• Includes built-in current sensing capabilities eliminating the need for external sense resistors
• Features programmable gate drive settings to reduce electromagnetic interference and transient noise

Applications

• Window and door actuators
• Electric vehicle charger locks
• Electronic parking brakes
• Foldable rearview mirrors
• Brushed DC motor control in battery-powered building automation and robotics

Procurement Notes

Verify the NRND status before integration, as this designation indicates the component is not recommended for new designs. Confirm RoHS compliance details through official datasheets. Ensure ESD precautions are observed during handling due to moisture sensitivity classification. Validate that the QFN-20 footprint matches the target PCB layout requirements prior to procurement.

Selection Notes

Select this component when designing systems requiring solid-state replacement for mechanical relays in space-constrained environments. It is suitable for applications needing integrated diagnostics and reduced bill of materials. Consider its 50V absolute maximum rating and low standby current consumption for battery-operated devices. Evaluate compatibility with existing microprocessor interfaces for diagnostic data retrieval.

Part Context

This part belongs to the A89506 series of full-bridge gate drivers from Allegro MicroSystems. It shares architectural similarities with the A89505 but differs in control interface options. The series aims to reduce PCB size by 36% compared to traditional 5x5mm packages while integrating advanced motor control features directly into the semiconductor solution.
