• Hall sensors optimized for 2.00 mm pole width (Master track)
• Differential scanning for external magnetic field suppression
• BiSS/SSI and SPI serial interfaces for simultaneous use
• I²C master/slave interface for configuration and diagnostic data
• FlexCount® for programmable ABZ output resolution

• Real-time interpolation with up to 65536 increments per input period
• Multiple interfaces: BiSS, SPI, I2C, ABZ, UVW, PWM
• Outstanding signal conditioning accuracy
• Vector-tracking interpolation for ultra-low latency
• Correction of signal distortion per input period
• Digital position noise filter for outstanding AB jitter
• 32-bit period counting with up to 500 kHz
• MCU connection via SPI or I²C
• BiSS access to I²C devices and memory
• RS-422 quadrature drivers and BiSS transceiver for easy cabling
• Space-saving and cost-effective
• GUI-supported self-calibration for easy commissioning
• 3.3 V or 5 V operation at –40 °C to 125 °C
• Drop-in upgrade of iC-NQx applications by 20-pin TSSOP

The iC-Gi22 dual-channel inductive sensor IC with sin/cos and interpolated SSI data output is used for magnetic off-axis position sensing using a simple metal target. The device enables absolute angle detection over the entire mechanical revolution by sampling two separate channels (master plus slave). The demodulated receiver signals feed the external processor, i.e. a suitable nterpolation device such as the iC-MNF, iC-TW29, iC-NQE, and an MCU with ADCs, to determine the position with higher resolution.

Features:

• Adjustable transmitter with coil driver (2-5 MHz, up to 20 mA)
• Two independent receiver channels with demodulation and line driver (1 Vdiff @ 100 Ω)
• High level output with selectable center voltage
• Adjustable coarse (x1...10) and fine gain (x1...20)
• Precision offset correction (via 11 bits up to 200 mV)
• Automatic gain control (per channel)
• Sin/cos interpolation with 8-bit resolution (1 channel)
• Angle output via SSI with error and warning
• I2C multi-master for self-configuration from external EEPROM
• I2C slave interface to the system (MCU)
• Operation monitoring with alarm masking: signal loss, I/O short circuit, RAM CRC
• Signal frequency up to 50 kHz (allows for 90000 rpm minimum)
• Power supply from 3.3 V to 5 V, approx. 15 mA
• Space-saving 32-pin QFN with 5x5 mm
