AMIS39100PNPB3RG

Power Distribution Switches, Load Drivers Overview

The AMIS39100PNPB3RG is a single-chip stepper motor driver manufactured by onsemi. It integrates a high-voltage bipolar process with advanced control logic to drive two-phase stepper motors. The device features an integrated H-bridge power stage capable of delivering continuous current up to 2.5 A per phase, with peak currents reaching higher levels depending on thermal conditions. It supports full-step, half-step, and microstepping resolutions via serial interface commands. Key internal protections include over-current shutdown, over-temperature protection, and under-voltage lockout to ensure reliable operation in automotive and industrial environments.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the exact suffix 'PNPB3RG' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the ordering part number matches the specific tape-and-reel or tube packaging requirements specified in the latest procurement documentation. Cross-reference the date code and lot traceability if required for your quality management system.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a robust, single-chip solution for bipolar stepper motors is required without external gate drivers. Consider the thermal dissipation capabilities of the TO-220FP package relative to your expected load current and ambient temperature. Verify that the supply voltage range aligns with your system's power architecture and that the serial interface timing meets your controller's speed requirements.
