Allegro mosfet driver complies with Asil B

Allegro Microsystems AMT49105 ISO 26262 compliant n-channel power mosfet driver

Allegro Microsystems has announced an ISO 26262 compliant n-channel power mosfet driver.

The AMT49105 is said to simplify motor systems designs and provide footprint reduction by integrating power analogue requirements.

Thanks to a robust output gate drive, this device can be used in a wide range of applications, including power applications above 1kW. Additionally, it provides the Lin transceiver, regulated microprocessor supply, phase monitors for sensorless BLDC control and other features that reduce overall power consumption. 

Allegro 2D latch ICs have vertical and planar Hall elements

Allegro Microsystems APS12625 and APS12626 sensor ICs

Allegro Microsystems has released a family of two-dimensional (2D) Hall-Effect latch ICs that have vertical and planar Hall elements.

The APS12625 and APS12626 sensor ICs help reduce system size and cost along with increasing performance and flexibility due to 2D sensing. They were developed in accordance with ISO 26262 and qualified per AEC-Q100.

Allegro two-wire Hall-effect ICs follow ISO 26262

Allegro Microsystems Hall-effect switch ICs

Allegro Microsystems has released a family of two-wire vertical Hall-effect switch ICs with advanced diagnostics. The A1130, A1131 and A1132 have been developed in accordance with ISO 26262.

These devices have integrated continuous diagnostic features and a safe output state that supports a functional safety level of Asil B. They have a two-wire current output interface that facilitates open and short diagnosis along with signal path verification from input to output.
