10-bit magnetic rotary encoder integrates wake-up, power-down features

austriamicrosystems produces the AS5050 10-bit magnetic rotary encoder in a small 4x4 mm package which operates over a temperature range of -40 to +85°C.

austriamicrosystems, a manufacturer of high-performance analog ICs, has announced the AS5050 10-bit magnetic rotary encoder IC for contactless position sensing with the low power requirements and space saving design. Featuring automatic power-down and wake-up modes, the AS5050 encoder is targeted for low-power applications such as robotics and is also suited for servo motor control and as an input device for low-cost battery operated devices.

The single-chip AS5050 integrates four Hall sensor elements, a 10-bit angle encoder, a smart power management controller and an easy-to-use 3- or 4-wire SPI communications interface. Housed in a small 4x4 mm QFN-16 package, the low-power encoder is one of the smallest devices in its class. Depending on the readout rate, the current consumption is reduced to µA levels. For example, 50 µA at 10 measurements per second is typical current drain.

Only a few passive components and a magnet rotating above the chip are necessary to assemble a contactless position measurement encoder system. The AS5050 magnetic rotary encoder performs all angle calculations on chip, features on-chip automatic wake-up and power-down, and only draws current when a new measurement is requested by the host controller. The AS5050 automatically powers down as soon as a measurement is completed.

Andreas Pfingstl, product marketing manager at austriamicrosystems, stated, “Thanks to its automatic shutdown and wake-up modes, the AS5050 is the industry’s lowest power 10-bit magnetic rotary encoder available and extends the time between charges for battery powered equipment. It also offers simple hook-up to common microcontrollers with an industry-standard SPI interface.”

The AS5050 rotary encoder IC operates from a 3.3 volt power supply over an ambient operating temperature range of -40 to +85°C.
