysteresis preventing false triggers during vibration or slow movement. Use Value: Temperature-compensated switching points maintain accuracy from –40 °C to +85 °C without calibration. | Use Scenario: Battery-operated wireless sensor node detecting door/window opening in smart home security systems. IC Role / Device Role / Timing Role: Self-timed, duty-cycled Hall switch minimizing RF transmission frequency by triggering only on state change. Use Value: 130 ms standby interval reduces wake-up overhead; open-drain output interfaces directly to microcontroller interrupt pin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar omnipolar Hall switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis US5881LUA-AAA-000-RE | Higher sensitivity (BOP ±1.5 mT), 3.3 V fixed supply, no PRG pin - output polarity fixed. | Requires tighter mechanical air gap; lacks programmable idle state for current optimization. | Preferred where minimal field strength is available and polarity inversion is unnecessary. |
| Allegro A3263LUA-T | Wider supply range (2.5–24 V), higher output sink (25 mA), no standby cycling - continuous operation. | Not suitable for ultra-low-power battery use; consumes ~3.5 mA continuously vs. 3.5 µA average. | Selected for industrial position sensing where power budget permits and higher drive capability is needed. |
Compared with US5881LUA-AAA-000-RE and A3263LUA-T, the TLE4917HTSA1 uniquely balances sub-µA average current, PRG-configurable idle state, and robust 6-pin TSOP packaging - making it optimal for space- and energy-constrained consumer portable designs.

FAQ
What is the function of the PRG pin on the TLE4917HTSA1?
The PRG pin selects the default output state at zero magnetic field: connecting PRG to VS holds Q high when B = 0 mT (standard mode), while connecting PRG to GND holds Q low at B = 0 mT (inverted mode). This enables current optimization in applications where the magnetic field is normally present - allowing the output transistor to remain off and eliminate static current draw.
Can the TLE4917HTSA1 operate from a 1.8 V supply?
No. The TLE4917HTSA1 has a minimum supply voltage of 2.4 V per its absolute ratings and operating range specifications. Operation below 2.4 V is not guaranteed and may result in undefined output behavior or failure to latch correctly during the operating phase.
Is an external bypass capacitor required for stable operation?
Yes. A 10 nF ceramic capacitor must be placed between VS and GND, as specified in the datasheet. This capacitor stabilizes the internal bias network during the 50 µs operating burst and suppresses supply transients induced by the chopper clock, ensuring repeatable magnetic switching thresholds and preventing false triggers.
Does the TLE4917HTSA1 support automotive qualification standards?
No. The datasheet explicitly states "Not suitable for automotive application." It is not AEC-Q100 qualified, lacks automotive-grade temperature range (–40 °C to +125 °C), and does not meet automotive ESD or reliability requirements. It is intended for industrial and consumer portable electronics only.
