Allegro MicroSystems, LLC A3972SB-T

A3972SB-T Overview
This particular component is manufactured by Allegro MicroSystems, LLC and falls under the category of PMIC - Motor Drivers, Controllers. It is a chip that is designed specifically for controlling and driving motors. The package or case of this chip is a 24-PowerDIP (0.300, 7.62mm), which refers to its physical size and shape. It has a Moisture Sensitivity Level (MSL) of 1, indicating that it has unlimited exposure time to moisture without being damaged. The terminal finish is Matte Tin (Sn), which is a type of coating used to protect the chip's surface. This chip utilizes DMOS (Double-diffused Metal-Oxide-Semiconductor) technology, which is a type of transistor that allows for high power and voltage switching. The voltage supply range for this chip is 4.5V to 5.5V, with a fixed supply voltage of 5V. The output voltage of this chip is 50V, and it has a maximum supply current of 12mA. The step resolution of this chip is 1 to 1/64, meaning it can control the motor with very fine movements. It is also compliant with the Restriction of Hazardous Substances Directive (RoHS), which means it meets the European Union's environmental and health standards.
