	Seller(陈宝玲(baobao)) Reply: 1. Overview U211B is a motor speed control circuit that outputs control signals by monitoring the phase of AC power supply. u211B A frequency/voltage converter and an amplifier are integrated internally to form a closed-loop system of speed control, which can be applied to In the speed-regulating motor that needs stable speed. In addition, u211B also integrates load limit, power detection and soft start It can realize the AC motor control system. Its characteristics are as follows: ● Low static current (≤ 3mA) ● Built-in frequency to voltage conversion circuit ● Balanced load limiting characteristics ● Optimized soft start function ● Speed monitoring and short circuit protection ● Automatic re-trigger function ● Typical value of trigger pulse 155mA ● Synchronous monitoring of voltage and current ● Built-in power monitoring module ● Packaging form: SOP16
