TIDA-00405 3D Printer Controller (12V) | TI.com
TIDA-00405: This design is a complete system for controlling 3-axis, single extruder-based 3D printers. The system is managed by the MSP430F5529 LaunchPad and utilizes the DRV8846 for precision stepper motor control. The CSD18534Q5A is used as a low-side switch for the hot bed heater, extruder heater, and cooling fan. The DRV5033 Hall Sensor acts as a contactless limit switch.

TIDA-00839 Magnetic Tamper Detection Using Low-Power Hall Effect Sensors Reference Design | TI.com
TIDA-00839: Magnetic tampering can paralyze any transformer in an energy measurement system, which may potentially lead to the system being unable to be powered properly or unable to correctly register the energy consumed by a load. This design implements a Class 0.2 three-phase energy measurement system that detects magnetic tampering using hall sensors. Magnetic tamper detection is enabled when running from both main and backup power sources. Methods are used to reduce the current consumption of the hall sensors to increase battery life when running from the backup power source.
