AS5245

Data Sheet AS5245 www.DataSheet4U.com Programmable 360º Magnetic Angle Encoder with Absolute SSI and PWM Output 1 General Description The AS5245 is a contactless magnetic angle encoder for accurate measurement up to 360º and includes two AS5145 devices in a punched stacked leadframe. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. 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 operation of the AS5245 from 3.3V or 5.0V supplies. The AS5245 is fully automotive qualified to AEC-Q100, grade 0. Two digital 12-bit absolute outputs Quadrature A/B (10- or 12-bit) and Index output signal 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 Z-axis Tolerant to magnet misalignment and air gap variations Wide temperature range: - 40ºC to +150ºC Unique Chip Identifier Fully automotive qualified to AEC-Q100, grade 0 Small package: QFN 32 LD (7x7) 3 Applications The AS5245 is ideal for applications with an angular travel range f...
