GENERAL DESCRIPTION
To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879º = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AS5145 to operate at either 3.3V or 5V supplies. Three incremental outputs Quadrature A/B (10 or 12 bit) and Index output signal (preprogrammed versions available AS5145A for 10 bit and AS5145B for 12 bit) User programmable zero position Failure detection mode for magnet placement, monitoring, and loss of power supply Red-Yellow-Green indicators display placement of magnet in Zaxis Serial read-out of multiple interconnected AS5145 devices using Daisy Chain mode Tolerant to magnet misalignment and gap variations Wide temperature range: - 40ºC to +150ºC...
