PCB-Much less 3D Magnetic Sensor With Multi-Directional Measurement Functionality

A31316 is a versatile and sturdy 3D Magnetic Sensor for safety-critical techniques. It’s able to withstanding excessive temperatures and moisture with out degradation in efficiency.

Allegro has introduced A31316, a PCB-less 3D Corridor-effect place sensor that is available in a small 4 × 4 mm physique PCB-less package deal. The IC consists of the business’s quickest SENT protocol with 0.5 µs to 10 µs tick instances and features a pulse-width modulation (PWM) interface with 125 Hz to 16 kHz provider for a easy digital interface to microcontrollers. The A31316 is right for automotive security and superior driver help techniques (ADAS) functions that require excessive ranges of flexibility and dependable efficiency in harsh circumstances with excessive vibrations such because the powertrain of autos and demanding industrial functions that require linear or rotary sensing.

The A31316 sensor integrates the die and capacitors in a single package deal to deal with the necessity for high-performance, compact-position sensors which might be sturdy. The A31316 can allow versatile integration for precision contactless place sensing. It’s Allegro’s first magnetic place sensor to supply multi-direction measurement in a PCB-less SIP package deal. The A31316 gives designers with a configurable sign path and versatile linearization for end-of-line calibration to optimize measurement accuracy.

“Automobiles have gotten extra advanced with every passing yr, and the variety of sensors wanted in fashionable security and ADAS functions is growing quickly. System designers are searching for choices which might be each versatile and sturdy, and the A31316 meets that want,” says Scott Milne, Enterprise Line Director for Place Sensors at Allegro. “It’s an amazing choice for safety-critical functions—resembling restraint and shifter techniques, parking locks, and inhibitor switches—or for difficult functions—resembling transmissions and braking techniques, the place warmth and moisture can degrade efficiency. We’re excited to allow the subsequent era of car security techniques with this know-how.”

The A31316 integrates a Manchester interface for programming the EEPROM by the output pin, which eliminates the necessity for a separate programming interface. Furthermore, the sensor employs the business’s quickest SENT protocol with 0.5 µs to 10 µs tick instances. The A31316 is obtainable in a three-pin PCB-less SIP package deal.
