Product details
Overview
LPY4150AL from STMicroelectronics is a dual-axis analog MEMS gyroscope measuring angular rate along pitch and yaw axes, with ±1500 dps full-scale range, 140 Hz bandwidth, 0.67 mV/dps amplified sensitivity, and operation from 2.7 V to 3.6 V across –40 °C to +85 °C - deployed in motion-sensing gaming controllers and industrial robotics interfaces.
For engineers reviewing the LPY4150AL datasheet, LPY4150AL pinout, LPY4150AL application, or LPY4150AL equivalent, this page delivers verified electrical behavior, axis-specific analog output routing (OUTX/OUTZ and 4xOUTX/4xOUTZ), embedded self-test and sleep-mode control logic, and LGA-28 package mechanical integration guidance.
Technical Context
The LPY4150AL integrates a single micromachined oscillating mass operating on the Coriolis principle, coupled with a CMOS interface IC that conditions and outputs analog voltage signals proportional to angular rate. Its sensing element is fabricated using ST's mature plastic LGA accelerometer process, ensuring high production consistency and reliability.
It features two independent analog output paths per axis: non-amplified (OUTX/OUTZ) and 4× amplified (4xOUTX/4xOUTZ), each with dedicated low-pass filtering. The device includes an internal PLL for driving/sensing synchronization, requiring external RC components on VCONT and FILTVDD pins to configure loop dynamics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full Scale Range | ±1500 dps (amplified outputs); enables high-dynamic-range motion capture without signal clipping in fast-rotation scenarios |
| Bandwidth | 140 Hz (-3 dB); supports real-time response for human-motion tracking and robotic joint control loops |
| Sensitivity (4xOUT) | 0.67 mV/dps; provides 1.5 mV resolution per 2.24 dps at 3.3 V supply, simplifying ADC interface design |
| Zero-Rate Level | 1.5 V (ratiometrically stable); establishes fixed DC reference for differential measurement and offset calibration |
| Supply Current (Normal) | 6.8 mA at 3 V; enables battery-powered handheld devices with >100-hour runtime on 2000 mAh cells |
| Operating Temp | –40 °C to +85 °C; validated for industrial enclosures and automotive cabin environments without derating |
| Self-Test Output Δ | 250 mV typical shift; allows in-system verification of mechanical integrity and signal chain continuity without external rotation |
Pinout & Package
The LPY4150AL is housed in a 4 mm × 5 mm × 1 mm plastic land grid array (LGA-28) package, optimized for compact PCB layout and high-volume reflow assembly. Its bottom-side exposed pad improves thermal dissipation and mechanical anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 20 | OUTZ / OUTX | Non-amplified analog angular-rate outputs (Z and X axes); require external amplification or direct ADC sampling with ≥12-bit resolution |
| 5, 16 | 4xIN Z / 4xIN X | Inputs to internal 4× gain amplifiers; must be tied to Vref (1.5 V) when non-amplified outputs are used |
| 7, 14 | 4xOUTZ / 4xOUTX | Buffered, low-impedance amplified outputs; enable direct connection to standard op-amp stages or SAR ADCs |
| 9, 19 | Vdd | Main power supply (2.7–3.6 V); requires local 100 nF + 10 µF decoupling per supply pin |
| 22 | Vref | Stable 1.5 V internal reference; used for biasing amplifier inputs and as ADC reference in ratiometric systems |
| 24 | HP | High-pass filter reset control; active-high signal clears external HPF drift during power-up or overload recovery |
| 26 | GND | 0 V return path; must be connected to solid ground plane beneath LGA footprint for noise immunity |
| 27 | ST | Self-test activation input; logic high applies electrostatic force to verify mechanical response and signal chain integrity |
| 28 | SLEEP/PD | Combined sleep/power-down mode control; logic high enables ultra-low-power state (1–5 µA) for intermittent sensing |
Key Features
| Feature | Design Value |
|---|---|
| Dual-axis analog output architecture | Independent pitch/yaw channels with both amplified (4×) and raw outputs - eliminates need for external gain stages in most UI applications |
| Embedded self-test | On-chip electrostatic actuation verifies sensor mass mobility and analog signal chain functionality without mechanical stimulus or external equipment |
| Configurable power modes | Three distinct states - normal (6.8 mA), sleep (2.1 mA), and power-down (1–5 µA) - support adaptive power management in battery-constrained systems |
| Integrated low-pass filtering | Fixed 140 Hz cutoff reduces aliasing risk before ADC sampling; optional external LPF adds further anti-aliasing flexibility |
| High shock survivability | Rated for 3000 g (0.5 ms) and 10,000 g (0.1 ms) pulses - suitable for handheld devices subject to drop impact and vibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-axis analog gyroscope applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXRS649 | Single-axis, digital SPI output; higher noise floor (0.015 °/s/√Hz); requires external ADC and clock source | Lacks native dual-axis integration; demands additional MCU resources for axis fusion and timing coordination | Prefer when digital interface, higher shock rating (20,000 g), or extended temperature range (–40 °C to +105 °C) is mandatory |
| LPY4150AH | Same die, but calibrated for ±500 dps full scale; 2.0 mV/dps sensitivity; identical pinout and package | Better resolution for low-speed motion (e.g., structural monitoring), but saturates above 500 dps | Select when application requires finer angular resolution below 500 dps and can tolerate reduced dynamic range |
Compared with ADXRS649 and LPY4150AH, the LPY4150AL uniquely balances dual-axis analog output, ±1500 dps range, and ultra-low-power sleep mode - making it optimal for cost-sensitive, battery-operated motion UIs where analog simplicity and wide dynamic range are prioritized.

FAQ
What is the function of the HP pin on the LPY4150AL?
The HP (High-Pass Filter Reset) pin is an active-high control input that resets external high-pass filters connected to the analog outputs. When driven high, it clears DC drift accumulation in external AC-coupled signal chains - especially useful after power-up or during rapid angular overloads. It does not affect internal circuitry or zero-rate level calibration.
How do I configure the LPY4150AL for sleep mode versus power-down mode?
Sleep mode (2.1 mA) is activated by pulling both ST and SLEEP/PD pins high; power-down mode (1–5 µA) requires ST = low and SLEEP/PD = high. Normal operation uses both pins low. These configurations are defined in Table 6 of the datasheet and do not require clock or register writes - only static logic levels on dedicated pins.
Can the LPY4150AL be used without external low-pass filtering?
Yes - its internal low-pass filter provides a fixed 140 Hz cutoff. However, if external LPF is omitted and 4xOUTX/4xOUTZ are used, pins 1–5 and 16–20 must be shorted respectively to route non-amplified signals into the 4× amplifiers. Failure to do so results in undefined output behavior.
What is the significance of the Vref pin, and how should it be used?
Vref provides a stable 1.5 V internal reference used for biasing the 4× amplifier inputs (pins 5 and 16) and as a precision reference for external ADCs. It must not be loaded beyond 10 µA; when unused, it should remain unconnected. Tying 4xIN pins directly to Vref ensures optimal common-mode rejection and gain accuracy.
