ASR022 noncontact TMR encoder sensors provide precise pulses indicating angular motion, and is more accurate and smaller than other non-contact encoders.
An ABZ interface allows the ASR022 to replace legacy optical encoders.
The sensor combines precise, low-power Tunneling Magnetoresistance (TMR) sensing elements with sophisticated digital signal processing.
The sensor is factory calibrated, with coefficients stored in internal memory.
The ASR022 is designed for harsh industrial or automotive environments with ESD protection, and full −40 °C to 125 °C operating temperature range.
IL6xxCMTI-Series isolators are
optimized for driving MOSFETs either directly or with an
external gate driver.
Resistors set the input current, and five milliamps guarantees
switching. The inputs can be configured as non-inverting or
inverting.
CMTI-grade isolators are 100% tested to ensure each part has
at least 200 kV/µs minimum Common-Mode Transient
Immunity. Simple external deglitch circuitry can extend the
CMTI to an extraordinary 350 kV/µs typical.
The parts also have an extended supply range of up to 6.6 volts
for compatibility to directly drive a range of power
MOSFETs or gate driver ICs. The parts provide full 2.5 kV isolation.

This Evaluation Board uses the 3.3-to-3.3V version of the world’s smallest isolated DC-to-DC convertor, the ILDC11-15E.
The 1.75 by 1.75 inch (45 by 45 mm) board has an ILDC11-15E plus the three required external bypass capacitors as well as LEDs to show the DC-to-DC convertor is operating. Screw terminals provide easy connections.
The ILDC11 is an ultraminiature one-quarter watt DC-to-DC convertor with 2.5 kV isolation that can be used to generate an isolated 3.3-volt bus supply from a 3.3-volt controller supply.
No additional regulation is required and there is no minimum load. Frequency hopping and shielding reduce EMI, and ferrite beads are not necessary for EMI mitigation.
This Evaluation Board is a complete isolated RS-485 / RS-422 node using the IL4622E isolated transceiver with integrated isolated DC-DC convertor.
These 2 x 3.5-inch (50 x 90 mm) boards include screw terminals and test pads. LEDs indicate DC-to-DC convertor input and output power. A 2s2p board with vias optimizes thermal performance.
The IL4622E is a high-speed, fully-isolated, full duplex differential bus transceiver with an integrated
3.3-to-3.3 volt DC-DC convertor to provide a fully-isolated 3.3 volt bus supply using the controller supply. This level of integration dramatically reduces chip count and board area.
