TB67H450FNG/AFNG Printing machine,POS machine scheme and electric water valve control scheme
1,Printer POS scheme
In recent years, with the sustained and rapid growth of China's economy, the continuous promotion of electronic information management such as the "Three Gold Project", and the continuous improvement of the service level of commercial/retail, finance, communication, transportation/transportation industries, the demand for label printers has increased rapidly. At present, the application of thermal label printers in China has entered a period of rapid popularization, and the market scale continues to grow rapidly.

Application field :
Printing of queuing machines,
shopping mall POS cash registers,
instruments and meters, postal and telecommunications fields,
medical equipment, financial equipment,
tax control cash registers,
lottery machines and various self-service terminal equipment
Characteristic :
The rated operating voltage range is 20-24V, and the power input for each printer adapter is 110V-220V. The output is 20V, 3A.
Main parameters:
24V/2A single power supply
Use special IC to achieve hardware overheating protection
Perfect automatic paper cutter control, half-cut and full-cut can be controlled by software.
Multi-buffer queue structure to achieve continuous and uninterrupted printing Standard RS232 or standard LPT printer interface can be directly
connected to PC or single-chip microcomputer. The serial baud rate can be set by the key.
TB67H450FNG/AFNG features
Single-chip integrated circuit with BiCD process It can realize PWM constant current drive and direct PWM drive. Support four working modes: forward/reverse/briking/stopping (OFF) Built-in output MOSFET with low on-conductivity (high-voltage side + low-voltage side = 0.6Ω (typical)) Achieve high voltage and high current drive, absolute maximum rating: 50V/3.5A Multiple built-in error detection functions (heat shutdown (TSD), overcurrent detection (ISD) and undervoltage locking (UVLO)) Built-in VCC voltage regulator for internal circuit work
Electric water valve control scheme
An electric water valve based on TB67H450
Description:
This power 5W torque 4NM motor driver is a reference design of TB67H450AFNG, which is used to control the forward and reverse rotation and braking of the motor, and realize the automatic switching function of the water valve. This scheme is optimized and equipped with MCU to provide signal feedback function and external control.
Characteristic:
Wide voltage drive 5.5V-24V It supports accurate correction of sampling current, which can achieve high current drive PWM constant current drive and direct PWM drive can be achieved Built-in error detection functions (thermal shutdown (TSD), overcurrent detection (ISD) and undervoltage locking (UVLO)) Supports the forward/reverse/brake/stop (OFF) working modes to achieve accurate position of the motor
