Description

  • BU90002GWZEVK-101, Evaluation Kit for featuring BU90002GWZEVK, synchronous buck DC/DC converter. While accepting a power supply of 4.0-5.5V, an output of 3.3V can be produced. The IC has internal 250 m-Ohm high-side P-channel MOSFET and 220 m-Ohm low-side N-channel MOSFET and a synchronization frequency range of 5.4MHz to 6.6MHz. A fixed Soft Start circuit prevents in-rush current during startup along with UVLO (low voltage error prevention circuit) and TSD (thermal shut-down detection) protection circuits. An EN pin allows for simple ON/OFF control of the IC to reduce standby current consumption. A MODE pin allows the user to select forced PWM (Pulse Width Modulation) mode or PFM(Pulse Frequency Modulation) and PWM auto change mode utilized power save operation at light load current

High-precision LiDAR and motor drive solutions applied to robot 3D perception

For a robot to achieve autonomous movement, it requires 3D perception capabilities, which involve utilizing various sensors to continuously understand the robot's position in space. Among these sensors, LiDAR (Light Detection and Ranging) is highly regarded for its ability to provide high-precision position sensing. Additionally, robots also rely on motor drive systems to execute precise movements of their own body or limbs. This article will introduce the development of LiDAR technology and the LiDAR and motor drive solutions offered by ROHM.
