Product Buy Status Documents Automotive Recommended 5K Pricing MOSFET Driver Type Driver Type Configuration Peak Output Current (source/sink, A). Allegro MicroSystems, Inc. Announces a new full-bridge MOSFET controller for use with external N-channel power MOSFETs. The A4957 is designed for.

The A3922 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a full-bridge (H-bridge) arrangement and is specifically designed for ASIL automotive applications with high-power inductive loads, such as brush DC motors, solenoids and actuators. Full ISO-26262 documentation is available to assist safety critical applications to achieve ASIL-D certification. A unique charge pump regulator provides a programmable gate drive voltage for battery voltages down to 7 V and allows the A3922 to operate with a reduced gate drive, down to 5.5 V. A bootstrap capacitor is used to provide the above-battery supply voltage required for N-channel MOSFETs.

The full bridge can be controlled by independent logic level inputs or through the SPI-compatible serial interface. The external power MOSFETs are protected from shoot-through by programmable dead time. Integrated diagnostics provide indication of multiple internal faults, system faults, and power bridge faults, and can be configured to protect the power MOSFETs under most short-circuit conditions.

For safety-critical systems, the integrated diagnostic operation can be verified under control of the serial interface. In addition to providing full access to the bridge control, the serial interface is also used to alter programmable settings such as dead time, VDS threshold, and fault blank time. Detailed diagnostic information can be read through the serial interface. The A3922 is supplied in a 28-pin eTSSOP (suffix ‘LP’). This package is available in lead (Pb) free versions, with 100% matte-tin leadframe plating (suffix –T).
